Installation & Usage Guide

Installation Steps

1. Park harvester on flat ground, shut down engine and cut off power. Jack‑up the target crawler side to lift track off ground.

2. Loosen crawler tension device and release crawler tension properly.

3. Remove fixing bolts, take out old damaged big roller assembly.

4. Clean mounting seat, remove mud, rust and debris.

5. Place new RV01401130001 big roller assembly into mounting position.

6. Install and tighten fixing bolts to required torque.

7. Reset crawler tension to factory standard value.

8. Rotate crawler manually to confirm free rotation without jamming, then perform harvester test‑run.

Important Notes

1. Inspect roller wear, oil seal and grease condition each working season. Replace assembly when wear, oil leakage or seizure occurs.

2. Keep mounting seat flat and clean during installation. Do not use deformed assembly.

3. Check bolt tightness regularly when working in muddy and paddy field.

4. Maintain correct grease filling for roller assembly; do not run without lubrication.

5. If crawler shakes or runs unsmoothly after replacement, inspect other undercarriage components together.

Trouble‑shooting

• Abnormal noise: Check bolt tightness, bearing damage or foreign matter stuck.

• Oil leakage: Check oil seal aging or damage, replace whole assembly.

• Roller cannot rotate: Confirm sufficient lubrication, check bearing failure.
