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.

Just tried it on a O320 and it worked great.

Good product. My engine was on a stand and we were removing all the pistons. Not sure how it would work removing one piston in an engine compartment with tight spaces.

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.

O-360 A1D narrow deck, used for removing piston pin from #3, very difficult with #1 cylinder installed. Plastic cap on end of bolt separated from the bolt on 1st attempt. Managed to get it started but it stopped due to the large hole on the band not lining up properly over the piston hole. Take it all apart and have to modify the band holes on wooden block end to allow band to move around some. Had to use a nylon dowel plus the tool to get in all the way out. It worked, but space is a concern and I had to improvise. Quality is OK. All the above is why I rated it average.

Poor quality, very sharp edges on strap. Razor sharp

it only lasts long enough to get about six pistons off, then the threaded rod goes through the rubber bushing on the end and then it’s ruined.

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.
