Description

When you’re hearing that telltale knocking sound from the engine or notice your Allis Chalmers D-series tractor isn’t running as smooth as it used to, worn connecting rod bearings are usually the culprit. These precision bearings keep your pistons and crankshaft working together smoothly, and when they wear out, it’s time for a replacement to get your tractor back to reliable operation.

What You’re Getting

Individual TISCO connecting rod bearing manufactured to exact OEM specifications
0.010 inch oversize to accommodate normal engine wear and rebuild requirements
Precision-manufactured bearing surface that handles the constant stress of engine operation
Quality construction designed to withstand the heat and pressure cycles of gas engines

Built for Real Farm Work

This bearing fits the gas engines in Allis Chalmers D10, D12, D14, and D15 tractors – the reliable workhorses that handled everything from cultivating to hay making during their heyday. These tractors were built when things were made to last, and this bearing maintains that same standard of durability for your engine rebuild or overhaul.

Made to Last

TISCO manufactures these bearings to handle the demanding conditions inside your engine. The bearing material is formulated to work with proper oil pressure and lubrication, providing smooth operation while resisting wear from the constant reciprocating motion and combustion pressures that come with farm work.

Good to Know

This is an individual bearing, so you’ll need to order the quantity required for your specific engine rebuild. The 0.010 oversize specification means your crankshaft journals will need to be machined to the appropriate undersize during your engine overhaul. Always check your machine work tolerances and consult your engine rebuild manual for proper installation procedures.
