Description
When your engine starts knocking or you’re seeing metal shavings in the oil, it’s time to face the facts—those connecting rod bearings are worn out. An engine rebuild might sound daunting, but starting with quality .020″ undersize bearings like these gets you back to reliable power. These TISCO bearings are designed to work with crankshafts that have been turned .020″ undersize during machine shop work.
What You’re Getting
- Precision-manufactured bearings sized for .020″ undersize crankshaft journals
- High-quality bearing material that handles the loads and heat of diesel operation
- Proper oil clearances when installed on machined crankshafts
- Direct replacement design that fits like the originals
Built for Engine Rebuilds
These bearings are specifically made for Ford and New Holland tractor engines that have had their crankshafts machined. When an engine gets rebuilt, the machine shop typically turns the crank journals down .010″, .020″, or .030″ to clean up wear and scoring. These .020″ undersize bearings give you the proper fit and oil clearance on those machined surfaces.
Made to Last
Engine bearings take tremendous loads every time that piston fires, and cheap bearings won’t cut it when you’re putting serious hours on your tractor. These TISCO bearings use quality bearing material that resists fatigue and maintains proper oil film thickness under the demanding conditions of agricultural work.
Installation Notes
These bearings require a crankshaft that’s been machined .020″ undersize—they won’t work on a standard crank. Your machine shop will verify the journal size and bearing clearances during assembly. Make sure to follow proper torque specs and use assembly lube during installation to prevent dry startup damage.
