This component is the rear crankshaft seal housing, which encloses and seals the crankshaft's rear main bearing to prevent oil leakage from the engine. It is manufactured to meet stringent material and dimensional standards, ensuring a reliable seal that surpasses the performance of a worn or damaged housing. Operators may notice persistent oil drips from the rear of the engine, a noticeable drop in oil level, or a burning oil smell if this housing begins to fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Oil leaks originating from the rear of the engine are the first indication of a failing seal housing. If left unaddressed, the leaks will worsen, leading to significant oil consumption and potential lubrication issues. Continued operation with a compromised seal can lead to bearing damage and premature engine wear.
Ensure the crankshaft sealing surface is perfectly clean and free of any nicks or burrs before installation. Avoid overtightening the housing bolts, as this can distort the housing and compromise the seal.
Inspect the crankshaft rear main bearing and the rear main seal for wear or damage when replacing the housing.
