Key Features & Advantages


Precision

Single-Piece Hardened Construction

Eliminates multiple shim stack errors. Uniform HRC 45-50 hardness across entire thrust surface resists grooving.

Leak-Free

Precision Ground Parallel Faces

Flatness and parallelism held within 0.02mm, ensuring even axial load distribution across all planet gear contact points.

Direct Fitment

Correct Thickness Accuracy

Manufactured to exact OEM thickness specification (±0.03mm), restoring factory endplay without trial-and-error shimming.

Rigorous Testing

Wear-Monitoring Groove Design

Radial oil grooves act as visual wear indicators; groove disappearance signals replacement time before catastrophic failure.

FAQ


Q: How to tell if thrust washer failure versus planet gear bearing failure?
A: Thrust washer failure produces rhythmic metallic clicking during track turns or reversing, with axial gear movement visible. Bearing failure causes constant growling regardless of direction. Endplay >0.8mm confirms thrust component wear.
 
Q: What is the correct installation orientation for XKAQ-00213?
A: The side with visible oil grooves faces the rotating planet gear carrier. The smooth side faces the stationary housing. Incorrect orientation blocks oil flow and causes rapid overheating within 50 operating hours.
 
Q: Will XKAQ-00213 fit if my R320LC-7 travel gearbox has been rebuilt before?
A: Not always - travel and swing gearboxes may use different thicknesses even with same outer diameter. Please specify which gearbox you are repairing. Send original thrust ring thickness measurement for 100% match.
 
Q: Does this thrust washer maintain flatness under heavy shock loads and freezing conditions?
A: Yes – 65Mn spring steel maintains dimensional stability under cyclic impact loading. Through-hardened structure prevents cupping or warping even after 5,000+ hours. Impact toughness verified at -40°C without fracture. Proven in granite quarry operations and Siberian winter construction.
 
Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
