FAQ

Q: Will this HD-2294 cushion fit my Komatsu PC50-4 model?
A: Yes, the HD-2294 is a direct replacement for the PC50-4. It fits both the left and right engine mounts. We recommend visually comparing the shape of your old mount with the product image to confirm the “ear” orientation.

Q: Do I need to replace both engine cushions at the same time?
A: While not mandatory, we strongly recommend replacing both engine mounts (left and right) simultaneously. This ensures even wear, balanced vibration dampening, and prevents premature failure of the new mount due to an uneven load from the old one.

Q: What is the torque specification for the mounting bolts?
A: For the Komatsu 4D84 engine, the standard torque for the engine mount through-bolts is typically 65-75 Nm (48-55 ft-lbs). However, always consult your specific machine’s service manual for the exact torque and tightening sequence to avoid damaging the rubber isolator.
