main bearing

The larger engine was modified to have only four rather than eight main bearings.

The 2.5 engine also features five main bearings and eight overhead valves.

The drive shaft's main bearing was also enlarged to 550 mm.

This engine had four main bearings and can be identified by the three core plugs on the side of the block.

These were cast iron engines, and used just three main bearings.

My men will have completed the re-assembly of the main bearing by noon today.

The Gen-3 crankshafts had 7 main bearings (increased from 4).

The number of main bearings was increased to four.

This was due to the tight tolerances of the engine main bearings.
