2223910 Seal Gp-Crankshaft — Cat 120H 120H es

This is a crankshaft seal assembly designed to prevent oil leakage from the engine's crankshaft, maintaining proper lubrication and preventing contamination. It is constructed from high-quality sealing materials engineered to withstand engine temperatures and pressures, offering superior performance over a worn or cracked seal. Observable symptoms of failure include visible oil leaks around the crankshaft pulley or a low oil level warning, potentially leading to oil starvation if unaddressed.

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

The first sign of a failing crankshaft seal is typically a visible oil leak originating from the area of the crankshaft pulley. If the leak is ignored, it can lead to a significant loss of engine oil, potentially causing low oil pressure and damage to engine bearings. The ultimate risk is engine seizure due to insufficient lubrication.

Installation Tip

Carefully inspect the crankshaft surface for any nicks or imperfections that could damage the new seal lip. Ensure the seal is installed perfectly square to the crankshaft bore to prevent premature failure.

Service Note

Inspect the oil pan, oil pickup tube, and oil pump for any signs of blockage or damage.
