Made to Last
TISCO doesn’t cut corners on engine internals because they know what’s at stake. These main bearings are manufactured to handle the heavy loads and constant stress of agricultural engines that often run at full throttle for hours at a time. The proper metallurgy and coating ensure they’ll provide reliable service through thousands more hours of operation.
Good to Know
Main bearing replacement is engine-out work that requires proper tools and experience. While you’ve got the engine apart, it’s smart to check rod bearings, crankshaft journals, and oil pump clearances. Make sure everything’s clean during assembly and use proper torque specifications—this is one job where shortcuts lead to expensive problems.
