Installation Tools & Preparation
-
Required Tools
- Hydraulic press (10-20T capacity)
- Torque wrench (50-150Nm range)
- Wire brush and degreaser
- LOCTITE 243 threadlocker
-
Vehicle Preparation
- Secure cabin in tilted position using hydraulic support system
- Clean mounting surfaces with acetone (remove grease/rust)
Removal Process
Step 1: Old Bushing Extraction
❶ Apply penetrating oil (WD-40) to corrosion areas
❷ Use hydraulic press to push out worn bushing
- Maintain alignment within 2° deviation
- Heat surrounding area to 80-100°C if stuck
Step 2: Surface Preparation
| Operation |
Specification |
| Bore inspection |
Measure ID with caliper (φ50mm ±0.05mm) |
| Debris removal |
Use compressed air (0.6-0.8MPa pressure) |
New Bushing Installation
Step 1: Lubrication & Alignment
- Coat inner surface with molybdenum disulfide grease
- Align bushing oil groove with chassis lubrication point
Step 2: Press-Fit Procedure
❶ Use press adapter sleeves to protect bushing edges
❷ Apply gradual pressure (max 15T force)
❸ Verify flush seating (gap <0.1mm perimeter)
Post-Installation Verification
-
Torque Specifications
| Component |
ຄຸນຄ່າ |
| Pivot bolt |
120-130Nm |
| Lock nut |
90Nm + 30° turn |
-
Functional Check
- Confirm smooth rotation (0.5-2.5N·m rotational torque)
- Test full cabin tilt cycle 3x without binding
-
Stress Relief Protocol
- Loosen/re-torque all suspension arm bolts at ride height
- Complete four-wheel alignment within 50km
Critical Maintenance Note
- Re-grease through zerk fitting every 15,000km
- Replace if radial play exceeds 1.5mm
