2P6224 Seal Gp-Crankshaft — Cat 120G 12G

This is a crankshaft seal group designed to prevent oil leakage from the rear of the engine crankshaft. Manufactured to meet stringent OEM quality standards, it provides a reliable seal that prevents oil loss and contamination, unlike a worn or cracked seal. Operators may notice oil puddles under the engine, a burning oil smell, or a drop in oil level when this seal begins to fail.

Installation & Application Notes

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.

Failure Symptoms

Visible oil leaks from the rear of the engine, often forming puddles, are the first sign of a failing crankshaft seal. If left unaddressed, the oil level can drop significantly, leading to increased friction and potential engine damage. Continued leakage can also contaminate the clutch or flywheel, requiring additional repairs.

Installation Tip

Carefully inspect the crankshaft surface for any nicks or rough spots that could damage the new seal during installation. Ensure the seal is installed perfectly square to avoid premature failure.

Service Note

Inspect the rear main bearing and flywheel when replacing the crankshaft seal.
