OEM 803095748 The XCMG Tension Cylinder Seal Kit 803095748 is a genuine seal set that restores the hydraulic tension cylinder on XCMG crawler excavators.
Issued under the official part number 803095748, the kit gives the fitter every seal, ring and wiper needed to rebuild one tension cylinder.
The piston seal, rod seal, wiper, O-rings and back-up rings are all molded to the XCMG drawing for the cylinder bore and rod size.
Oil-resistant NBR compound is standard, with tougher compounds available where the undercarriage sees high heat or heavy duty.
Each part is checked for diameter, section, hardness and surface finish, then bagged together so nothing is missing at the bench.
A complete kit means the cylinder is resealed in one pass, which avoids a second strip-down when an old ring starts to leak.
Fitted to the track adjuster cylinder, this seal kit keeps grease pressure inside, so the chain stays tensioned and tracks straight.
The 803095748 kit is molded to the XCMG drawing, so every seal matches the cylinder bore, rod size and groove width.
A complete kit means the cylinder is fully resealed in one strip-down, so labour is spent once instead of twice.
The piston seal holds pressure on the grease side, so track tension stays where the operator sets it.
The rod seal and wiper keep grease in and grit out, which stops the rod from scoring and the seal from cutting.
Back-up rings close the extrusion gap, so the soft lip keeps its shape under full tensioning pressure.
Because the number matches the OEM part, the fitter installs each piece without trimming, stretching or guessing sizes.
Oil-resistant compound resists swelling and hardening, so the seals keep contact through hot and cold working cycles.
A sound seal kit protects the cylinder barrel and rod, which is far cheaper than replacing the whole tension cylinder.
Each lot starts with certified NBR or FKM compound tested for hardness, tensile strength, oil swell and compression set.
Parts are molded in polished tools under controlled heat and pressure, so lips and O-rings come out dense with no voids.
Trimming removes the parting line bead, leaving sealing edges that stay smooth around the full circumference.
Inspectors measure diameter, section and hardness on each part, then check the bag against the kit list for this part number.
Records link every 803095748 kit to its rubber lots and molding presses, so a technical question is answered from documents.
A track tension cylinder uses grease pressure to push the idler forward, and the seals are what keep that pressure inside.
A hardened or cut seal lets grease escape, so the idler creeps back, the chain slackens and the track starts to slap.
The genuine 803095748 restores the original seal geometry, so pressure is held and the chain keeps the tension the operator set.
Correct lip pressure avoids both grease weeping past the wiper and excess friction that wears the rod and heats the seal.
A sound kit protects the idler, chain and final drive, which keeps undercarriage costs predictable over the machine life.
The 803095748 kit is fitted with a seal pick, a guide sleeve, a grease gun and a torque wrench during cylinder repair.
Park on firm level ground, release track tension, clean the frame area and remove the cylinder from the track adjuster.
Strip the cylinder, then inspect the bore and rod for scoring, corrosion or a worn seal track before fitting new seals.
Lubricate each seal with clean grease, fit the back-up rings on the pressure side and seat every part square in its groove.
Slide the piston and rod in with a sleeve so the lips are not rolled, then close the cylinder to the specified torque.
Refit the cylinder, pump grease slowly to set chain sag to the XCMG specification, and track the machine in both directions.
At service intervals, look for grease leaks, a rod that will not hold or slack on one side and renew the kit before the chain is damaged.
Every 803095748 kit is produced in an ISO 9001 and ISO 14001 certified plant with traceability from compound to carton.
Incoming rubber is tested for hardness and oil swell, and finished parts are gauged for diameter, section and roundness.
Each batch is screened for voids, cracks and flash, since these defects open leak paths straight through a seal.
Release checks combine visual review, dimensional verification and a trial fit in the XCMG tension cylinder fixture.
Samples from every lot go through oil soak, heat ageing and compression set testing to confirm long-term sealing.
Low-cost kits often use rubber that hardens in a season, so the rod seal leaks and the chain loses tension within weeks.
A seal with the wrong section can be over-squeezed on fitting or sit loose in its groove, and both cases end in leaks.
The genuine 803095748 is molded to the XCMG drawing, so diameter, section and hardness agree with the original parts.
Genuine parts also preserve warranty cover, protect resale value and keep compatibility with the rest of the cylinder.
Backed by XCMG global quality standards and technical support, this seal kit performs reliably in harsh conditions.
Using the genuine 803095748 kit keeps a leaking tension cylinder from becoming a full cylinder or undercarriage repair.
A failed seal lets grease escape, the chain slackens and the track can jump the sprocket, stopping the machine on site.
Resealing with a complete kit restores full tensioning, so the idler, chain and final drive are spared excess shock load.
Reliable sealing extends chain and roller life, which lowers the total cost of ownership across a working fleet.
Maintenance histories from construction and mining sites show genuine XCMG seal kits reduce unplanned stoppages.
XCMG molds the 803095748 kit with efficient cycles and close material control that keep production scrap low.
Resealing an existing cylinder instead of scrapping it saves steel, chrome and the energy used to make a new one.
Stopping grease leaks protects soil and groundwater, helping operators meet rules on environmentally sensitive sites.
The rubber in this kit complies with RoHS and REACH requirements for safe handling and responsible recycling.
The 803095748 seal kit is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each kit is bagged with its parts listed and boxed in a strong carton that guards against dust, damp and distortion.
Fleet buyers can ask for volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests quickly, so machines return to work sooner.
Careful packing keeps seals round and lips clean until fitting, avoiding the deformation seen in badly stored kits.
