362-8853 Crankshaft Seal — Cat 3306

This crankshaft seal is essential for preventing oil from leaking out of the engine crankcase along the crankshaft, maintaining proper lubrication and oil levels. Manufactured to meet stringent OEM quality, it provides a reliable seal, unlike worn or brittle seals that allow oil to escape. Operators may notice oil drips or puddles under the engine, a burning oil smell, or a drop in oil pressure 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

The first sign of a failing crankshaft seal is typically visible oil leakage around the crankshaft pulley or flywheel housing. If ignored, the leak will worsen, potentially leading to significant oil loss and a low oil level warning. Prolonged operation with a leaking crankshaft seal can result in engine lubrication failure and severe internal damage.

Installation Tip

Ensure the crankshaft surface where the seal rides is clean and free of nicks or burrs before installation. Use a proper seal driver to install the seal squarely and avoid cocking it, which can cause immediate leakage.

Service Note

Inspect the crankshaft for scoring or wear, and check the front or rear engine mountings for damage when replacing the crankshaft seal.
