When they perform well, they are invisible \u2014 silent workhorses converting fluid pressure into precise, controlled movement. When they begin to fail, the consequences can cascade rapidly through a machine&#8217;s entire hydraulic circuit, triggering accelerated wear in pumps, valves, and hose assemblies. Understanding what deterioration actually looks like \u2014 mechanically, visually, and operationally \u2014 is the first step toward cost-effective asset management.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0;\">Hydraulic cylinder failures rarely happen without warning.

Rod seals are fabricated from polyurethane, nitrile rubber, or PTFE composites and are engineered to maintain a fluid film between the seal lip and the hardened chrome rod surface \u2014 thin enough to prevent bulk leakage, thick enough to prevent dry running. Over time, exposure to particulate contamination, thermal cycling, and the mechanical fatigue of repeated stroke cycles causes the seal material to harden, crack, or extrude into the clearance gap.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\">On a Sheffield steel plant or a heavy civil engineering site near Manchester, oil leakage from a boom cylinder is not merely a housekeeping issue. Leaked hydraulic fluid contaminates surrounding components, creates fire risk near hot surfaces, and \u2014 critically \u2014 reduces the effective working pressure available to the cylinder. Once rod seal integrity is compromised, contamination ingress accelerates exponentially, scoring the mirror-polished rod surface and causing irreversible barrel wear.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0;\">A thin film of oil on a freshly wiped rod is borderline \u2014 worth monitoring closely. A visible drip rate, a wet stain that grows between shifts, or oil pooling beneath the machine during stationary periods are unambiguous replacement triggers. At that stage, a seal kit alone rarely resolves the underlying issue; the rod surface itself typically requires re-chroming or replacement, making a complete cylinder exchange the more economical path forward.<\/p>\n<\/div>\n<\/div>\n<p><!-- SIGN 2 --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 0 3% 3% 3%; box-sizing: border-box; background: #f0f4fa;\">\n<div style=\"background: #fff; border-radius: 12px; padding: 3%; box-shadow: 0 2px 12px rgba(26,58,107,0.09); border-left: 5px solid #f4a261; box-sizing: border-box; transition: transform 0.25s, box-shadow 0.25s;\">\n<div style=\"display: flex; align-items: center; gap: 14px; margin-bottom: 14px; flex-wrap: wrap;\">\n<div style=\"background: linear-gradient(135deg, #f4a261, #e07b3a); color: #fff; font-size: clamp(22px, 3vw, 32px); font-weight: 900; width: 52px; height: 52px; border-radius: 50%; display: flex; align-items: center; justify-content: center; flex-shrink: 0;\">2<\/div>\n<h2 style=\"font-size: clamp(17px, 2.5vw + 8px, 24px); color: #1a2233; margin: 0; font-weight: bold;\">Loss of Holding Force and Uncontrolled Drift at Full Extension<\/h2>\n<\/div>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\">A boom cylinder must hold a static load without measurable drift \u2014 this is non-negotiable on any lifting machine operating under the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), which applies across UK construction and quarrying sites. When a boom arm slowly sinks under load with no operator input, the most probable cause is internal bypass past a worn or damaged piston seal. Fluid is migrating from the high-pressure side of the piston to the low-pressure return side, bypassing the load-holding mechanism entirely.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\">Internal bypass is harder to detect than external leakage because there is no visible fluid loss \u2014 the oil simply moves from one side of the piston to the other within a sealed barrel. Operators often report the problem as the machine &#8220;feeling soft&#8221; during lifting operations, or noticing that the boom requires increasingly frequent corrections to maintain position. In Birmingham&#8217;s busy demolition sector, where excavator boom drift during a controlled demolition sequence can have serious safety consequences, this sign demands immediate investigation.