Description

Nothing ruins your day like engine knock or mysterious oil pressure drops that signal bearing trouble. When the crankshaft in your John Deere diesel gets a little out of spec from years of hard work, you don’t always need a complete rebuild. This .020″ undersized main bearing kit gets you back to proper clearances and oil pressure without breaking the bank on a full overhaul.

What You’re Getting

Complete set with one center bearing and four main bearings to rebuild your crankshaft properly
Precision .020″ undersize that matches standard machine shop practices for crankshaft turning
Quality construction that handles the demanding loads and heat cycles of diesel operation
Direct replacement kit that eliminates guesswork when ordering individual bearings
Proper oil clearances restored for reliable lubrication and pressure

Built for Hard-Working Diesels

This bearing kit works in John Deere’s proven 202, 219, 239, and 276 cubic inch 4-cylinder diesel engines that powered countless tractors through decades of farm work. Whether your machine’s been running a grain drill, pulling implements, or handling loader work, these engines were built to last and this kit helps you keep them running strong.

Made to Last

Main bearings take more punishment than almost any other engine component, supporting the crankshaft through thousands of power strokes while dealing with combustion pressure and heat. These bearings are manufactured to handle those demanding conditions with proper materials and precise tolerances that restore your engine’s original performance.

Good to Know

This is a job for someone comfortable with engine work or a qualified mechanic. Your crankshaft will need to be turned .020″ undersize by a machine shop before installing these bearings. Check your crank journals carefully for scoring or out-of-round conditions before committing to this repair. When done right, you’ll have an engine that runs like new for years to come.
