Description

When you’re rebuilding an old IH engine and you hear that telltale knocking from worn rod bearings, you know it’s time to get serious about the rebuild. Loose or worn connecting rod bearings don’t just make noise—they’ll destroy your crankshaft and turn a manageable rebuild into a major headache. This standard size rod bearing kit fits International Harvester’s 100 series, 200 Series, Super A-1 Series, Super AV-1 Series, and Super C Series tractors and gets those connecting rods back to proper clearances.

What You’re Getting

Complete set of standard size connecting rod bearings for a complete rebuild job
Precision-manufactured bearings that meet OEM specifications for proper fit and clearance
TISCO quality construction designed to handle the punishment that comes with farm work, built to keep running smooth even in demanding conditions
Direct replacement for worn factory bearings—no machine work needed on standard cranks

Built for Real Farm Work

This kit works on International Harvester’s 4-cylinder gas engines with 123 cubic inches of displacement, the workhorses that powered everything from Super A utility tractors to Super C row-crop machines. Whether you’re restoring a vintage tractor for the farm or getting an old reliable back to earning its keep, these bearings handle the loads and stresses of real agricultural work.

Made to Last

These bearings are built to handle the punishment that comes with agricultural equipment—constant rotation under load, vibration, temperature swings, and all the dirt and debris that farm work throws at your machinery, using quality materials that are properly manufactured to handle those demanding conditions. The precision tolerances ensure proper oil clearance for reliable lubrication and long service life.

Installation Notes

Rod bearing replacement requires engine teardown, so make sure to check your crankshaft journals for wear and proper dimensions before assembly. Clean all oil passages thoroughly and torque the rod caps to factory specifications. If you’re doing a complete rebuild, this is the time to check your main bearings and other wear items too.
