Pre-Installation Requirements
-
Essential Tools
- 200-400Nm digital torque wrench (calibrated within 3 ເດືອນ)
- Bearing puller set (50-150mm range)
- Dial indicator with 0.001mm resolution
-
Consumables
- LOCTITE 574 flange sealant (100ml tube)
- Mobil SHC Gear 85W-140 lubricant
Installation Process
Step 1: Component Removal
- Drain transmission oil through 28mm hexagonal drain plug (minimum 15min drainage)
- Mark original shim positions with alignment punches (every 45°)
- Remove retaining rings using JIS V-32 circlip pliers
Step 2: Surface Preparation
- Clean mating surfaces with non-chlorinated brake cleaner
- Apply sealant in spiral pattern:
- 3mm continuous bead around bolt holes
- 5mm offset from oil channels
Step 3: Assembly Installation
| Component |
Torque Sequence |
Specification |
| M12 bolts |
85Nm → 105Nm → 120° angle |
Cross-tightening |
| Bearing nuts |
180Nm + 90° rotation |
Dynamic torque monitoring |
- Verify gear backlash: 0.10-0.15ມມ (measure at 3 positions 120° apart)
Post-Installation Verification
-
Leak Testing
- Conduct 30min pressure test at 400kPa (max allowable drop: 25kPa)
-
Functional Check
- Run through all gear ranges 50x at 1500rpm
- Monitor temperature rise: ≤65°C after 15min operation
Critical Warnings
- Replace all circlips (mandatory for warranty validation)
- Maintain ambient temperature between 15-35°C during installation
- Initial oil replacement required after 300km break-in period
