Wondering if anyone has one of the special Trico and believe Snap-On also made them tool bit for removing the oval screws in the Trico Wiper Motors. Sure would like to obtain one if you have one laying around.

There is a fellow Denny Graham who posted a photo showing how to make something similar to what is shown in the for sale ad. No idea if it works but looking at the size of a Trico screw, drilling the #18 hole in a piece of 1/4 or 5/16 rod and flattening the sides looks like it might actually work.

With a long enough rod you could buy a file handle and drill the end out to glue or pin the rod into the handle to make a driver tool.

The assembly is non-ferrous and I have taken a number apart and always with needle nose pliers. There may be a small amount of white aluminum oxide present but it has never caused any seizing of the fasteners in their threaded holes. You do not want to over tighten anything anyway as the cast parts are on the fragile side.
Brake fluid is my lubricant of choice along with careful removal of the gaskets to use as a pattern so new ones can be cut from the same thickness of gasket paper which is available at most part stores.
