Description
When your Case tractor starts showing signs of worn pistons—blue smoke, lost compression, or oil consumption you can’t ignore—it’s time for a complete rebuild. This kit gives you everything you need to restore your G188D engine’s heart back to factory specifications. Instead of hunting down pistons here, rings there, and sleeves somewhere else, you get the whole setup in one box.
What You’re Getting
- Complete 4-cylinder set with standard 3-13/16 inch bore pistons, sleeves, rings, pins, and retainers
- All components are precision-matched to work together for proper compression and seal
- Standard bore sizing means no machine work needed if your block is in good shape
- Everything’s included for a complete piston and sleeve refresh—no surprise trips to the parts counter
Built for Real Farm Work
The G188D was a workhorse engine that powered many Case tractors through long days of field work, loader duty, and everything else you throw at farm equipment. This engine was built for reliability, and this piston kit maintains that same standard. Whether you’re restoring an older machine or just need to bring back the power you remember, this kit gets you there.
Made to Last
Farm engines take a beating from dust, heat, and long hours under load. These pistons and sleeves are built to handle whatever your operation demands. The rings provide proper oil control and compression seal, while the matched tolerances ensure everything works together like it should for years to come.
Installation Notes
This is a complete overhaul job that requires engine disassembly and proper machining tools. Make sure your connecting rods are straight and within spec before assembly. A good tip from old-timers: check your cylinder bore taper before deciding on standard bore—sometimes a quick hone is all you need, other times the sleeves are your best bet for bringing everything back to spec.
