Description
When your Allis Chalmers starts burning more oil than diesel or you’re hearing that telltale knock coming from under the hood, it’s time to face facts—your engine needs attention. This comprehensive overhaul kit gives you everything you need to breathe new life into that trusty 4-cylinder gas engine without pulling it out of the frame, which means less downtime and more time getting back to the work that needs doing.
What You’re Getting
- Complete sleeve, piston, and ring set engineered for 4-inch standard bore or 4-1/8 inch overbore applications
- Wrist pins and clips that handle the stress of hard-working farm engines
- Full valve-grind gasket set to seal everything up tight from head to oil pan
- Oil pan gasket included so you won’t be hunting for parts halfway through the job
- Tru-Power quality that’s built to handle the demands of real farm work
Built for Real Farm Work
This kit fits the backbone of Allis Chalmers farming—the W, W25, WC, WD, and WF series tractors that have been earning their keep on farms for decades. These 201 cubic inch powerplants were designed when tractors were built to last, and many are still pulling plows, running balers, and powering PTO equipment today. Whether you’re running a row-crop WC through corn season or using a utility WD for loader work, this engine has proven itself in every kind of farm application.
Made to Last
Tru-Power has been building engine components for farm equipment long enough to understand what works in real-world conditions. The pistons and rings are designed to handle the heat cycles and loads that come with field work, while the gasket set uses materials that stay flexible through temperature swings and won’t leak when you’re counting on them most.
Good to Know
This is an in-frame kit, which means you can rebuild your engine without the headache of pulling it completely out—a real time-saver when you’ve got crops waiting. You’ll need to order main and rod bearings separately, so plan ahead when placing your order. Having all your gaskets and seals on hand before you start will keep the project moving smoothly.
