Description
When your big diesel starts blowing blue smoke, burning oil faster than you can add it, or just doesn’t pull like it used to, it’s telling you the cylinder sleeves and pistons are worn out. Farm engines work harder and longer than most people realize, handling constant heat cycling and combustion pressures of diesel operation. This complete sleeve and piston kit gives you everything you need to breathe new life into that 404 cubic inch six-cylinder powerhouse.
What You’re Getting
- Complete set of cylinder sleeves, sleeve seals, pistons, rings, pins, and retainers for all six cylinders
- Precision-engineered components designed to handle thermal cycling and high pressures of diesel operation without blowing out or losing compression
- Quality materials that restore proper compression and oil control to get your engine running strong again
- Everything included in one kit – no need to hunt down individual components or worry about compatibility
Built for the Long Haul
This kit fits the 404 cubic inch diesel engines found in larger tractors and heavy equipment where reliability matters most. These six-cylinder powerplants are the workhorses that pull wide tillage equipment, run big balers, and power through the toughest field conditions day after day.
Made to Last
The sleeves are cast iron, pistons are three-ring design, and all components use modern materials that meet or exceed original specifications. The design accounts for thermal expansion and the demands of extended operation under load – whether you’re running all day in heavy ground or powering demanding PTO applications.
Installation Notes
This is a complete in-frame rebuild kit that requires engine teardown with the block staying in the tractor. Take your time with measurements and clearances – checking cylinder bore condition and measuring everything properly before assembly saves headaches later. If your crankshaft bearings are questionable, now’s the time to replace them too.
