Description
When you’re staring at blue smoke coming from the exhaust stack or noticing oil consumption that’s got you checking the dipstick more often than you’d like, worn piston rings are usually the culprit. This complete ring set gets your John Deere’s 179 cubic inch three-cylinder diesel engine back to sealing properly, restoring compression and stopping that oil burn.
What You’re Getting
- Complete ring set for one cylinder with three precision-fitted rings per piston
- Keystone design top ring (1/8″ thick) that handles combustion pressure and heat
- Two oil control rings (3/32″ and 9/64″) that keep oil where it belongs
- 4.19″ bore size engineered for proper cylinder wall seal and long life
- OEM quality materials that match original equipment specifications
Built for Real Farm Work
These rings fit the 179 CID three-cylinder diesel engines found in various John Deere tractors, both naturally aspirated and turbocharged versions with serial numbers 350,000 and up. Whether you’re running a compact utility tractor for farmstead work or powering through field operations, this engine has been a workhorse in the John Deere lineup for years.
Made to Last
Piston rings live in one of the harshest environments in your tractor – constant heat, pressure, and friction while sealing combustion gases and managing oil flow. These rings are manufactured to handle the thermal cycling and wear that comes with long days in the field, maintaining proper tension and seal integrity season after season.
Good to Know
Ring installation requires pulling the pistons, so this is typically part of a larger engine rebuild or overhaul project. Make sure your cylinder walls are within spec and properly honed before installing new rings. Take your time with ring gap measurements and use proper ring compressors during assembly – rushing this job leads to broken rings and a do-over.
