The 800107064 Wear Pad is a genuine XCMG wear component designed for the circle support, blade lift linkage, and articulation joints of motor graders. This precision‑molded wear pad, also referred to as a glide pad or sliding , provides low‑friction axial and radial support while absorbing shock loads during grading operations. Manufactured from advanced self‑lubricating composite material, the 800107064 wear pad eliminates metal‑to‑metal contact, reduces maintenance intervals, and extends the life of mating steel surfaces on XCMG GR series graders.
The 800107064 wear pad is a direct replacement for worn or cracked pads on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. Common applications include the circle rotation support ring, blade tilt pivot, and rear articulation joint. The pad features an optimized groove pattern for grease retention and debris evacuation, ensuring consistent lubrication even under extreme dust and moisture exposure.
A worn or missing wear pad allows excessive clearance, causing impact loading, erratic blade movement, and accelerated wear of the circle gear and mounting hardware. Replacing a degraded pad with the genuine XCMG 800107064 restores original clearances, eliminates play, and protects the grader’s precision grading capabilities.

The XCMG 800107064 wear pad is installed between the circle rotation ring and the grader’s main frame, as well as in the blade tilt and side‑shift pivots. It provides a low‑friction sliding surface that accommodates both axial thrust and radial oscillation during blade positioning.
Without a functional wear pad, the circle gear will contact the frame directly, causing metal galling, excessive backlash, and loss of blade angle precision. The 800107064 pad’s self‑lubricating properties reduce grease consumption and prevent dry‑start damage.
When the pad wears beyond the thickness limit (typically 10% reduction), clearance increases, leading to vibration, imprecise grading, and accelerated pin wear. Replacing worn pads with genuine 800107064 restores factory clearances, smoothens circle rotation, and protects the pivot bores.
The 800107064 wear pad is compression‑molded from a proprietary fabric‑reinforced phenolic resin blend infused with PTFE (polytetrafluoroethylene) and molybdenum disulfide. This composition delivers excellent compressive strength and a permanent low‑friction surface that does not require running‑in.
Unlike bronze or steel wear plates, the composite material will not corrode or score the mating steel ring. The built‑in solid lubricants are uniformly distributed, ensuring consistent friction even if grease supply is temporarily interrupted.
The pad’s cross‑hatched groove pattern holds grease and allows debris to be forced out during oscillation, preventing abrasive wear. Each 800107064 pad is heat‑stabilized to maintain dimensional accuracy across the full operating temperature range.
To replace the 800107064 wear pad, first remove the circle support access covers or unload the circle pivot. Clean the seating surface on the frame and the ring thoroughly – remove any old adhesive or debris.
Apply a thin layer of lithium grease to the back side of the pad to prevent fretting. Position the new pad into the machined pocket; it should sit flush without rocking. Install retaining pins or bolts as per the grader’s design (some pads are bonded, others mechanically retained).
After installation, measure the clearance between the ring and frame using feeler gauges. Acceptable clearance is 0.2–0.5 mm for a new pad. Lubricate the pad via existing grease fittings until fresh grease appears at the pad edges. Cycle the circle left and right to seat the pad.
Typical symptoms of a worn 800107064 pad include: excessive radial play in the circle (visible when pushing the blade sideways), erratic blade drift, metal particles on the circle gear, and a rough, jerky feel when rotating the circle.
If the pad cracks or disintegrates, the steel ring will contact the frame, causing grinding noises and rapid wear of both surfaces. Replace all pads in the same wear set simultaneously to maintain even load distribution. Do not wait until the pad fails completely.
Aftermarket wear pads are often made from low‑density nylon or recycled thermoplastics that cold‑flow under load, rapidly increasing clearance. They may lack the necessary PTFE content, resulting in higher friction and grease dependency. Only genuine XCMG 800107064 pads meet the exact material formulation, hardness, and dimensional stability required for motor grader circles.
Counterfeit pads may slip or crack within months, allowing metal‑to‑metal contact that damages the expensive circle ring. Genuine XCMG pads are batch‑tested for compressive strength, friction coefficient, and wear rate using a full‑scale circle simulator.
XCMG offers a 12‑month warranty against manufacturing defects. Each 800107064 pad is marked with the XCMG logo and date code. Using genuine wear pads preserves your grader’s resale value and ensures many seasons of precise grading.
Inspect the 800107064 wear pads every 500 operating hours or during any circle‑related service. Check for visible cracking, compression set, or uneven wear. Measure clearance at three points around the circle; if clearance exceeds 1.0 mm, replace the pads.
Always grease the pad through its designated fitting after every 50 hours of operation. Use NLGI #2 lithium grease with EP additives. Over‑greasing is not harmful – excess grease will simply purge from the grooves. Keep spare 800107064 pads in your parts inventory to avoid downtime.
When replacing circle wear pads, inspect the mating steel ring for scoring or grooves. Light scratches can be polished, but deep grooves require ring replacement. A smooth ring surface will extend the life of the new 800107064 pads.
