The marine engine main bearing cap holds the main bearings and crankshaft in the block. It is used on marine propulsion and auxiliary engines on workboats, supply vessels, tugs and barges.
The cylinder block and head form the main structure of the engine, holding the liners, valves, crankshaft and camshaft in precise alignment.
Why it matters
Cracks, warping or worn liners lead to compression loss, coolant leaks and oil consumption, and usually require replacement parts during an overhaul.
Common signs it needs replacing
- Loss of compression
- Visible cracks or casting damage
- Blow-by and high oil consumption
- Coolant in the oil or oil in the coolant
How to order the right part
- Share the engine make, model and serial number from the engine nameplate.
- Send a clear photo of the old part and any numbers cast or stamped on it.
- Tell us the application (for example generator set, compressor, pump or vessel) and running hours.
- Ask about available options, condition (new or reconditioned) and lead time.
