Connecting Rods & Related Components for Cummins L10 Engines

The connecting rod is one of the most critical components within the Cummins L10 engine, responsible for transferring the linear force of the piston into rotational power at the crankshaft. This constant movement subjects the connecting rods, bearings, and bushings to high loads and friction. Over time, these parts naturally wear, and replacing them with high-quality components is essential for maintaining proper lubrication, compression, and smooth operation of your L10 engine.

At Diesel Pro Power, we provide a full range of connecting rod components for Cummins L10 engines, trusted by over 40,000 satisfied customers worldwide. Whether you are completing a full overhaul or replacing individual wear items, our catalog ensures you have access to the most reliable solutions.

Bearing Sets for Cummins L10 Connecting Rods

Standard Bearing Sets

Standard-size connecting rod bearings are designed for engines where the crankshaft journals have not been machined undersize. These bearings restore proper clearance between the connecting rod and crankshaft, ensuring that oil pressure is maintained, friction is reduced, and the engine continues to operate smoothly.

Key benefits of standard bearings:

• Restores OEM-level fit and performance

• Helps maintain correct oil film thickness

• Ideal for engines that have not undergone crankshaft machining

Oversize Bearing Sets – 0.010"

In cases where the crankshaft has been machined due to wear or scoring, oversize bearings are required to fill the additional clearance. The 0.010” oversize bearing set for the Cummins L10 ensures that after machining, the connecting rod remains properly aligned with the crankshaft journal.

Benefits of oversize 0.010” bearings:

• Ensures precise fit after crankshaft machining

• Extends the usable life of your crankshaft

• Protects against uneven wear and premature failure

Oversize Bearing Sets – 0.020"

For engines requiring more extensive crankshaft repair, the 0.020” oversize bearings are the solution. These bearings restore critical clearance after deeper machining, allowing operators to bring heavily used Cummins L10 engines back into reliable service.

Advantages of oversize 0.020” bearings:

• Provides fit for heavily worn or reconditioned crankshafts

• Restores oil clearance for effective lubrication

• Delivers long-term durability under high loads

Cummins L10 Connecting Rod Bushings

The connecting rod bushing plays an equally vital role by supporting the piston pin (gudgeon pin) where it attaches to the connecting rod. Over time, bushings wear down due to the constant reciprocating motion, leading to increased piston play, noise, and risk of imbalance.

Replacing the connecting rod bushing ensures:

• Smooth piston pin rotation

• Reduced friction and heat buildup

• Prevention of piston knock or failure under load

The L10 connecting rod bushing is manufactured with durable alloys to withstand heavy-duty applications and provide long-lasting reliability.

Why Replacing Bearings and Bushings Matters for L10 Engines

A worn connecting rod bearing or bushing can lead to serious engine issues if left unchecked. Symptoms of wear may include:

• Knocking or tapping sounds from the engine

• Fluctuating or low oil pressure

• Excessive vibration at higher RPMs

• Premature wear on crankshaft journals

By replacing these wear items during maintenance or overhaul, operators can prevent costly downtime and extend the service life of their Cummins L10 engines.

Applications of Cummins L10 Connecting Rod Components

The Cummins L10 is widely used in industrial and marine applications, where long service intervals and reliability are essential. Typical uses include:

• Marine propulsion engines for commercial vessels

• Industrial power generation

• Construction and heavy equipment

• Oilfield and mining machinery

Ensuring that the connecting rods, bearings, and bushings are in top condition guarantees that these engines can withstand high loads, extended operating hours, and demanding environments.
