OEM 805338377 The XCMG Sleeve 805338377 is a genuine bushing sleeve that fits inside a bore to guide a pin or shaft on XCMG hydraulic excavators.
Issued under the official part number 805338377, the sleeve gives the technician a correctly sized bearing surface that matches the bore, pin diameter and flange position it is designed for.
The sleeve is turned and finished to the XCMG drawing, so the outside diameter presses into the bore and the inside diameter guides the pin without play.
A smooth inner surface keeps the pin sliding freely, so the joint moves without scoring the shaft or the sleeve wall.
A protective finish resists oil, water and corrosion, so the sleeve keeps its fit and surface through wash-down and long outdoor duty.
Every unit is checked for outside diameter, inside diameter, length and wall thickness before the batch is packed for shipment.
Fitted to pivot joints, linkage bosses, cylinder eyes and pin bores, this sleeve protects the housing and keeps the joint aligned.
The 805338377 sleeve is produced to the XCMG drawing, so the outside diameter presses into the bore and the inside diameter guides the pin on the first attempt.
A smooth inner surface keeps the pin sliding freely, so the joint moves without scoring the shaft or the sleeve wall.
Correct wall thickness keeps the sleeve round under load, so it does not collapse or distort inside the boss.
The finish resists oil, water and wash chemicals, so the sleeve does not corrode or seize to the pin over time.
Because the part matches the OEM number, a fitter installs it straight from the bag without machining or adding shims.
Correct material hardness keeps the bore intact under vibration, so the sleeve does not wear oval on rough ground.
A sound sleeve also protects the housing, so a worn pin damages the cheap sleeve instead of the expensive boss.
Keeping spare sleeves on the shelf shortens repair time, so a worn bushing does not turn into a full day of lost work.
Each lot begins with certified bronze, steel or composite stock tested for hardness, strength and wear resistance before machining.
Sleeves are turned and bored in controlled tooling, so the outside diameter, inside diameter and length stay uniform from batch to batch.
Deburring and honing smooth the bore and chamfer the ends, so the sleeve presses in cleanly and guides the pin without snagging.
Inspectors measure outside diameter, inside diameter, length and wall thickness against a gauge made for this exact part number.
Batch records trace every 805338377 sleeve to its material lot and production run, so a quality question is settled quickly.
A sleeve gives a pin or shaft a smooth bearing surface, so the joint moves without wearing the surrounding housing.
A worn or missing sleeve lets the pin hammer the boss, which wears the bore oval and causes unexpected failure.
The genuine 805338377 keeps the joint tight, so connected parts stay aligned and the housing stays protected.
Correct fit avoids both a sleeve that spins in the bore and one that is pressed in too tight and crushes the pin clearance.
A sound sleeve protects pins, bosses and linkages, which keeps service intervals predictable and extends machine life.
The 805338377 sleeve is installed with a cleaning cloth, a press and a reamer during linkage or hydraulic service work.
Support the joint, remove the pin and clean the bore so no dirt or metal chips enter during the repair.
Check the bore and pin for burrs, rust or oval wear, since a rough surface will stop the sleeve seating straight.
Press the sleeve in squarely with the correct driver, so the bore is not scored and the flange seats against the boss.
Ream or check the inside diameter to the service data, then grease the bore and refit the pin.
Cycle the joint slowly and check that the pin moves freely without play, then grease again after the first working cycles.
At service intervals, look for a loose sleeve, an oval bore or a scored pin and renew the part before the boss wears.
Every 805338377 sleeve is produced in an ISO 9001 and ISO 14001 certified plant with traceability from material to carton.
Incoming material is tested for hardness and strength, and finished sleeves are gauged for outside diameter, inside diameter and length.
Each batch is screened for cracks, porosity and surface defects, since these flaws cause the sleeve to wear or seize under load.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG boss fixture.
Sample sleeves from each batch undergo load, wear and salt spray tests to confirm strength and corrosion performance.
Cheap copies often use soft material or rough bores, so the sleeve wears oval, scores the pin and starts to rattle.
A sleeve with the wrong diameter or wall thickness can spin in the bore, seize on the pin or crack during pressing.
The genuine 805338377 is made to the XCMG drawing, so diameters, length, wall and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM bosses.
Backed by XCMG global quality standards and technical support, this sleeve performs reliably in harsh conditions.
Choosing the genuine 805338377 sleeve prevents a small amount of play from turning into a worn boss or a bent pin.
A failed sleeve lets the pin hammer the housing, which wears the bore oval and shortens component life.
A correctly made sleeve holds firmly, so it does not need repeated replacement and does not wear out the pin.
Reliable sleeves also keep joints tight, 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 805338377 sleeve with efficient turning and boring runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each sleeve.
Protecting the housing with a sleeve prevents expensive repairs, which keeps the machine usable for its full life.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 805338377 sleeve is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is bagged to protect the finish 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 sleeve round and the bore undamaged until fitting, avoiding the distortion seen in loose storage.
