Description
If your old Allis Chalmers is burning oil, blowing blue smoke, or just doesn’t have the power it used to, chances are it’s time for new pistons and sleeves. When these vintage tractors start showing their age with compression loss and oil consumption, this complete rebuild kit gets your engine back to running like it should. There’s nothing quite like hearing that B or C fire up and purr after a good rebuild.
What You’re Getting
- Complete set of flat-head sleeves and pistons designed specifically for 4-cylinder gas engines
- 3-7/16 inch overbore size gives you fresh cylinder walls and restores proper compression
- Includes pistons, pins, retainers, plus both chrome top rings and oil control ring sets
- TISCO quality parts that meet original specifications for reliable performance
Built for Real Farm Work
This kit is designed for the classic Allis Chalmers tractors that built the brand’s reputation—the B, 1B, C, CA, B15, and B125 models. These were the workhorses that handled everything from cultivating to belt work around the farm. Whether your tractor’s been pulling a two-bottom plow or running the buzz saw, this rebuild kit brings back the power these machines were known for.
Made to Last
TISCO builds these parts to handle the demands of farm work, just like the original factory components. The flat-head design matches what Allis Chalmers used, and the overbore specification means you’re getting maximum life out of your rebuilt engine. The chrome rings resist wear and provide excellent sealing for consistent compression.
Installation Notes
This is an overbore kit, so your cylinders will need to be bored and honed to 3-7/16 inch before installation. Most any machine shop can handle this work. Make sure to have your connecting rods checked and resized while the engine’s apart—it’s cheap insurance for a long-lasting rebuild.
