This is a set of front and rear crankshaft oil seals designed to prevent lubricant leakage from the engine's crankshaft. They are manufactured to meet stringent sealing standards, ensuring a reliable barrier against oil loss that is superior to worn or damaged seals. Operators may notice oil spots under the equipment, a persistent burning oil smell, or a noticeable drop in oil level if these seals 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.
The first sign of failure is typically a visible oil leak around the crankshaft pulley or flywheel area. If left unaddressed, the leak will worsen, leading to significant oil consumption and potential lubrication issues. Continued operation with a failing seal risks oil starvation to critical engine components.
Ensure the crankshaft sealing surface is perfectly clean and free of any burrs or imperfections before installation. Avoid using excessive force or improper tools, which can damage the seal lip during installation.
Inspect the crankshaft snout for wear or damage, and check the condition of the front and rear main bearings while the seals are being replaced.
