This crankshaft seal is designed to prevent oil from leaking out of the engine at the crankshaft's rear main bearing, maintaining proper lubrication and oil pressure within the engine. Manufactured to meet rigorous OEM standards, it offers superior sealing performance and durability compared to a worn or brittle seal that has lost its elasticity. Operators may notice oil leaks around the transmission bell housing, a burning oil smell, or a drop in oil pressure if this seal fails.
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.
The first sign of a failing crankshaft seal is typically an oil leak originating from the rear of the engine, often visible on the transmission bell housing. If left unaddressed, the leak will worsen, potentially leading to a significant loss of engine oil and reduced oil pressure. Continued operation with a severely leaking seal can result in engine bearing damage due to insufficient lubrication.
Carefully inspect the crankshaft surface where the seal rides for any nicks or scoring that could compromise the new seal's integrity. Ensure the seal is installed perfectly square to avoid premature wear or leaks.
When replacing the crankshaft seal, it is essential to inspect the condition of the rear main bearing and the crankshaft itself for any signs of wear or damage.
