Description
When your 6TA-590 Perkins is blowing blue smoke, down on power, or you’re hearing that telltale piston slap during cold starts, it’s time for a proper rebuild. This oversized piston and ring kit gets your turbocharged diesel back to running like it should—strong compression, clean burn, and the power to pull whatever you hook behind it. Whether you’ve worn the cylinders past standard bore or you’re doing a full rebuild, this 0.5mm oversized kit has everything you need in one box.
What You’re Getting
- Complete set of pistons, rings, pins, and retainers for all six cylinders—no hunting for individual pieces
- Oversized 0.5mm pistons designed specifically for Perkins 6TA-590 turbocharged applications
- Quality ring sets engineered to handle the heat and pressure of turbo operation
- Wrist pins and retainers included so you don’t get stuck waiting for small parts
Built for Turbo Power
The 6TA-590 was Perkins’ workhorse engine for mid-range tractors and industrial equipment that needed serious pulling power. These engines powered dependable Massey Ferguson tractors used in grain operations and heavy farming, where turbocharging made the difference between getting the job done and getting stuck. This kit restores that factory compression ratio your turbo depends on for proper boost pressure and fuel efficiency.
Made to Last
The piston and ring materials are designed to handle the thermal cycling and high pressures of diesel operation. Turbocharged engines run hotter and work harder than naturally aspirated motors, so these components are built to take the abuse. Quality casting and proper ring tension mean you’ll get thousands of hours before thinking about another rebuild.
Good to Know
This is an oversized kit, so you’ll need to have your cylinders bored and honed to 0.5mm over before installation. Check your cylinder bore taper and out-of-round measurements before ordering—if you’re beyond 0.5mm oversized already, you’ll need sleeve work or a different size kit. Take your time with ring gap measurements and follow proper break-in procedures for best results.
