Description

When your WD45 starts smoking more than it should, burning oil, or just doesn’t have the power it used to, it’s time for an engine rebuild. After decades of hard work, those cylinder sleeves and pistons have done their job—now they need replacing to get your tractor back to pulling strong and running clean. This complete overhaul kit gives you everything you need to bring that 226 cubic inch gas engine back to life.

What You’re Getting

Complete cylinder sleeves, pistons, rings, and pins for a fresh start on all four cylinders
Full overhaul gasket set to seal everything up tight from top to bottom
4-inch standard bore with 4-1/8-inch overbore option so you can match your engine’s current condition
Tru-Power quality components built to handle the demands of farm work

Built for Real Farm Work

The WD45 was Allis Chalmers’ workhorse tractor from the mid-1950s through the early 1960s, and plenty are still earning their keep today. Whether you’re using yours for cultivation, hay work, or running a PTO-driven implement, this 226 CID engine was built to work hard. This kit restores that original power and reliability so you can keep working the ground like these tractors were meant to do.

Made to Last

Engine rebuilds aren’t something you want to do twice, so this kit uses quality materials that’ll hold up to the heat, pressure, and vibration inside your engine. The sleeves are properly sized for a good fit, and the piston rings are designed to seal properly from day one while lasting through many seasons of work.

Good to Know

This is a basic overhaul kit, so you’ll need to order engine bearings separately to complete your rebuild. Most shops recommend checking your crankshaft and having it turned if needed while you’re this deep into the engine. If you’re not sure about your bore size, measure before ordering—this kit comes with the overbore sleeves to handle most situations.