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0;\">A straightforward field test involves isolating the cylinder hydraulically at full load extension and monitoring drift over a five-minute window. Any measurable drop in position under full rated load confirms piston seal failure. At this stage, the barrel bore itself should be inspected for scoring \u2014 worn piston seals dragging across a contaminated surface generate metallic debris that accelerates bore damage in a self-perpetuating cycle. Replacement of the complete cylinder unit restores designed holding performance and eliminates the compliance risk associated with drift-prone lifting equipment.<\/p>\n<\/div>\n<\/div>\n<p><!-- SIGN 3 --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 0 3% 3% 3%; box-sizing: border-box; background: #f0f4fa;\">\n<div style=\"background: #fff; border-radius: 12px; padding: 3%; box-shadow: 0 2px 12px rgba(26,58,107,0.09); border-left: 5px solid #2ec4b6; box-sizing: border-box; transition: transform 0.25s, box-shadow 0.25s;\">\n<div style=\"display: flex; align-items: center; gap: 14px; margin-bottom: 14px; flex-wrap: wrap;\">\n<div style=\"background: linear-gradient(135deg, #2ec4b6, #1a9e92); color: #fff; font-size: clamp(22px, 3vw, 32px); font-weight: 900; width: 52px; height: 52px; border-radius: 50%; display: flex; align-items: center; justify-content: center; flex-shrink: 0;\">3<\/div>\n<h2 style=\"font-size: clamp(17px, 2.5vw + 8px, 24px); color: #1a2233; margin: 0; font-weight: bold;\">Erratic Movement, Judder, and Jerky Extension on Low-Demand Cycles<\/h2>\n<\/div>\n<div style=\"display: flex; flex-wrap: wrap; gap: 18px; margin-bottom: 16px;\">\n<div style=\"flex: 2 1 260px;\">\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 12px 0;\"><img decoding=\"async\" class=\"alignleft\" style=\"width: 201px; max-width: 340px; height: 201px; border-radius: 8px; flex: 1 1 200px;\" src=\"https:\/\/boom-cylinders.com\/wp-content\/uploads\/2026\/09\/ep-boom-cylinders.com-1-1.webp\" alt=\"Hydraulic cylinder internal view\" title=\"\">Smooth, proportional movement is the defining characteristic of a healthy hydraulic cylinder. When an operator begins to notice that the boom hesitates before responding, moves in stuttering increments rather than a fluid arc, or produces an audible thumping or clunking sensation through the operator seat, the cylinder&#8217;s internal geometry has likely been compromised. The technical term for this is stick-slip \u2014 a phenomenon where static friction momentarily exceeds the driving hydraulic force, causing the piston to stall before suddenly releasing with excess velocity.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0;\">Stick-slip arises from several concurrent failure modes: rod surface roughness caused by corrosion pitting or mechanical damage, seal material that has hardened and lost its ability to generate a stable lubricating film, or geometric distortion of the barrel bore due to side-loading beyond the cylinder&#8217;s rated specification. Northern UK construction sites \u2014 particularly groundworks contractors operating on soft clay or waterlogged ground \u2014 frequently experience side-loading beyond design limits when machines operate on significant cross-falls.<\/p>\n<\/div>\n<\/div>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0;\">Beyond operator discomfort, stick-slip generates pressure spikes within the hydraulic circuit that exceed the steady-state design rating of connected components. Relief valves cycle unnecessarily, hose end fittings experience fatigue loads at connection points, and downstream control valves are subjected to transient flows far outside their calibration range. A cylinder displaying persistent stick-slip is actively degrading the broader hydraulic system around it, making replacement a cost-avoidance decision as much as a performance one.

