FPLJ2601264 — +0.25Mm Main Bearing &Amp; Thrust Set 4955856 For Cummins Engine B3.9 B4.5 B5.9 Isb Qsb4.5 Qsb5.9 Volvo Excavator Ec140

This main bearing and thrust set provides critical support for the engine's crankshaft, allowing it to rotate smoothly while absorbing axial thrust loads. Manufactured to precise tolerances, these bearings offer superior wear resistance and load-bearing capacity compared to worn or damaged components. Operators might observe increased engine noise, particularly knocking sounds, or a drop in oil pressure if 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

Increased engine noise, often described as a deep knocking or rumbling sound, is a primary indicator of worn main bearings. If ignored, this can progress to a significant loss of oil pressure, leading to accelerated wear on other internal engine components. Continued operation risks crankshaft seizure and severe engine damage.

Installation Tip

Thoroughly clean the crankshaft journals and bearing bores before installation to remove any debris. Ensure the correct bearing orientation and lubrication are applied before torquing the bearing caps.

Service Note

Inspect the crankshaft journals for scoring or wear, and check the oil pump and oil filter for any signs of metal debris.
