The crankcase often forms the upper half of the main bearing journals (with the bearing caps forming the other half), although in some engines the crankcase completely surrounds the main bearing journals.

The crankcase is the main housing of an internal combustion engine, serving as the structure for the moving parts that convert combustion into rotational motion.

The crankcase is an enclosed chamber or housing that surrounds and contains the crankshaft of the engine. It's the largest part of the engine but must be designed to be strong and light.

A crankcase is the housing for the crankshaft in a reciprocating internal combustion engine. In most modern engines, the crankcase is integrated into the engine block.

The upper half of the crankcase is made by the lower portion of the engine block and the lower half of the crankcase is connected to the upper half to form a crankcase cavity.

Mounted between the engine block and the oil pan, the crankcase supports the crankshaft, allowing it to spin freely while transmitting power (torque) from the engine.

Dec 29, 2024 · A crankcase is like a protective container in the middle of an engine. It holds crucial engine parts like the crankshaft and lubricates them with oil to reduce friction and wear.

Sep 4, 2025 · A crankcase is actually just a cover for your engine, situated between the engine block. It has been constructed in order to cover and protect some of the most vital components of your engine.

May 23, 2024 · An intrinsic component of an internal combustion engine, the crankcase is a drilled metal frame that houses several parts, notably the crankshaft. Its main universal function is to shield the …