This surface integrity is fundamental to seal life. When the chrome layer is compromised by corrosion, mechanical impact, or abrasive contamination ingress, the seal lip encounters a surface it was never designed to accommodate, and wear rates increase by an order of magnitude.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\">The British climate presents specific challenges here. Machines operating on coastal civil engineering projects in areas such as the Humber Estuary or Liverpool Bay are exposed to salt-laden atmospheres that accelerate chrome corrosion, particularly where the rod is left in the extended position during idle periods. Similarly, quarrying sites in the Peak District and Scottish Highlands expose equipment to silica-rich slurry and acidic drainage water that can chemically attack chrome plating over a single winter season.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\">Visual inspection is the appropriate diagnostic tool here. Any visible pitting deeper than approximately 0.1 mm, rust-staining that persists after cleaning, or score marks running axially along the rod are disqualifying defects. Running a fingernail or a fine gauge probe across the rod surface will confirm whether scoring has created a detectable step \u2014 if it has, the rod surface will destroy a new seal kit within hours of installation, making complete cylinder replacement the only rational course of action.<\/p>\n<div style=\"background: #f8f0ff; border: 1px solid #d4b0f5; border-radius: 8px; padding: 3%; margin-top: 8px;\">\n<p style=\"margin: 0; color: #4a0e8f; font-size: clamp(13px, 1.6vw, 15px); line-height: 1.7;\">Rod damage inspection tip: always inspect during machine warm-up when the rod has cycled several times \u2014 thermal expansion reveals pitting that may be masked when cold, and the presence of fresh fluid film makes surface damage easier to distinguish from routine surface wetness.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- SIGN 5 --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 0 3% 3% 3%; box-sizing: border-box; background: #f0f4fa;\">\n<div style=\"background: #fff; border-radius: 12px; padding: 3%; box-shadow: 0 2px 12px rgba(26,58,107,0.09); border-left: 5px solid #1a3a6b; box-sizing: border-box; transition: transform 0.25s, box-shadow 0.25s;\">\n<div style=\"display: flex; align-items: center; gap: 14px; margin-bottom: 14px; flex-wrap: wrap;\">\n<div style=\"background: linear-gradient(135deg, #1a3a6b, #2563b0); color: #fff; font-size: clamp(22px, 3vw, 32px); font-weight: 900; width: 52px; height: 52px; border-radius: 50%; display: flex; align-items: center; justify-content: center; flex-shrink: 0;\">5<\/div>\n<h2 style=\"font-size: clamp(17px, 2.5vw + 8px, 24px); color: #1a2233; margin: 0; font-weight: bold;\">Structural Deformation \u2014 Barrel Bend, Weld Cracking, and Mounting Lug Wear<\/h2>\n<\/div>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\"><img decoding=\"async\" class=\"alignleft\" style=\"width: 270px; max-width: 100%; height: 180px; border-radius: 8px; margin-bottom: 16px;\" src=\"https:\/\/boom-cylinders.com\/wp-content\/uploads\/2026\/09\/ep-boom-cylinders.com-3-1.webp\" alt=\"Hydraulic cylinder structural inspection\" title=\"\">Seals and rods are wear components \u2014 they are expected to degrade over time and can, in many cases, be serviced without replacing the entire cylinder. Structural damage to the barrel, end caps, or mounting attachments is categorically different. When a cylinder barrel exhibits visible bending \u2014 even a deflection of 1 to 2 mm over a 1-metre barrel length \u2014 or when circumferential cracking appears at the barrel-to-endcap weld zone, the cylinder has experienced overload stress beyond its designed structural margin. No rebuild procedure can restore the structural integrity of a bent barrel or a cracked weld without complete remanufacture of the pressure-containing envelope.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\">Mounting lug wear is a related concern. Boom cylinders transmit enormous forces through trunnion-mounted or clevis-mounted attachment points, and the pin-to-bore clearance at these joints is specified tightly \u2014 typically H7\/g6 tolerance on precision assemblies. As the bore wears oval and clearance increases, impact loading at direction reversal generates micro-shock events that propagate fatigue cracks from the lug root into the barrel wall. UK plant hire operations, where machines are frequently re-deployed across different applications by multiple operators, are particularly susceptible to this failure mode through accumulated abuse loading.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0;\">Inspection should include a straight-edge check across the full barrel length and close visual examination of the weld toe in good lighting with a magnifying glass \u2014 or dye-penetrant testing where a fatigue crack is suspected. Mounting lug bores should be measured with an internal bore gauge and compared against the original equipment specification. Any finding that falls outside tolerance is a replacement trigger, regardless of the condition of the seals or rod surface.<\/p>\n<\/div>\n<\/div>\n<p><!