When you’re rebuilding an International Harvester engine and the machine shop measures your crank journals at -.002 undersized, you need bearings that match those exact specifications. This TISCO main bearing set is precision manufactured to handle the reduced journal size while maintaining proper oil clearances, giving you the tight tolerances you need for reliable operation.
What You’re Getting
- Complete main bearing set specifically sized for .002 undersized crankshaft journals
- TISCO quality construction with proper oil clearances for rebuilt engines
- Engineered to handle the heavy loads and high operating hours typical of farm tractors
- Direct replacement that fits without modifications to your engine block or crankshaft
Built for Real Farm Work
This bearing set is designed for International Harvester tractors that have had their crankshafts machined during engine rebuilds. When you’re putting serious hours on your tractor during planting, harvest, or daily chores, these bearings need to handle everything from long days in the field to heavy loader work around the farmyard.
Made to Last
TISCO builds these bearings to withstand the constant loads and temperature cycling that comes with agricultural use. The precision manufacturing ensures proper fit with your machined crankshaft, while the bearing material is formulated to handle the demanding conditions of farm engine operation season after season.
Good to Know
Installing undersized bearings requires precise measurement and proper torque specifications – don’t guess on clearances when you’re this deep into an engine rebuild. Make sure your oil pump and passages are clean, and use quality engine oil with the correct viscosity. It’s also smart to check your connecting rod bearings while you’re rebuilding the bottom end.
