21779548 Front Crank Seal — Volvo

This is a front crankshaft oil seal designed to prevent lubricant from escaping the engine's crankcase at the front pulley end for Volvo and Renault engines. It is constructed from durable materials to meet OEM specifications, providing a reliable seal unlike a hardened or cracked seal that allows oil leaks. Observable symptoms of a failing front crank seal include oil drips or wetness around the front of the engine, particularly near the crankshaft pulley, and a potential drop in oil level.

Fitment: Renault Trucks Crankshaft Oil Seal

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 or wetness around the crankshaft pulley are the primary indicators of a failing front crank seal. If left unaddressed, the oil leak can worsen, leading to a significant loss of engine oil. This can result in insufficient lubrication, potentially causing severe engine damage due to overheating and friction.

Installation Tip

Ensure the crankshaft snout is clean and free of burrs before installing the new seal. Do not use excessive force or pry tools directly against the seal lip, as this can cause damage.

Service Note

Inspect the crankshaft pulley and the crankshaft snout for any damage or wear that could compromise the new seal's effectiveness.