-- DIAGNOSTIC TABLE --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 0 3% 3% 3%; box-sizing: border-box; background: #f0f4fa;\">\n<div style=\"background: #fff; border-radius: 12px; padding: 3%; box-shadow: 0 2px 12px rgba(26,58,107,0.09); box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(17px, 2.5vw + 8px, 22px); color: #1a2233; margin: 0 0 16px 0; font-weight: bold;\">Boom Cylinder Failure Mode Diagnostic Reference<\/h2>\n<div style=\"overflow-x: auto; width: 100%; max-width: 100%;\">\n<table style=\"width: 100%; border-collapse: collapse; font-size: clamp(12px, 1.5vw + 8px, 15px); min-width: 560px;\">\n<thead>\n<tr style=\"background: linear-gradient(90deg, #1a3a6b, #2563b0); color: #fff;\">\n<th style=\"padding: 12px 10px; text-align: left; font-weight: bold; border-radius: 6px 0 0 0;\">Symptom<\/th>\n<th style=\"padding: 12px 10px; text-align: left; font-weight: bold;\">Root Cause<\/th>\n<th style=\"padding: 12px 10px; text-align: left; font-weight: bold;\">Serviceable?<\/th>\n<th style=\"padding: 12px 10px; text-align: left; font-weight: bold; border-radius: 0 6px 0 0;\">Recommended Action<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background: #f8faff; transition: background 0.2s;\">\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #1a2233;\">External rod seal leakage<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Seal degradation, rod surface damage<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #e63946;\">Depends on rod condition<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Inspect rod; replace cylinder if rod scored<\/td>\n<\/tr>\n<tr style=\"background: #fff; transition: background 0.2s;\">\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #1a2233;\">Internal drift \/ sinking load<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Piston seal bypass, bore wear<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #e63946;\">Often not \u2014 bore damage likely<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Full cylinder replacement recommended<\/td>\n<\/tr>\n<tr style=\"background: #f8faff; transition: background 0.2s;\">\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #1a2233;\">Stick-slip \/ judder<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Rod roughness, hardened seals, side-loading<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #f4a261;\">Possibly \u2014 early stage only<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Assess rod; reseal or replace<\/td>\n<\/tr>\n<tr style=\"background: #fff; transition: background 0.2s;\">\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #1a2233;\">Pitted \/ corroded rod<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Chrome layer failure, chemical exposure<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #e63946;\">No \u2014 new seals will fail immediately<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Replace cylinder; new rod essential<\/td>\n<\/tr>\n<tr style=\"background: #f8faff; transition: background 0.2s;\">\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #1a2233;\">Barrel bend \/ weld crack<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Overload, fatigue, abuse loading<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #e63946;\">Never \u2014 structural failure<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Immediate decommission and replace<\/td>\n<\/tr>\n<tr style=\"background: #fff; transition: background 0.2s;\">\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #1a2233;\">Worn mounting lug bores<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #2d3a4f;\">Wear, impact loads, pin clearance growth<\/td>\n<td style=\"padding: 11px 10px; border-bottom: 1px solid #dde6f5; color: #f4a261;\">Minor wear: bush lining.

Their overhead travelling crane \u2014 a critical production asset used for positioning steel sections up to 12 tonnes \u2014 had developed progressive drift in the main boom raise cylinder during static holds. An inspection confirmed piston bypass with secondary scoring on the rod surface, ruling out seal-only repair. Three of the four boom cylinders on the crane showed similar wear profiles, consistent with the plant&#8217;s age and the demanding duty cycle of a fabrication environment where crane utilisation exceeds 14 hours per day.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0 0 14px 0;\">The commercial constraint was significant: Broadstone had committed delivery dates on a major structural package for a warehouse development near Doncaster. A conventional rebuild timeline through the OEM parts route would have required a minimum six-week wait for replacement cylinders \u2014 an unacceptable production gap. Working from dimensional drawings provided by Broadstone&#8217;s maintenance team, Ever Power produced four matched replacement cylinders in 18 working days. Each unit was supplied with hard chrome rods ground to Ra 0.32 micrometres, NBR\/PU composite seal packages rated for the site&#8217;s ambient temperature range, and full pressure test documentation to 1.5 times operating pressure.<\/p>\n<p style=\"line-height: 1.85; color: #2d3a4f; margin: 0;\">Installation was completed over a single planned weekend shutdown, with the crane returning to full-rated service on the Monday. The Doncaster delivery schedule was met, and Broadstone subsequently placed a standing order with Ever Power for all future hydraulic cylinder replacements across their Sheffield facility \u2014 a decision driven by documented lead time performance and the dimensional consistency between the four units installed.<\/p>\n<p><!-- REVIEWS --><\/p>\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; margin-top: 24px;\">\n<div style=\"flex: 1 1 240px; background: #f0f7ff; border-radius: 10px; padding: 3%; border-left: 4px solid #1a3a6b; box-sizing: border-box; transition: transform 0.2s;\">\n<div style=\"color: #f4a261; font-size: 18px; margin-bottom: 6px;\">\u2605\u2605\u2605\u2605\u2605<\/div>\n<p style=\"color: #2d3a4f; line-height: 1.75; margin: 0 0 10px 0; font-size: clamp(13px, 1.5vw, 15px); font-style: italic;\">&#8220;The bore geometry on all four cylinders was within 0.02 mm of our original specification.

