Fitment

✔ Fits Caterpillar 3406E and C15 diesel engines (standard main bearing set) — verify engine serial number to confirm compatibility before ordering.

Why Replace Main Bearings?

Main bearings are essential parts that support the crankshaft and absorb engine loads during operation. Excessive wear can lead to reduced oil pressure, noisy operation, and ultimately catastrophic engine failure if not addressed in time.
