Description
When your Allis starts burning oil, losing power, or making those sounds that tell you the engine’s seen better days, it’s time for more than just a tune-up. This complete overhaul kit gives you everything you need to bring that tired engine back to life, with the convenience of having all the parts in one box instead of hunting down pieces from a dozen different suppliers.
What You’re Getting
- Complete sleeve and piston kit sized for 4-1/8 inch overbore to restore proper compression
- Full gasket set that seals everything from head to oil pan
- Standard rod and main bearings plus cam bearings for a complete bottom-end rebuild
- New intake and exhaust valves, springs, guides, and valve keys for proper breathing
- Tru-Power quality components designed to meet or exceed original factory specifications
Built for Real Farm Work
This kit is designed for Allis Chalmers tractors that need the larger 4-1/8 inch overbore to restore proper cylinder walls and compression. Whether you’re running an older row-crop tractor for cultivation work or a utility model for hay operations, this overhaul brings back the power and efficiency you remember from when that tractor was new.
Made to Last
Tru-Power has been making engine rebuild components for decades, and they understand what farm tractors demand. These aren’t bargain parts that’ll leave you doing the job twice. The pistons, rings, and bearings are built to handle the heat cycles and continuous operation that come with real farm work.
Good to Know
This is a complete overhaul kit, so you’ll be pulling the engine or doing major teardown work. Having everything in one kit eliminates the frustration of getting halfway through the job and realizing you’re missing a gasket or bearing. Most farmers tackle this project during the off-season when the tractor can be down for a few weeks.
