Description
When your diesel’s burning oil, blowing blue smoke, or just doesn’t have the power it used to, worn pistons and rings are usually telling the tale. Compression loss and oil consumption problems rob your engine of power and efficiency, but this complete oversize kit gets things back to where they should be. It’s got everything you need for a proper rebuild—pistons, rings, pins, and retainers all in one package.
What You’re Getting
- Complete set of 1.0mm oversize pistons designed for proper bore clearance after machine work
- Matching piston rings that seal tight and control oil consumption like they should
- Wrist pins and retainers included—no hunting around for missing pieces
- All components precision-matched for the 6TA-590 turbocharged engine
- Everything needed for one complete 6-cylinder engine rebuild
Built for Heavy-Duty Work
The 6TA-590 is a workhorse 6-cylinder turbocharged and aftercooled diesel that powers some serious farm equipment. These engines are built for tractors that handle heavy pulling jobs—deep tillage, manure spreading, and running big implements where you need reliable power transfer. Whether you’re running cultivation equipment or pulling heavy loads, this engine needs to deliver consistent power under demanding conditions.
Made to Last
Quality construction handles the harsh conditions inside diesel engines—high compression ratios, constant heat cycling, and the contaminants that come with farm work. These components are built to maintain proper sealing and performance through thousands of operating hours, just like the original equipment.
Installation Notes
This is a 1.0mm oversize kit, so you’ll need to have your cylinders bored and honed to match. It’s a rebore kit, which means proper machine shop work is essential for success. When you’re doing the work, take time to check your cylinder head for cracks and have it pressure tested—no sense putting new pistons in an engine with a bad head.
