If you've got a Husqvarna or Partner cutoff saw that's lost its compression, this kit is for you.

It's a brand new 51mm cylinder and piston kit, specifically designed to fit models like the Husqvarna K750 and K760, and the Partner versions of the same saws.

The model number is 506386171.

The cylinder diameter is 51mm, and the hole-to-hole length on the piston is 46mm.
It's made to work with saws that take a max 14-inch blade and run on gasoline.

The color is a standard gray, and everything you see in the picture is included in the pack.
The compatible brand is Husqvarna, and the displacement is 73.5cc.
It's manufactured in 2024 in China and comes with a 6-month warranty.
