Built for Real Farm Work
This bearing set fits the legendary Perkins AD3-152 engine found in popular tractors like the Massey Ferguson 135, 148, 152, 230, 240, and 250 series. These versatile tractors handle everything from cultivation and hay production to loader work and general farm maintenance. Whether you’re mowing pastures or pulling implements, this 45-horsepower workhorse needs proper bearing clearances to deliver full power.
Made to Last
TISCO bearings are manufactured to OEM specifications with the right materials and tolerances to handle diesel engine pressures and temperatures. The bearing material is designed to work with your engine’s oil system, providing proper lubrication flow while maintaining the precise clearances your crankshaft needs to run smoothly for thousands of hours.
Good to Know
Rod bearing replacement requires splitting the tractor and removing the oil pan, so it’s a good time to check your main bearings and plastigauge everything for proper clearances. Always check your crankshaft journals for scoring or out-of-round conditions before installing new bearings. If you’re not sure about the measurements, take it to a machine shop – it’s cheaper than doing the job twice.
