EBPMR1001

MOTOR MOUNT BUSHING

This is a motor mount bushing used to secure the engine to the truck's frame. It acts as a cushion to absorb engine vibrations and prevent metal-on-metal contact. You typically replace these when the rubber deteriorates, cracks, or collapses, leading to excessive engine movement, vibration in the cab, or misalignment. This part is an aftermarket cross-reference for the Peterbilt MR1001 engine mount system.
