OEM 801974527 The XCMG Seal 801974527 is a genuine 210 mm long sealing element that closes the clearance between sliding and fixed surfaces on XCMG excavators.
Issued under the official part number 801974527, the seal gives the technician a correctly sized element that matches the groove width, cavity depth and stroke length it was designed for.
The 210 mm length is molded and trimmed to the XCMG drawing, so the lip covers the full sealing run without being stretched or leaving a bare gap.
The lip profile and body section follow the drawing, so the seal presses against the rod or bore with even contact pressure from end to end.
A compound selected for hydraulic duty resists oil, water and heat, so the seal keeps its elasticity instead of hardening, swelling or cracking.
Every piece is checked for overall length, cross section, lip angle and surface finish before the batch is packed for shipment.
Fitted to cylinder glands, pivot joints, covers and access housings, this seal keeps oil inside, dust outside and machined faces protected.
The 801974527 seal is produced to the XCMG drawing, so the 210 mm length and section fit the groove without cutting, splicing or forcing.
Even lip contact along the whole run means oil stays inside the cavity and dust stays outside, even where the bore is long.
The compound resists oil, water and wash chemicals, so the seal does not swell, soften or crumble during long service hours.
A smooth molded surface lets the seal slide into the groove without snagging, so the lip is not nicked during installation.
Because the part matches the OEM number, a fitter installs it straight from the bag without trimming the length or adding sealant.
Correct compound hardness keeps the lip loaded under vibration, so the seal does not chatter or lose contact on rough ground.
A sound seal also stops oil loss and keeps grit away from bearings and cylinders, which protects expensive internal parts.
Keeping a spare seal on the shelf shortens repair time, so a weeping gland does not turn into a full day of lost work.
Each lot begins with certified rubber or polyurethane compound tested for hardness, tensile strength and oil resistance before molding.
Seals are molded in polished tooling, so the lip profile, body section and 210 mm length stay uniform from batch to batch.
Trimming removes flash from the sealing lip, so the seal seats cleanly and does not leak or wear a groove into the rod.
Inspectors measure length, cross section, lip angle and surface finish against a gauge made for this exact part number.
Batch records trace every 801974527 seal to its compound lot and production run, so a quality question is settled quickly.
A seal closes the clearance between a moving rod and its bore, so oil stays in the cavity and contamination stays out.
A worn or cut seal lets oil weep past the lip and lets grit reach the sliding surface, which scores the rod and wears the gland.
The genuine 801974527 keeps the cavity sealed, so pressure holds and sliding parts stay protected from the environment.
Correct length avoids both a seal that leaves a bare gap and one that buckles in the groove when the piston passes.
A sound seal protects rods, bearings and hydraulic circuits, which keeps service intervals predictable and extends machine life.
The 801974527 seal is installed with a cleaning cloth, a seal pick and assembly grease during cylinder or hydraulic service work.
Release system pressure, drain the affected cylinder and clean the groove so no dirt or metal chips enter during the repair.
Check the groove and bore for burrs, rust or old seal residue, since a rough surface will damage the new lip as it slides in.
Coat the seal with clean assembly grease, then seat it evenly in the groove without twisting or stretching the 210 mm body.
Guide the rod or cover in slowly so the lip passes the bore edge without being cut, and press to the depth in the service data.
Refill with the specified oil, run the machine slowly and check the gland area for weeping after the first pressure cycles.
At service intervals, look for oil film, a scored rod or a hardened lip and renew the part before contamination spreads.
Every 801974527 seal is produced in an ISO 9001 and ISO 14001 certified plant with traceability from compound to carton.
Incoming compound is tested for hardness and oil resistance, and finished seals are gauged for length, section and lip profile.
Each batch is screened for voids, cuts and flash, since these defects cause leaks or let the lip tear under pressure.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG groove fixture.
Sample seals from each batch undergo pressure, heat ageing and oil immersion tests to confirm sealing and compression performance.
Cheap copies often use low-grade compound that hardens or shrinks, so the lip loses contact and the cavity starts to weep.
A seal with the wrong length or section can buckle in the groove, leave a bare gap or tear as the piston passes.
The genuine 801974527 is made to the XCMG drawing, so length, section, lip and compound match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM housings.
Backed by XCMG global quality standards and technical support, this seal performs reliably in harsh conditions.
Choosing the genuine 801974527 seal prevents a small weep from turning into a scored rod or a damaged cylinder.
A failed lip lets oil escape and dust enter, which wears machined surfaces and shortens component life.
A correctly molded seal holds contact firmly, so it does not need repeated replacement and does not leak between services.
Reliable seals also keep pressure contained, which improves machine performance and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 801974527 seal with efficient molding runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each seal.
Sealing cavities prevents oil leaks and contamination, which protects soil, groundwater and internal parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 801974527 seal is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each seal is bagged flat to protect the lip and boxed in a strong carton that guards against dust, damp and crushing.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the 210 mm length straight and the lip undistorted until fitting, avoiding the damage seen in loose storage.
