Description
Overview:
The Main Bearing Cover for Robin/Subaru EH12 engines is a precision-machined housing that supports and protects the crankshaft's main bearing. Typically manufactured from durable die-cast aluminium for strength with low weight, it helps maintain correct crankshaft alignment and sealing, ensuring smooth engine operation and long service life. This cover is an exact-form replacement to suit the EH12 engine used across construction and garden machinery such as compactors, generators, pumps, and mixers. Marked with OEM No. 252-11103-01 for accurate identification, it is engineered to match the original mounting points and clearances, aiding straightforward refitting during servicing or rebuilds. A sound bearing cover helps prevent premature wear, reduces vibration, and supports efficient lubrication control within the crankcase.
