Metal-rubber vibration isolator for securing engine and/or gearbox. It attenuates drivetrain vibration transferred to the chassis, stabilises alignment and reduces in-cab noise.
Tech note: Close variants exist; compare sleeve orientation and dimensions with the removed mount before purchase.
GX-AFTER delivers robust rubber compounds and precisely machined sleeves for long service in harsh conditions.
| Brand (Machine type) | Model |
|---|---|
| JCB (Backhoe loaders) | 2CX, 2DX, 3CX, 4CX |
| JCB (Telehandlers) | incl. 520-50, 520-55, 526-55, 526, 528-70, 528S, 530S, 525-50, 525 |
The list above is indicative. Compare part number and dimensions with your machine’s fitted mount.
1. Keep orientation
Align sleeve and seat as per original. Reversed fitment reduces damping efficiency.
2. Tighten in stages
Use even torque to avoid twisting rubber or delamination.
3. Inspect hardware
Replace corroded bolts/spacers; check for ovalised bores.
4. Post-install check
Run and load the machine; observe vibration and any movement of the power unit.
Do not install a mount with cracked rubber or corroded sleeves. Incorrect fitment may damage drivetrain mounts.
The mount carries engine/gearbox loads while filtering vibration. Wear quickly affects comfort and component longevity.
Don’t let vibration shorten component life — replace the mount before secondary damage occurs.
