Cummins N14 Engine Parts – Connecting Rod Components

The Cummins N14 is one of the most trusted heavy-duty diesel engines ever produced, known for its durability, fuel efficiency, and adaptability across marine, industrial, and commercial power applications. To keep this legendary engine performing at its best, maintaining the integrity of the connecting rod assembly is essential. The connecting rod is the critical link between the piston and the crankshaft, transferring combustion energy into rotational power.

At Diesel Pro Power, we provide a full catalog of connecting rod parts for Cummins N14 engines, including bearing sets, bushings, and bolts. All components are manufactured to OEM specifications and ready for installation. With over 40,000 satisfied customers worldwide, Diesel Pro Power is the trusted source for Cummins engine parts delivered fast and reliably.

Bearing Sets for Cummins N14 Connecting Rods

Connecting rod bearings are vital for reducing friction and supporting smooth movement between the connecting rod and the crankshaft journal. Over time, bearings wear down due to high loads, oil contamination, or improper lubrication. Replacing them at the correct intervals prevents costly engine damage.

Standard Bearing Set for Cummins N14 Engines

The standard-size bearing set is designed for rods that have not been machined or resized. Each set includes an upper and lower shell to service one connecting rod. These bearings restore proper oil clearance and protect against metal-to-metal contact, ensuring a smooth rotation and long crankshaft life.

Oversize 0.010" Bearing Set for Cummins N14

For connecting rods and crankshaft journals that have been ground undersize by 0.010", this oversize bearing set restores the correct fitment. Precision-machined to maintain oil film integrity, these bearings allow engines with worn journals to be rebuilt to factory specifications without replacing the crankshaft.

Oversize 0.020" Bearing Set for Cummins N14

When additional wear requires a larger undersize grind, the 0.020" oversize bearing set provides the proper clearance. Like all Diesel Pro Power bearings, these are manufactured with premium materials for strength, fatigue resistance, and long service life.

Why Choose Diesel Pro Bearings?

• Manufactured to OEM specifications

• Designed for heavy-duty Cummins N14 applications

• Helps restore oil clearance and prevent premature wear

• Available in multiple sizes to fit rebuild requirements

Cummins N14 Connecting Rod Bushings

The connecting rod bushing supports the piston pin, allowing the rod and piston assembly to move freely under extreme combustion forces. Over time, bushings can wear down, leading to excessive clearance, piston slap, and reduced efficiency.

At Diesel Pro Power, our Cummins N14 connecting rod bushings are precision-machined for proper pin fitment. Each rod requires one bushing, which can be pressed into the small end of the rod during an overhaul. Replacing bushings during a rebuild ensures smooth piston travel and eliminates risks of pin scoring or rod damage.

Key Benefits:

• Designed for exact Cummins N14 specifications

• Precision-machined bronze alloy for durability

• Extends piston and rod service life

• Essential for complete connecting rod rebuilds

Cummins N14 Connecting Rod Bolts

The connecting rod bolt is one of the most stressed fasteners in the entire engine. These bolts secure the connecting rod cap to the rod body, clamping the bearing shells tightly around the crankshaft journal. Failure of a connecting rod bolt can result in catastrophic engine damage.

Diesel Pro Power supplies heavy-duty connecting rod bolts specifically engineered for Cummins N14 engines. Each rod requires two bolts, and it is highly recommended that bolts be replaced during any overhaul or bearing service.

Key Benefits of New Rod Bolts:

• High-strength steel construction for fatigue resistance

• Maintains clamping force under extreme pressure

• Designed for N14 load specifications

• Ensures engine safety and reliability during operation