margin: 0 0 20px 0; font-size: clamp(13px, 1.5vw, 15px);\">Answers to the questions UK plant engineers ask most often about boom cylinder replacement and sourcing.<\/p>\n<div style=\"border: 1px solid #dde6f5; border-radius: 8px; margin-bottom: 12px; overflow: hidden; transition: box-shadow 0.2s;\">\n<details style=\"cursor: pointer;\">\n<summary style=\"padding: 14px 16px; font-weight: bold; color: #1a3a6b; font-size: clamp(13px, 1.6vw, 16px); list-style: none; display: flex; justify-content: space-between; align-items: center; background: #f8faff;\">How do I know whether my boom cylinder in the UK needs a full replacement or just a seal kit?<\/summary>\n<div style=\"padding: 14px 16px; color: #2d3a4f; line-height: 1.8; font-size: clamp(13px, 1.5vw, 15px);\">If the rod surface has visible pitting, scoring, or corrosion, a seal kit alone will not solve the problem \u2014 new seals will fail within hours on a damaged rod. Inspect the rod carefully after cleaning: run a fingernail axially across it. Any detectable ridge or pit means the cylinder should be replaced, not resealed. Internal drift under load also suggests bore wear that a seal kit cannot address. If the rod is clean and the bore is smooth, a seal rebuild is a legitimate and economical repair for leakage that has appeared gradually over time.<\/div>\n<\/details>\n<\/div>\n<div style=\"border: 1px solid #dde6f5; border-radius: 8px; margin-bottom: 12px; overflow: hidden; transition: box-shadow 0.2s;\">\n<details style=\"cursor: pointer;\">\n<summary style=\"padding: 14px 16px; font-weight: bold; color: #1a3a6b; font-size: clamp(13px, 1.6vw, 16px); list-style: none; background: #f8faff;\">What is the typical price range for a custom replacement boom cylinder supplied to a UK construction site?<\/summary>\n<div style=\"padding: 14px 16px; color: #2d3a4f; line-height: 1.8; font-size: clamp(13px, 1.5vw, 15px);\">Pricing for custom replacement boom cylinders varies significantly depending on bore size, stroke length, pressure rating, material grade, and mounting configuration. Small to mid-range cylinders in the 80\u2013160 mm bore range for standard construction equipment typically price between \u00a3800 and \u00a33,500 per unit when manufactured to specification. Larger units for crane or heavy-lift applications exceed these figures.

Ever Power manufactures bespoke boom cylinders from raw tube material and delivers to UK plant hire operations across the Midlands, typically within 10 to 18 working days for most bore and stroke combinations.

Quarrying applications with high silica dust exposure, coastal sites with salt contamination, and machines operating on extreme cross-falls will see shorter service intervals. Scheduled hydraulic oil and filter changes, and keeping the cylinder rod retracted during long idle periods, are the most effective service life extension measures.<\/div>\n<\/details>\n<\/div>\n<div style=\"border: 1px solid #dde6f5; border-radius: 8px; margin-bottom: 12px; overflow: hidden; transition: box-shadow 0.2s;\">\n<details style=\"cursor: pointer;\">\n<summary style=\"padding: 14px 16px; font-weight: bold; color: #1a3a6b; font-size: clamp(13px, 1.6vw, 16px); list-style: none; background: #f8faff;\">Where can I get a reliable quote for boom cylinder replacement from a supplier who ships to Birmingham, Sheffield, or Manchester?<\/summary>\n<div style=\"padding: 14px 16px; color: #2d3a4f; line-height: 1.8; font-size: clamp(13px, 1.5vw, 15px);\">Ever Power supplies replacement and custom boom cylinders to customers throughout the UK, including regular deliveries to Birmingham, Sheffield, Manchester, and Leeds.
