Installation Tools & Preparação
-
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
Etapa 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
Etapa 2: Surface Preparation
| Operation |
Especificação |
| Bore inspection |
Measure ID with caliper (φ50mm ±0.05mm) |
| Debris removal |
Use compressed air (0.6-0.8MPa pressure) |
New Bushing Installation
Etapa 1: Lubrication & Alignment
- Coat inner surface with molybdenum disulfide grease
- Align bushing oil groove with chassis lubrication point
Etapa 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)
