When your Ford or New Holland tractor’s engine starts knocking or losing compression, worn connecting rod bearings are often the culprit. These precision bearings keep the connecting rods properly positioned as they transfer power from the pistons to the crankshaft thousands of times per minute. If your engine’s been running with low oil pressure or you’re planning a rebuild after years of hard work, .040″ undersize bearings are exactly what you need to restore tight clearances on a machined crankshaft.
What You’re Getting
- Precise .040″ undersize dimensions match common crankshaft machining specifications
- High-quality TISCO construction with multi-layer design for superior durability
- Engineered bearing material handles heavy loads and high temperatures
- Direct replacement for worn bearings during engine overhaul or rebuild
- Proper oil clearances restore compression and eliminate bearing knock
Built for Engine Rebuilds
This connecting rod bearing is designed for Ford and New Holland tractor engines where the crankshaft has been machined .040″ undersize to remove scoring or wear. Whether you’re rebuilding a reliable workhorse that’s seen decades of field service or refreshing an engine after a bearing failure, these undersized bearings restore the precise clearances your engine needs to run smoothly and develop full power.
Made to Last
TISCO bearings use proven multi-layer construction with a steel backing, copper-lead intermediate layer, and protective overlay. This design handles the constant hammering of combustion forces while maintaining the oil film that prevents metal-to-metal contact. The materials resist fatigue and wear even under heavy loads during plowing, harvesting, or PTO work.
Installation Notes
Always verify your crankshaft has been machined .040″ undersize before installation – standard bearings won’t work on machined journals. Check rod side clearance and crankshaft endplay during assembly. Proper torque specifications and assembly lube are critical for bearing life. If you’re not experienced with engine rebuilds, this job is best left to a qualified mechanic who can ensure proper clearances and alignment.
