Very helpful tool for mounting the piston in the cylinder. Who does not know the problem that the piston rings are under so much tension that the assembly in the cylinder develops into a patience game.
This tool is used to clamp the piston rings together in the piston. Then the piston is pushed through the tool from above into the cylinder until the piston is completely in the cylinder. Now push the piston just far enough out of the bottom of the cylinder until the piston pin can be installed. Done.
Fits pistons from 45mm to 125mm diameter.AI-translation
