Description

When you’re losing compression and burning oil like it’s going out of style, worn piston rings are usually the culprit. You know the signs: that telltale blue smoke on startup, oil consumption that keeps you buying cases of the stuff, and cylinder compression that’s just not what it used to be. This complete piston ring set gets your engine sealing tight again and puts the power back where it belongs.

What You’re Getting

Complete set includes 1/8-inch keystone compression ring, 3/32-inch second compression ring, and 0.197-inch oil control ring
Keystone design on the top ring provides superior sealing and prevents ring sticking in the groove
Precision-machined for 4.02-inch bore to restore proper compression and oil control
One complete set services one cylinder in your 329 cubic inch diesel engine
Built to handle the heat and pressure cycles of diesel combustion

Built for Real Farm Work

This ring set is engineered for the 329 cubic inch 6-cylinder diesel engines found in various tractor models, particularly those with serial numbers 277550 and up. These engines were workhorses in their day, powering through field work, loader operations, and power take-off duties. The 329 CID displacement provided good torque for its size class, making it popular in mid-range tractors.

Made to Last

Diesel engines run hot and work hard, so these rings are built accordingly. The keystone design on the top compression ring prevents carbon buildup from locking the ring in place – a common problem with conventional rectangular rings in diesel applications. Each ring is manufactured to exact specifications to restore proper cylinder sealing and oil control.

Installation Notes

Ring installation requires careful attention to orientation and gap clearance. The keystone ring goes in the top groove, and each ring has specific installation requirements. Check your manual for proper end gap specifications and ring orientation. Take your time during assembly – proper ring installation is critical for engine longevity and performance.
