This is a hydraulic swing motor repair kit, containing seals, O-rings, and potentially other small components needed to restore the function of the swing motor on excavators. It is manufactured to precise tolerances, ensuring a leak-free seal and smooth operation, unlike a kit with degraded or incorrectly sized seals. A worn swing motor may exhibit slow or jerky swing movements, excessive heat in the hydraulic fluid, or audible grinding noises.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a failing swing motor, often addressed by this kit, is a noticeable reduction in the speed or smoothness of the excavator's swing function. If left unrepaired, the motor may become increasingly sluggish, lose its holding torque, or develop significant leaks, potentially leading to uncontrolled movement or hydraulic system overheating. Continued operation risks damage to the swing gear and bearing, necessitating a more extensive and costly repair.
Thoroughly clean all internal surfaces of the swing motor housing before installing new seals to prevent contamination. Ensure all O-rings are properly seated and lubricated with appropriate hydraulic fluid before reassembly.
Inspect the swing motor gears, bearings, and hydraulic lines for wear or damage during the overhaul process.
