Description

When your MF 135’s A.152 engine starts knocking or showing signs of worn main and rod bearings, it’s time to get serious about a rebuild. Engine bearings take tremendous loads, especially in agricultural applications where engines run for hours at varying RPMs. These oversized bearings are manufactured to handle the stresses of farm work while providing the proper oil film thickness for reliable lubrication and heat dissipation. This complete bearing set gives you everything needed to get your engine back to reliable service.

What You’re Getting

Complete main and connecting rod bearing set sized 20 thousandths oversize for proper crankshaft fitment
Quality construction designed to handle the constant loads and vibration of farm work
Proper bearing materials that provide excellent oil retention and heat dissipation
Manufactured to handle the stresses of farm work while providing the proper oil film thickness for reliable lubrication

Built for Real Farm Work

The MF 135, powered by reliable Perkins AD3.152 3-cylinder diesel or Continental gasoline engines delivering 45.5 horsepower, became one of the most popular tractors of its era with several hundred thousand units produced worldwide. These versatile utility tractors excel in diverse farming applications including cultivation, planting, mowing, hay production, livestock management, and general farm utility work. Your A.152 engine is the heart that keeps all that work happening.

Made to Last

Farm engines don’t get easy lives – they run long hours at varying loads, deal with dust and dirt, and need to keep going when there’s work to be done. These bearings are built with the same quality standards as original equipment, using materials that can handle the punishment while maintaining proper oil clearances for thousands of hours of service.

Good to Know

Installing oversize bearings requires having your crankshaft machined by a qualified machine shop to the proper dimensions. Always check crankshaft journal diameter with a micrometer before ordering, and consider replacing the main bearings at the same time if you’re doing a complete bottom-end rebuild. This is precision work that’s worth doing right the first time.
