5 Stars Perfect Replacement!


Eugene in Michigan from MI wrote (July 23, 2014):

This was a perfect replacement for the worn-out coupler on the pump of my PTO log splitter. You might need a bit of fine emery paper to remove the paint on the inside of the shaft bore and/or a small file to debur/widen the keyway, but otherwise it was a easy install. My old coupler used a thumb screw to secure it to the PTO shaft, so the spring-loaded lock on this one will make life easier. This appears to be a well-made item that will give me years of good service.
