A low oil pressure reading in a machine running a Cummins QSB4.5 Engine is a severe problem, often leading to engine damage. Causes typically include low oil level, a failed oil pump, or excessive bearing clearance (worn main or connecting rod bearings).
**Solution:** Immediately check the oil level. If the level is correct, the issue is likely internal. Worn main bearings (main bearing set) or connecting rod bearings (connecting rod bearing) cause oil to leak out too fast, dropping pressure. Replacement requires full engine access. If the bearings are worn, a complete rebuild is recommended, ensuring our high-quality genuine quality engine parts are used, including new thrust washers and oil pump to fully restore system integrity for reliable earthmoving equipment maintenance.
