Description

When you’re hearing that telltale knocking sound from deep in your tractor’s engine or noticing oil pressure dropping off during heavy work, the main bearings are often the culprit. These bearings support the crankshaft and take tremendous abuse from the constant pounding of combustion forces and the twisting loads of field work. This standard-size main bearing kit gives you everything needed to restore proper crankshaft support and get your International Harvester tractor back to reliable operation.

What You’re Getting

Complete bearing set manufactured by TISCO to OEM specifications for reliable fit and performance
Standard size bearings that restore proper clearances on unworn crankshafts
Precision-engineered bearing shells that handle the demanding loads of agricultural work
Quality materials and construction that stand up to the constant stress of heavy-duty operation

Built for Real Farm Work

This bearing kit fits a range of International Harvester tractors where reliable power is essential for getting the job done. Whether you’re running a utility tractor for daily chores or a row-crop machine during planting and harvest, these bearings provide the foundation for dependable engine operation under the demanding conditions that come with farm work.

Made to Last

Farm engines work harder and longer than most, dealing with dust, dirt, temperature extremes, and heavy loads that can quickly destroy inferior bearings. TISCO manufactures these bearings to handle the punishment of agricultural use, with proper metallurgy and precision tolerances that ensure long service life when properly installed and maintained.

Installation Notes

Main bearing replacement requires complete engine disassembly, so it’s a job for experienced mechanics or professional shops. Always check crankshaft journals for wear, scoring, or out-of-round conditions before installation. If the crank needs machining, you’ll need undersized bearings instead of these standard ones. Proper torque specifications and assembly procedures are critical for bearing life and engine reliability.
