The XCMG genuine 273100557 Static Friction Plate is a precision‑engineered OEM component designed for motor grader transmissions, clutch packs, and brake systems. This friction plate, with OEM number 273100557, transfers torque and provides smooth engagement in heavy‑duty grading applications. Manufactured to XCMG’s original specifications, the 273100557 Static Friction Plate ensures consistent friction performance, high heat resistance, and extended service life under extreme loads.
The 273100557 friction plate is a critical wear item in XCMG GR series motor graders, including GR135, GR165, GR180, GR215, GR260, GR300, and GR350 models. It is used in the main transmission clutch pack, differential lock mechanisms, and parking brake systems. Without a properly functioning static friction plate, gear slippage, overheating, and complete transmission failure can occur.
Made from high‑grade paper‑based friction material bonded to a steel core, the 273100557 plate delivers stable coefficient of friction across temperatures from -40°C to +150°C. Replacing worn friction plates with genuine XCMG 273100557 restores original shift quality and prevents costly drivetrain damage.

The 273100557 Static Friction Plate is a core component inside the transmission clutch pack. When hydraulic pressure is applied, the friction plate engages against a steel separator plate, transmitting engine torque to the planetary gear sets.
Without a healthy static friction plate, clutch slippage occurs, causing erratic shifting, overheating, and eventual loss of drive power. In XCMG GR graders, the 273100557 plate ensures positive engagement for forward/reverse clutches and speed ranges.
This plate also serves in the parking brake system, holding the grader stationary on slopes. Worn friction material reduces braking force, creating safety hazards. Replace with genuine 273100557 to restore factory stopping performance.
Each 273100557 Static Friction Plate is manufactured using a high‑energy friction material formulation developed by XCMG’s powertrain division. The paper‑based matrix contains proprietary fibers and friction modifiers that deliver stable torque capacity even after hundreds of thermal cycles.
The steel core is stamped from high‑carbon C50 sheet, then heat‑treated to HRC 35‑40 to resist warping under clamp loads. Oil grooves are precision‑machined on both sides to improve cooling and prevent glazing. The friction lining is bonded with a high‑temperature phenolic resin that withstands flash temperatures up to 300°C.
Every batch of 273100557 plates is tested for static coefficient of friction, dimensional accuracy, and shear strength. XCMG’s quality control ensures identical friction characteristics to the original plate, so shift feel and timing remain unchanged.
Before installing the new 273100557 plate, drain the transmission fluid and remove the clutch pack housing. Inspect steel separator plates for scoring or discoloration; replace any damaged ones. Clean all components with brake cleaner and allow to dry.
Soak the new static friction plate in clean ATF or XCMG transmission oil for at least 30 minutes before assembly. This pre‑lubrication prevents initial dry start‑up and ensures proper friction characteristics. Stack the friction plates and steel plates alternately as per the service manual orientation.
Torque the clutch pack retaining bolts to 35 Nm using a calibrated wrench. Fill the transmission with the correct oil grade, then run the grader at idle, cycling through all gears to expel trapped air. Re‑check fluid level after a short test drive.
Delayed engagement when shifting from neutral to drive, slipping during uphill grading, and increased transmission oil temperature are classic signs. Also, erratic downshifting or a burnt smell from the dipstick indicates friction plate degradation.
If the grader fails to move when throttle is applied but engine revs freely, the 273100557 friction plate may be completely worn. Immediate replacement is required to avoid damaging the planetary gears and clutch housing surfaces.
XCMG recommends inspecting the clutch pack every 2,500 operating hours or anytime transmission fluid darkens significantly. The 273100557 Static Friction Plate should be replaced as part of a full clutch rebuild at 5,000‑hour intervals for standard duty cycles.
For graders that perform heavy ripping or continuous blade work, shorter replacement intervals (3,000‑4,000 hours) are advised. Always replace the complete set of friction plates and separator plates together to ensure even wear and proper clearance.
Using genuine XCMG 273100557 plates guarantees material compatibility with transmission seals and pistons. Aftermarket plates may have incorrect thickness or friction coefficient, leading to improper clutch pack stack height and premature failure.
Every genuine XCMG 273100557 Static Friction Plate comes with a 12‑month warranty against manufacturing defects. XCMG regional hubs in Houston, Rotterdam, Dubai, and Shanghai maintain deep stock of this high‑demand friction plate.
Emergency air freight delivers the 273100557 plate to most global destinations within 3‑5 business days. For fleets, consignment inventory programs are available to prevent downtime. Order the exact OEM part and avoid generic substitutes that compromise your grader’s transmission reliability.
