1473400 Spindle — Cat 120H 120H eS

This spindle is a crucial rotating shaft that supports and allows for the precise rotation of components within the final drive or axle assembly. Manufactured to meet exacting standards, it provides a durable and smooth bearing surface, unlike a worn spindle which may show signs of scoring, pitting, or excessive play. Operators may experience abnormal noises such as grinding or clicking from the wheel end, or notice a wobble or looseness in the wheel assembly when this spindle is compromised.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first symptom of a failing spindle is often an audible grinding or knocking noise originating from the wheel end, especially during turns. If ignored, the wear will progress, leading to excessive play in the wheel assembly and potentially uneven tire wear. Continued operation risks the wheel hub becoming unstable, which could compromise steering control.

Installation Tip

Ensure the mating surfaces of the spindle and axle housing are perfectly clean and free from any burrs or damage before assembly. Avoid hammering the spindle into place, as this can damage the bearing surfaces or the spindle itself.

Service Note

Always replace the wheel bearings and seals when replacing a spindle, as they are subject to similar wear patterns and stresses.
