Professional Installation Required
Involves lifting the engine slightly — must be done by trained technicians using proper jacks and safety stands.
Never rely solely on hydraulic jack.
Support the Engine Properly
Use an engine support bar mounted to the chassis rails.
Remove only one mount at a time if possible.
Replace in Pairs When Necessary
If one rear mount is damaged, inspect all other engine supports.
Replace together to ensure balanced load distribution.
Align Before Final Tightening
Ensure mounting holes align perfectly before tightening bolts.
Misalignment causes stress and early failure.
Torque Bolts to Specification
Typically requires 100–150 Nm depending on thread size.
Under-tightening → loosening; Over-tightening → cracked bracket or stripped threads.
Inspect for Oil Contamination
Oil-soaked mounts lose elasticity — replace immediately if swollen or sticky.
Check for Cracks and Separation
Rubber tearing
Metal fatigue
Delamination between steel and rubber
Look for visible signs of:
Replace at first sign of damage.
Avoid Using Damaged Units
Do not install a cracked or deformed mount — risk of complete failure.
Use Genuine or High-Quality Replacements
Low-cost imitations often use inferior rubber compounds that harden quickly.
Storage Advice
Store upright in dry indoor environment.
Keep away from direct sunlight and ozone sources (e.g., motors).
