Description

When you hear that knocking sound coming from the engine compartment or notice oil pressure dropping, worn connecting rod bearings are often the culprit. These bearings take a beating connecting your pistons to the crankshaft, and when they wear out, your whole engine suffers. This .020 oversize bearing gets your Allis Chalmers back to smooth, quiet operation.

What You’re Getting

Individual connecting rod bearing sized at .020 inch oversize for rebuilt cranks
Precise tolerances that restore proper oil clearances and pressure
Durable bearing material that handles the constant stress of engine operation
Direct replacement for worn bearings during engine rebuilds or major repairs

Built for Reliable Farm Work

This bearing fits the dependable engines in your Allis Chalmers D10, D12, D14, and D15 tractors. These workhorses were built for everything from field work to loader duty, and their engines are known for running strong when maintained properly. Whether you’re cultivating, planting, or running the PTO, these bearings keep everything spinning smooth.

Made to Last

Farm engines run hard and long, so these bearings are manufactured to handle the constant reciprocating loads and heat cycling that comes with agricultural work. The bearing material provides excellent wear resistance while maintaining the oil film needed for proper lubrication throughout the engine’s operating range.

Good to Know

This is a .020 oversize bearing, which means it’s designed for crankshafts that have been turned down .020 inch during a rebuild. Make sure your crank journals have been properly machined to this size before installation. Individual bearings let you replace just what’s needed rather than buying a complete set if only one cylinder needs attention.
