Top gear shaft pilot bearing replacement involves transmission disassembly. Professional installation by a qualified technician using specialized tools is recommended. Thoroughly clean the crankshaft end bore and bearing mounting position before installation, ensuring no old bearing residue or contaminants. A dedicated bearing installation tool must be used, applying even pressure; never hammer the bearing directly.
- Remove transmission: Safely lift the vehicle, remove propeller shaft and transmission mounting bolts, separate transmission from engine.
- Extract old bearing: Use a bearing puller to extract old pilot bearing, taking care not to damage crankshaft end bore.
- Clean mounting position: Thoroughly clean crankshaft end bore, removing old bearing residue, oil, and rust.
- Install new bearing: Use dedicated bearing installation tool to press new bearing evenly into crankshaft end bore, ensuring bearing face is flush with crankshaft face.
- Install transmission: Reinstall transmission to engine, ensuring input shaft correctly engages pilot bearing inner ring.
- Tighten bolts: Tighten transmission mounting bolts to specified torque.
- Road test: Start engine, check for smooth gear shifting and absence of abnormal noise.
- Every 50,000 km: Check transmission shifting smoothness and for abnormal noise.
- Every 100,000 km: Inspect pilot bearing condition; replace if necessary.
- When difficult shifting or transmission noise is detected: Inspect pilot bearing and transmission input shaft condition promptly.
