FAQ

Q1: Will these bearings fit my Cummins QSM11 engine from a 2005 excavator?
A: Yes, the 3801152 main bearings and 3801153 connecting rod bearings are designed for all QSM11 engine variants, including those used in excavators, regardless of the year (post-2000). Always verify your existing part number before installation.

Q2: Do I need to replace both main and connecting rod bearings at the same time?
A: While not strictly required, it is highly recommended to replace both sets during an engine rebuild to ensure even wear and optimal oil clearance. This prevents future bearing failure and extends engine life.

Q3: What is the proper installation procedure for these bearings?
A: Installation should be performed by a qualified mechanic. Ensure the bearing surfaces are clean and lubricated with engine oil during assembly. Use a torque wrench to tighten the main bearing and connecting rod bolts to the manufacturer’s specifications (refer to your service manual). Never reuse old bolts.
