Additional information

This engine crankcase kit forms the main body of the engine and supports critical internal components such as the crankshaft and bearings. Part number 951-11249 helps keep engine oil sealed inside the block while maintaining proper alignment of moving parts.

Crankcase damage can show up as oil leaks, excessive vibration, abnormal engine noise, or internal component misalignment. In severe cases, the engine may seize, lose oil rapidly, or fail to run properly due to loss of structural support.

Disconnect the spark plug wire before starting the repair to prevent accidental engine startup. Internal engine components can be heavy and precisely aligned, so handle the crankcase carefully and follow proper torque and assembly procedures during installation.
