This is a Front Gear Cover Gasket designed to seal the front gear housing on Cummins 6C8.3 engines used in Hyundai R290Lc-7 and Volvo Ec240 excavators.

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 front gear cover gasket is typically a visible oil leak originating from the front of the engine, often noticed on the ground under the machine. If left unaddressed, the leak will likely worsen, leading to increased oil consumption and potential oil starvation. Continued operation with a significant leak risks damage to engine components due to insufficient lubrication.

Installation Tip

Thoroughly clean and inspect both sealing surfaces for any nicks or damage before applying the new gasket. Avoid overtightening the gear cover bolts, as this can crush the gasket and lead to premature failure.

Service Note

Inspect the front crankshaft seal and the timing gears for wear when replacing the front gear cover gasket.
