Description

When you start hearing that dreaded rod knock or notice oil pressure dropping on your Ford New Holland diesel, it’s time for an engine rebuild – and that means new main bearings. This .020″ oversize main bearing kit from TISCO gives you the precision bearings you need to get that engine back to factory specs after machining the crankshaft journals. It’s the difference between a professional rebuild that lasts and throwing good money after bad.

What You’re Getting

Complete set of .020″ oversize main bearings for proper crankshaft support
TISCO quality construction built to handle diesel engine loads and temperatures
Precision-manufactured to restore proper oil clearances after crankshaft machining
Direct replacement bearings sized for rebuilt Ford New Holland diesel engines

Built for Real Farm Work

Ford New Holland diesel engines power everything from compact utility tractors to big row-crop machines that run thousands of hours each season. Whether you’re rebuilding a 3-cylinder engine from a 4000 series or working on a larger powerplant, these bearings are designed to handle the constant loads, heat cycles, and vibration that farm engines face daily.

Made to Last

Diesel engines are tough on bearings – high compression, heavy loads, and long operating hours demand quality components. These TISCO bearings use materials and construction designed specifically for agricultural diesel applications. The .020″ oversize dimension compensates for crankshaft machining, restoring proper oil film thickness and bearing life.

Good to Know

This kit requires a machined crankshaft with journals turned .020″ undersize. Have your crank checked by a machine shop before ordering to confirm the actual size needed. During assembly, check bearing clearances with Plastigage and follow proper torque specifications. Clean assembly and proper oil priming are critical for bearing life in a fresh rebuild.
