Overview

This tool takes all the work and risk out of removing the piston pin. It works on most Lycoming and Continental engines. Just slip it over the piston, turn the shaft and it pushes the pin out smoothly and cleanly. Vinyl coated tip prevents scratching and marring the pin or piston during removal. Will handle up to 5.5" pistons.

This tool worked as well as expected in removing piston pins from an O-320. The big advantage is there is no side load put on the connecting rod.

Good tool, like many good tools, required a slight modification to make it better. Used to remove E-225 5 Piston from right rear cylinder while still on aircraft. Tool wouldnt quite fit as delivered, as it was up against the adjacent cylinder barrel. Drilled additional holes further down the band and was able to get it into position and had the pin out within minutes.

It will not work on all situations. If you have a cylinder that is blocked by an adjacent cylinder such as an IO360 there is no way you can get it position even with some type of alteration. There is only one way the pin is going out and there is not enough angle to get it in even if you removed the adjacent push tubes. Sending it back.
