Description
When your trusty WD45 starts burning oil, losing compression, or just doesn’t have the power it used to, it’s time for a complete engine rebuild. This comprehensive overhaul kit gives you everything needed to bring that 226 cubic inch four-cylinder back to life. Instead of hunting down parts piece by piece or wondering if you’re getting the right specifications, this kit takes the guesswork out of your rebuild project.
What You’re Getting
- Complete sleeve and piston assemblies machined to proper 4-1/8 inch overbore specifications
- Full gasket set including head gasket, oil pan, and all sealing components for a leak-free rebuild
- Main bearings and rod bearings engineered for the loads these work tractors handle
- Cam bearings and valve parts to restore proper timing and compression
- Everything precision-matched to work together for reliable performance
Built for Real Farm Work
The WD45 was Allis Chalmers’ workhorse tractor from the 1950s, built for row crop farming, hay work, and loader duty. These orange machines earned their reputation pulling plows, running PTO-driven equipment, and handling whatever job needed doing around the farm. This overhaul kit restores the power and reliability that made these tractors legendary.
Made to Last
Tru-Power builds this kit with components designed to handle the demands of agricultural work. The pistons and sleeves are engineered for the cylinder pressures and heat cycles of hard-working farm engines, while the bearings use materials that stand up to dust, moisture, and heavy loads that come with decades of field use.
Good to Know
This is a complete rebuild kit, so plan on a full engine teardown and machine work. The 4-1/8 inch overbore gives you plenty of cleanup for worn cylinders while maintaining proper wall thickness. Make sure to have your block and head checked by a machine shop for cracks and warpage before assembly. A good rebuild done right will give you many more years of reliable service.
