1. Pre-Installation Preparation
Required Tools & Materials
- 50T hydraulic floor jack with safety lock
- 1/2" drive torque wrench (80-300Nm range)
- LOCTITE 263 high-strength threadlocker
- Molybdenum disulfide grease (NLGI Grade 2)
Vehicle Preparation
❶ Disconnect negative battery terminal
❷ Engage parking brake and chock rear wheels
❸ Tilt cabin to 45° position using hydraulic support system
2. Removal Procedure
Шаг 1: Disassembly Sequence
- Remove 8x M16 flange nuts (120Крутящий момент) from pivot brackets
- Detach hydraulic tilt cylinder linkage
- Mark alignment positions with paint pen for reassembly reference
Шаг 2: Shaft Extraction
- Apply controlled heat (150-200° C.) to housing using induction heater
- Use press-fit tool (PN HT-5512) with 10° alignment tolerance
- Monitor extraction force (max 18T) to prevent housing deformation
3. New Assembly Installation
Critical Alignment Parameters
| Measurement |
Спецификация |
| Shaft parallelism |
≤0.15mm/m |
| End play |
0.05-0.15мм |
| Radial clearance |
0.02-0.05мм |
Installation Process
❶ Clean mating surfaces with acetone (Iso 11158 стандарт)
❷ Apply 1mm thick grease layer to bronze bushings
❸ Press-fit using guided installation tool (3-5T gradual force)
❹ Verify smooth rotation (0.8-1.2N·m rotational resistance)
4. Post-Installation Verification
Torque Specifications
| Component |
Torque Value |
| Pivot bolts |
280Nm ±5% |
| Locknuts |
160Nm + 45° turn |
| Bracket fasteners |
180Nm |
Functional Testing
- Complete 5 full tilt cycles (0°→45°→0°)
- Check for abnormal noise (<75dB at 1m distance)
- Measure hydraulic pressure drop (≤15% baseline)
5. Maintenance Requirements
- Initial re-grease after 500km operation
- 15,000km service interval with 30g grease replenishment
- Replace if axial play exceeds 0.8mm
