Diagram ref no 42.

Installed at the lower section of the engine crankcase, the gasket seals the oil sump plate and helps prevent oil leakage from the engine lubrication system. Proper sealing is critical for maintaining correct oil retention, preventing contamination, and ensuring reliable engine lubrication. The gasket is commonly replaced during oil changes, sump plate servicing, or engine rebuild work.

Function
•  Seals oil sump plate and oil strainer assembly
•  Prevents engine oil leakage
•  Maintains proper oil retention within crankcase
•  Supports reliable engine lubrication system operation
•  Resists oil exposure and engine heat

Over time, sump gaskets can harden, compress, or deteriorate due to constant exposure to engine oil and heat. A worn gasket may cause oil leaks, reduced sealing performance, and contamination around the sump area. Replacing the gasket during servicing helps maintain proper oil sealing and prevents oil loss from the lubrication system.

When to replace
•  Oil leakage around sump plate area
•  During oil strainer or sump plate servicing
•  Hardened, cracked, or compressed gasket material
•  During engine rebuild or maintenance work
•  Preventative replacement during oil service
