Immediate inspection required if any of these symptoms are present:
- Noticeable knocking or metal-to-metal impact noise from engine bay
- Increased vibration in steering wheel, seat, and cab floor
- Excessive engine fore-aft movement, increased shock during gear shifts
- Visible rubber cracking, deformation, delamination, or separation
- Engine position shift causing abnormal belt/hose wear
| Feature | Benefit |
|---|---|
| High-elasticity rubber | Effectively isolates engine vibration and reduces cab noise |
| Precision vulcanization process | High bonding strength between rubber and metal bracket, prevents delamination |
| OEM-standard dimensions | Direct bolt-on fitment without modification |
| Oil-resistant and anti-aging formula | Withstands engine bay high temperatures and oil contamination, extends service life |
| QC Item | Verification Method |
|---|---|
| Dimensional inspection | Caliper and CMM measurement against OEM drawing |
| Rubber hardness test | Shore durometer testing for damping performance |
| Rubber-to-metal bond strength | Tensile testing for vulcanization bond strength |
| Visual inspection | Visual check for cracks, porosity, and defects |
| Oil resistance test | Immersion testing for rubber oil resistance |
| Final inspection | 100% factory visual and dimensional inspection |
- Park vehicle on level ground, apply parking brake, chock wheels
- Support engine bottom with jack or engine hoist, ensure engine is stable
- Remove old mount bolts, take out old cushion
- Inspect metal bracket and mounting seat for cracks or deformation
- Install new cushion, torque bolts to specification (45-60 Nm / 33-44 ft-lbs)
- Slowly release engine support, verify cushion seated properly
- Start engine, check for normal vibration at idle and acceleration
Inspect engine mounting cushion every 60,000 km or 12 months. Preventive replacement recommended every 120,000 km. Replace immediately if rubber cracking, deformation, or abnormal vibration is detected.
