Common Faults and Troubleshooting Methods for Wheel Loader Drive Axles

In wheel loader drive axles, the main reducer, differential, and wheel-side reducers generally do not experience faults. However, if improper assembly or severe oil shortage occurs, severe faults may still arise, as detailed below:

1. Abnormal Noise in Front and Rear Drive Axles

Fault Characteristics and Causes:

(1) Abnormal meshing of main drive gears;

(2) Excessive clearance or damage to tapered bearings;

(3) Severe wear of differential planetary gears or washers.

Troubleshooting Methods:

(1) Inspect and adjust;

(2) Adjust or replace;

(3) Replace.

2. Abnormal Noise in Wheel-Side Reducers

Fault Characteristics and Causes:

(1) Damage to needle bearings of planetary gears;

(2) Damage to planetary gear spacers, leading to damage of needle bearings and other meshing gears.

Troubleshooting Methods:

(1) Replace all damaged parts;

(2) Identify the cause of spacer damage and replace the damaged parts.
