Description
When your Oliver or White tractor starts burning oil, losing compression, or just not pulling like it used to, worn piston rings are usually the culprit. You’ll know the signs – blue smoke from the exhaust, oil disappearing between changes, and that sluggish feeling when you’re pulling implements. This ring set gets your engine back to sealing properly so you can get back to the field work that’s waiting.
What You’re Getting
- Complete ring set with three compression rings at 3/32 inch and one oil control ring at 1/4 inch
- Precision fit for 3-3/4 inch bore cylinders – no guesswork on sizing
- One complete kit services one cylinder, so order according to your engine configuration
- Quality TISCO construction built to handle the heat and pressure cycles of diesel operation
Built for Real Farm Work
This ring set fits Oliver and White tractors with the 3-3/4 inch bore engines that powered many of the utility and row-crop machines from that era. Whether you’re running a smaller utility tractor on hay equipment or working ground with a larger row-crop model, these are the workhorses that spent decades doing everything from cultivating to loader work.
Made to Last
TISCO builds their piston rings to handle the harsh conditions inside diesel engines – high compression ratios, constant heat cycling, and the contaminants that come with farm work. These rings are manufactured to maintain proper tension and sealing through thousands of operating hours.
Installation Notes
Ring installation requires engine disassembly and proper measuring tools to ensure correct fit. Check your cylinder bore for wear or scoring before installing new rings – sometimes cylinders need honing for proper ring seating. Take your time with ring installation and follow proper ring gap procedures for best results.
