FPCY2507058 — Standard Crankshaft Main Bearing Set 7420867178 For Volvo Engine D11 Truck Fm Fm9 Fmx

This crankshaft main bearing set is essential for supporting the rotating crankshaft within the engine block, minimizing friction and wear. Manufactured to precise tolerances using high-quality bearing materials, it offers superior durability and load-carrying capacity over worn bearings that have developed excessive clearance. Operators may observe increased engine noise, particularly a deep knocking sound from the lower end, and potentially a drop in oil pressure when these bearings begin 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 initial symptom of failing main bearings is often an increase in low-frequency knocking or rumbling noises from the bottom of the engine, especially under load. As wear progresses, this noise becomes more pronounced, and a significant drop in oil pressure may be observed. Continued operation with worn main bearings can lead to catastrophic crankshaft and block damage due to excessive movement and heat generation.

Installation Tip

Ensure the crankshaft and bearing bores are meticulously cleaned and free of any debris before installation. Never reuse old bearing cap bolts; always use new ones to ensure proper clamping force.

Service Note

Inspect the crankshaft journals for any signs of scoring or ovality, and check the connecting rod bearings for wear.
