The 273100568 Friction Disc is a genuine OEM clutch plate manufactured by XCMG for motor graders and heavy construction equipment. This precision‑bonded friction disc, also known as a clutch friction plate or brake lining disc, provides the necessary friction coefficient for power shift transmission clutch packs and wet brake systems on XCMG GR series motor graders. Manufactured from high‑temperature resin matrix with sintered bronze or organic friction material, the 273100568 friction disc is designed to withstand extreme heat, oil immersion, and high torque loads in demanding grading environments.
The friction disc 273100568 is a direct replacement for worn, glazed, or delaminated discs on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. Typical applications include forward and reverse clutch packs in the power shift transmission, circle drive wet clutch, parking brake assembly, and differential lock clutch. The disc features a precision‑machined steel core with bonded friction material on both faces, and internal splines or drive lugs that match the mating hub.
A worn or burnt friction disc leads to clutch slippage, loss of drive, erratic shifting, and eventual transmission failure. Replacing damaged discs with the genuine XCMG 273100568 restores proper torque transfer, smooth engagement, and extended drivetrain life.

The XCMG 273100568 Friction Disc is a key component of the grader’s power shift transmission clutch packs. During gear changes, hydraulic pressure applies the clutch pack, compressing alternating friction discs and steel separator plates. The friction material on the disc generates the torque needed to drive the planetary gear sets. Without correctly functioning friction discs, the transmission will slip, overheat, and fail.
In the circle drive wet clutch, the friction disc 273100568 engages the drive to rotate the moldboard. A worn disc causes the circle to stop rotating under load, affecting grading accuracy. The parking brake also uses a friction disc stack – a badly worn disc can compromise parking brake holding capacity, a serious safety hazard.
Differential lock clutches employ the 273100568 disc to lock the differential for improved traction in slippery conditions. A burnt or glazed disc may cause the differential lock to disengage unexpectedly, reducing machine capability. Using genuine XCMG friction discs ensures consistent friction coefficient and reliable engagement across all applications.
Each 273100568 friction disc begins with a stamped steel core, which is shot‑blasted to clean and roughen the surface. The friction material (a proprietary blend of synthetic fibers, friction modifiers, and high‑temperature resin) is then bonded to both sides using a precision‑controlled compression molding process. The bonded disc is then heat‑treated to cure the resin and stabilize the material.
After bonding, the disc is ground to final thickness on a twin‑disc grinder. The friction surface is then grooved with a spiral or waffle pattern (depending on application) to improve oil flow and cooling. Every disc is 100% inspected for thickness, flatness, and bond integrity using ultrasonic testing. Random samples are tested for coefficient of friction on a dynamometer.
XCMG’s quality system ensures that each friction disc meets the original equipment friction and wear standards. The disc is packed in a sealed bag with a desiccant to prevent moisture absorption. A laser‑etched part number provides traceability.
When rebuilding a clutch pack, always replace all friction discs and steel separator plates as a set. Remove the old discs and inspect the clutch housing for wear. Clean all components thoroughly with transmission fluid – do not use solvent that could damage new friction material.
Soak new friction discs 273100568 in clean transmission oil for at least 30 minutes before assembly. This ensures that the friction material is fully saturated. Install the discs alternately with steel separator plates, following the correct order and orientation (splined edges toward the hub). Use a clutch pack compression tool to compress the stack, then install the retaining snap ring.
After assembly, verify the clutch pack clearance (end‑play) using a feeler gauge; adjust by selecting appropriate thickness of backing plate if required. Incorrect clearance will cause clutch drag or slippage. Always consult the workshop manual for model‑specific clearance specifications.
Aftermarket friction discs often use inferior friction materials that glaze quickly or disintegrate under high heat. The genuine XCMG disc uses a proprietary resin‑bonded formulation that maintains stable friction throughout the disc’s life. Aftermarket discs may also have incorrect thickness, causing improper clutch pack clearance and engagement issues.
Counterfeit friction discs may have weak bond adhesion between the friction material and the steel core, leading to delamination and clutch failure. The 273100568 disc is ultrasonically tested for bond integrity. In addition, genuine XCMG discs have the XCMG logo and part number stamped on the steel core. Using genuine discs ensures reliable torque transfer and long transmission life.
XCMG provides a 12‑month warranty against manufacturing defects. Choose genuine for safety and confidence.
Common signs of friction disc failure include: transmission slippage (engine revs but grader moves slowly), burning smell from the transmission, delayed or harsh shifting, parking brake unable to hold on slopes, and differential lock not engaging. Measuring the disc thickness below the minimum wear limit (2.8 mm) also indicates replacement is required.
Preventive replacement is recommended during any transmission overhaul (every 6,000‑8,000 operating hours) or when the clutch pack is disassembled for other repairs. Even if the discs appear undamaged, the friction material may have lost its original friction properties. Always replace as a complete set.
Keep a set of 273100568 friction discs in your parts inventory. A failed disc can cause sudden loss of drive, especially when operating in heavy conditions. Prompt replacement prevents damage to the steel separator plates and clutch housing.
