Engine bearing set for 139QMB/QMA
BT12281
New
This bearing set contains all the relevant bearings found within the engine. A complete kit, at a low price. Crank main bearings not included. Not available as single items, owing to the huge risk on the timing chain sit of the crank when installing. Where new main bearings are required, we recommend buying a new crank. The bearings come pre-installed and there is no danger of damaging the engine.
