When your engine starts knocking or you're losing oil pressure, those main bearings are telling you they've reached the end of the road. There's no working around worn main bearings - they keep your crankshaft centered and spinning smoothly, and when they go bad, your whole engine's in trouble. These standard-size main end bearings get your tractor's heart beating strong again. What You're Getting Standard-size bearings that restore proper crankshaft clearances without machine work Precision-manufactured to handle the loads these three-cylinder engines put out Quality materials that resist the heat and pressure of hard farm work Complete set gives you everything needed for both main bearing positions Built for Real Farm Work These bearings fit the reliable Perkins A3.152 and AD3.152 engines that power classic Massey Ferguson tractors like the 35, 135, 240, 250, 340, 350, 352, and 550. These three-cylinder workhorses have been the backbone of small to medium farms for decades, handling everything from cultivation to hay production to loader work. Made to Last Engine bearings take a beating - they're constantly under pressure, dealing with combustion forces and the weight of that spinning crankshaft. These bearings are manufactured to precise tolerances and use materials designed to handle the demanding conditions inside your engine. When properly installed with clean oil and correct clearances, they'll give you thousands more hours of reliable service. Good to Know Installing main bearings means splitting the tractor, so this is typically a job for winter when you've got time for a complete engine rebuild. Always check bearing clearances with Plastigauge and make sure your crankshaft journals are in good shape before installation. Clean assembly is critical - any dirt or debris will destroy new bearings quickly.

Nothing kills a good day in the field faster than rod knock starting up from your tractor's engine bay. When your trusty TEF20 starts knocking or showing signs of worn rod bearings, you don't want to be sidelined during busy season. These oversize connecting rod bearings get your Little Grey Fergie back to work by giving you that extra twenty thousandths of material to compensate for a crankshaft that's been machined to restore proper oil clearances. This complete bearing set includes everything needed to rebuild your Perkins 3.152 engine's bottom end properly, so you can get back to work without worrying about expensive engine failure. What You're Getting Complete set includes big end bearings, main bearings, and thrust washers for a full 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. Standard size bearings designed for engines with crankshafts still within OEM specifications Quality materials and construction ensure long service life under demanding farm conditions Complete thrust washer set maintains proper crankshaft end play and prevents damaging movement Built for Hard-Working Farm Engines This bearing set fits a wide range of tractors powered by the legendary Perkins 3.152 engine family, from the classic Ferguson TEF20 "Little Grey Fergie" to the popular Massey Ferguson 35, 135, and 148 models. The Ferguson TEF20, often called the "Little Grey Fergie," revolutionized farming in the 1940s and 50s with Harry Ferguson's three-point hitch system. These 20-horsepower workhorses handled everything from plowing small fields to powering sawmills and hay balers. The Massey Ferguson 35, nicknamed "Gold Belly" for its distinctive gold-painted engine, became one of the most popular tractors ever built. Today, these vintage machines are still working hard on small farms, market gardens, and hobby farms. Made to Last 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. The bearing materials are specially formulated to withstand the constant pressure changes and temperature cycles that come with agricultural work, from early morning cold starts to long days under load pulling implements through tough conditions. Installation Notes 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. A good tip is to keep the old bearings for reference when talking to your machine shop about the grinding work needed. While you're doing the rebuild, it's also smart to check the oil pump and replace the oil pan gaskets since everything is accessible.
