Description
When you’re hearing that telltale blow-by coming from your tractor’s engine or noticing blue smoke on startup, worn piston rings are usually the culprit. This complete 4-cylinder piston ring set gets your engine sealed up tight again, restoring compression and stopping oil consumption that’s been eating into your operating costs.
What You’re Getting
- Complete set for all 4 pistons – no need to order multiple parts
- 12 compression rings at 1/8 inch thickness for proper sealing
- 4 oil control rings at 3/16 inch to manage lubrication
- Precisely sized for 3-3/8 inch standard bore engines
- TISCO quality construction built to handle farm work demands
Built for Real Farm Work
This ring set fits 4-cylinder engines with the common 3-3/8 inch bore found in many utility and mid-size agricultural tractors. These are the workhorses that handle everything from hay operations to loader work, where reliable power and fuel efficiency matter most. The standard bore specification means this fits engines that haven’t been rebuilt or bored oversize.
Made to Last
TISCO builds these rings to handle the constant heating and cooling cycles that farm engines face, along with the dust and debris that comes with agricultural work. The rings maintain proper tension and sealing properties through thousands of hours of operation, giving you the reliability you need during critical farming seasons.
Installation Notes
Ring installation requires proper tools and experience – this is typically a job for a skilled mechanic or engine shop. Make sure to check cylinder bore condition and piston clearances before installation. Gap the rings according to your engine manual specifications for best performance and longevity.
