Connecting Rod Bearing Set (0.25 Undersize) οΈ
This precision bearing set is used between the connecting rod and the crankshaft journal. It is needed when the engine has
been rebuilt and the crankshaft is re-ground, so the oil clearance stays correct for a stable oil film. The 0.25 undersize
helps restore factory-like fit after machining, keeping the bottom end smooth and quiet.
How it works βοΈ
The bearing shells clamp inside the rod and cap, forming a round surface for the crank pin to spin on. Engine oil is fed
through passages to create a thin lubricating layer that prevents metal-to-metal contact. Correct clearance supports load,
controls heat, and maintains oil pressure at higher RPM.
If the bearing is worn or damaged
A failing rod bearing can cause knocking under load, falling oil pressure, and metallic debris in the oil. If ignored, the
journal may score, the rod can overheat and seize, and severe cases may lead to catastrophic engine failure.
Why replace it now β
- Restores correct crank-to-rod clearance after regrind
- Improves oil control, reduces noise, protects the crankshaft
- Essential for reliable rebuild and long service life
