This is a set of main and connecting rod bearings for Perkins 1004.42 and Volvo EW150C engines, critical for reducing friction and wear between rotating crankshaft and connecting rod components. Manufactured to precise tolerances and material specifications, these bearings ensure smooth operation and longevity, unlike worn bearings that can cause excessive play and noise. Symptoms of failing bearings include a distinct knocking sound from the engine, low oil pressure, and increased oil consumption.

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 most common initial symptom of failing main or connecting rod bearings is an audible knocking or rattling sound from the engine, particularly under load. If ignored, this noise will intensify, and oil pressure may drop significantly, leading to increased friction and heat. Continued operation risks severe crankshaft and connecting rod damage, potentially requiring a complete engine rebuild.

Installation Tip

Ensure crankshaft journals are perfectly clean and free of any burrs or imperfections before installing bearings. Never reuse old bearing shells, as they are designed for a single installation and wear pattern.

Service Note

Always inspect the crankshaft journals for scoring or wear, and check the oil pump and oil filter for debris when replacing engine bearings.
