This set provides main and connecting rod bearings, crucial for reducing friction and supporting the crankshaft within the Volvo D6E engine. Manufactured to precise tolerances, these bearings ensure proper oil clearance and withstand extreme operating pressures, unlike worn bearings that can lead to excessive play and engine noise. Symptoms of failing bearings include a persistent knocking sound from the engine, a significant drop in oil pressure, and potential engine seizure if ignored.
Always verify with serial number before ordering.

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.
A distinct knocking or rattling noise originating from the engine, particularly under load, is the first sign of bearing failure. As wear progresses, oil pressure will drop noticeably, and the noise will become more pronounced and constant. Continued operation risks severe crankshaft and block damage, leading to a complete engine rebuild.
Ensure all oil passages are completely clean and free of debris before installation; even a small particle can compromise the new bearing's function. Do not reuse old bearing cap bolts, as they may have stretched and will not provide adequate clamping force.
Inspect the crankshaft journals for any signs of scoring, wear, or out-of-roundness, and check the oil pump for proper pressure output.
