High-strength 38T ball guide for CAT330D/E336CG SBS180 travel motor, restoring stable travel performance and hydraulic efficiency.
OEM-matched 167-3863 ball guide for CAT330D / E336CG travel motor
Designed for SBS180 final drive rotating group assembly
Precision-machined 38T structure ensures smooth travel motor rotation
Heat-treated alloy steel for maximum strength and wear resistance
Ideal for hydraulic repair shops, fleet maintenance, and aftermarket distributors
The YNF16425 Ball Guide, replacing OEM 167-3863, is engineered for the CAT330D / E336CG excavator equipped with the SBS180 travel motor. As a critical rotating group component, the ball guide ensures smooth movement of the piston set, stabilizing hydraulic pressure distribution within the final drive motor. A worn ball guide often leads to abnormal vibration, reduced travel torque, overheating, or complete motor failure.
Manufactured with heat-treated alloy steel and precision CNC machining, this 38-tooth ball guide delivers excellent dimensional accuracy, hardness, and fatigue resistance—essential for high-load travel applications. Its enhanced structural design improves oil flow and ensures stable motor efficiency even under intense working conditions.
Trusted by hydraulic rebuild workshops, equipment rental fleets, and aftermarket suppliers, the YNF16425 ball guide offers a cost-effective, reliable replacement to restore full travel motor performance and machine mobility.
