Description
When you’re doing an engine rebuild on your Ford tractor, getting the bearing clearances right is everything. If your crankshaft has been turned .040″ under, you need bearings that match those specifications exactly. These TISCO main bearings are manufactured to precise tolerances so your freshly machined crank will have the proper oil clearance and run smooth for years to come.
What You’re Getting
- Complete main bearing set sized .040″ under standard for turned crankshafts
- Precision-manufactured to OEM specifications for proper oil clearance
- High-quality materials that handle the stress of farm work
- Direct replacement during engine overhaul – no modifications needed
- Complete set covers all main bearing positions in your Ford engine
Built for Real Farm Work
These bearings are designed for Ford tractor engines that have been machined during rebuild. When your engine shop turns the crankshaft to clean up wear or damage, the journals end up smaller than original. That’s where these undersized bearings come in – they restore the proper clearances so oil pressure stays where it should be and everything runs like it’s supposed to.
Made to Last
TISCO builds these bearings to handle the demands of agricultural work. They’re constructed with materials that resist wear and maintain proper oil film thickness even under heavy loads. Whether you’re pulling a plow through tough ground or running a PTO-driven implement all day, these bearings will keep your rebuilt engine running strong.
Installation Notes
These are precision parts that require careful installation during engine assembly. Make sure your machine shop measures bearing clearances with Plastigage before final assembly – proper clearance is critical for long engine life. Keep everything clean during assembly and use the torque specifications from your service manual when tightening the main bearing caps.
