The 800107065 Thrust Plate is a genuine XCMG axial bearing component designed for motor grader transmissions, final drives, and steering clutch housings. This precision‑ground thrust washer, also known as an axial plate or thrust ring, provides a low‑friction hardened surface that absorbs axial loads from gears, shafts, and planetary carriers. Manufactured from high‑carbon alloy steel with a precision flat and parallel finish, the 800107065 thrust plate ensures correct gear end‑play, reduces wear on mating castings, and extends the service life of your XCMG GR series motor grader’s drivetrain.
The 800107065 thrust plate is a direct replacement for worn, scored, or warped plates in XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. Typical applications include the transmission gear pack end bearings, differential side adjuster thrust faces, and steering clutch piston support. The plate features a superfinished mating surface with oil retention grooves, ensuring consistent lubrication and preventing seizure under high thrust loads.
A worn or missing thrust plate allows excessive axial movement, leading to gear misalignment, clutch pack preload loss, and rapid failure of bushings and housings. Replacing a degraded plate with the genuine XCMG 800107065 restores proper end clearance, eliminates thrust‑related noise, and protects expensive transmission components from premature destruction.

The XCMG 800107065 thrust plate is installed between rotating gear packs or planetary carriers and stationary transmission housings. Its primary function is to absorb axial thrust generated by helical gear teeth and clutch pack compression, ensuring that end‑play remains within design limits.
Without a properly functioning thrust plate, gear trains can shift axially, leading to misalignment, irregular tooth contact, increased noise, and rapid fatigue failure. The 800107065 plate provides a durable, low‑friction surface that allows smooth axial movement while carrying high compressive loads.
When the thrust plate becomes worn beyond tolerance (typically thickness reduction >0.2 mm), end‑clearance increases, causing clutch pack preload loss and gear hunting. Replacing a worn plate with genuine 800107065 restores factory axial settings, eliminates drivetrain vibration, and prevents catastrophic housing damage.
Each 800107065 thrust plate is blanked from high‑quality 20CrMnTi alloy steel strip, then double‑disc ground to achieve exceptional flatness and parallel tolerances of 0.02 mm. The plates are then case‑carburized to a depth of 0.5‑0.8 mm and hardened to 58–62 HRC.
After hardening, the working faces are lapped to a mirror finish (Ra ≤ 0.4 µm) and fitted with precision‑machined oil grooves. The groove pattern optimizes oil film retention, preventing metal‑to‑metal contact during boundary lubrication conditions. This is critical for motor grader transmissions that see frequent start‑stop and direction changes.
Each plate is 100% inspected for thickness, flatness, and hardness. XCMG’s quality system includes sample destructive testing for load‑deflection characteristics and metallographic analysis. Only plates meeting all specifications are packaged with anti‑rust oil and part labeling.
To replace the 800107065 thrust plate, remove the transmission or final drive housing cover and extract the gear shaft or planetary assembly. Clean the housing seat and the mating surface on the gear or clutch hub – any debris will affect thickness measurement.
Insert the new thrust plate into its seat (oil groove side facing the rotating component). Some housings use locating pins or a recess to prevent rotation; ensure the plate is seated correctly. Measure end‑play with a dial indicator after assembly; acceptable clearance is 0.10–0.25 mm for most XCMG transmissions.
If clearance is outside specification, XCMG offers selective thickness thrust plates. Lubricate the plate liberally with transmission fluid before final assembly. Torque all fasteners to factory values and run the grader under no load, checking for unusual axial clunking or heat generation.
Typical symptoms of a worn 800107065 thrust plate include: axial knocking or clunking during gear shifts, metal particles (especially silver flakes) in the oil, excessive end‑float measurable at the output shaft, and clutch pack drag due to incorrect stack height.
If the plate becomes badly scored or spalled, the housing surface may also be damaged, requiring replacement of the case or a repair sleeve. Do not ignore signs of thrust wear – a failed plate can allow a gear to contact the housing, leading to a cracked transmission case and complete drivetrain failure.
Aftermarket thrust plates are often made from mild steel or untreated spring steel that work‑hardens and cracks under repeated axial impacts. They may lack proper flatness, leading to localized high spots that cause rapid wear of the mating gear hub.
Counterfeit plates frequently have incorrect thickness, resulting in end‑play outside specification. Too much clearance causes gear clashing; too little preload leads to overheating and seizure. Genuine XCMG 800107065 plates are manufactured to exact dimensional and metallurgical standards, ensuring consistent performance.
XCMG provides a 12‑month warranty against manufacturing defects. Each plate is etched with the XCMG logo and part number. Using genuine XCMG thrust plates protects your grader’s transmission investment and ensures reliable axial control for thousands of operating hours.
Inspect the 800107065 thrust plate during major transmission overhauls (every 3,000‑4,000 hours) or whenever the drivetrain is disassembled for other repairs. Measure thickness at four points around the circumference; if any measurement is below 3.8 mm (95% of new), replace the plate.
Also inspect the mating housing surface for scoring or fretting. If grooves deeper than 0.1 mm are present, the housing should be remachined or a thicker selective thrust plate installed. Always replace all thrust plates in a given shaft line as a set – mixing worn and new plates leads to uneven loading.
Keep a spare 800107065 thrust plate in your parts inventory for emergency repairs. Proper lubrication (clean, correct viscosity oil) dramatically extends plate life. Change transmission oil and filters at the intervals specified in your XCMG operator’s manual.
