Cummins M11 Connecting Rod Catalog

The connecting rod system is one of the most critical assemblies in the Cummins M11 engine. Responsible for linking the piston to the crankshaft, connecting rods transfer combustion energy into rotational force. To ensure strength, durability, and smooth operation, every connecting rod requires precision-fit bushings and high-quality bearing sets. Diesel Pro Power supplies a full range of connecting rod components designed for the Cummins M11, as well as compatible engines including the Cummins L10, ISM, and QSM platforms.

With over 40,000+ satisfied customers worldwide, Diesel Pro Power provides marine and industrial operators with dependable OEM-grade and aftermarket components that keep Cummins engines running at peak efficiency.

Bearing Sets for Cummins M11 Connecting Rods

Connecting rod bearings are essential for reducing friction and maintaining oil film integrity between the rod and crankshaft journal. Diesel Pro Power offers a range of bearing sets engineered to meet Cummins specifications, ensuring proper fitment and reliable service life.

Standard Bearing Sets

Standard size connecting rod bearings are designed for engines that have not required crankshaft grinding or resizing. These bearings feature precision-machined surfaces to maintain the correct oil clearance, supporting stable lubrication under heavy marine and industrial loads.

• Designed for Cummins M11, L10, ISM, and QSM engines

• Includes both upper and lower bearing halves to service one connecting rod

• Provides excellent wear resistance and durability under continuous use

Oversize Bearing Sets

When crankshafts are machined undersize during a rebuild, oversize connecting rod bearings restore proper clearance. Diesel Pro Power supplies multiple oversize options to match varying degrees of crankshaft regrinding.

0.010" Oversize Bearings

• Fits Cummins M11, L10, ISM, and QSM engines

• Ideal for crankshafts ground 0.010" undersize

• Ensures consistent lubrication film thickness for extended engine life

0.020" Oversize Bearings

• Designed for Cummins M11, L10, ISM, and QSM engines

• Recommended for crankshafts ground 0.020" undersize

• Provides the same strength and reliability as standard bearings, with compensation for additional crankshaft wear

Oversize bearings are a vital solution during rebuilds, ensuring that connecting rods remain perfectly aligned with the crankshaft journals after machining.

Cummins M11 Connecting Rod Bushings

The connecting rod bushing, also known as the wrist pin bushing, is a key component that allows the piston pin to articulate smoothly inside the rod. High-quality bushings minimize friction, reduce wear, and prevent noise or vibration caused by piston pin movement.

• Precision-engineered for Cummins M11 and L10 engines

• Manufactured from premium materials to withstand high compression and load stress

• Helps extend piston and pin life by maintaining accurate clearances

• Easy to install during rod service or complete overhaul

Regular inspection and replacement of connecting rod bushings are recommended during major engine rebuilds to prevent premature wear and to maintain optimal piston operation.
