To dismantle this transaxle, a special wrench is needed to remove the finned differential retaining nut and not damage the aluminum fins. The dimensions were found and a drawing created. The parts were cut on the ProtoMax, except for the steel tubing, and consist of the starred wheel and the insert for a 3/8" ratchet.

A few welds to hold it together and a quick coat of paint finish it off.

This nut is not under a lot of compression, so the wrench doesn't have to be heavy duty. The starred part was cut from 1/8" steel plate and the insert for the ratchet cut from 1/4" steel plate. The tubing is 1.5" x 0.120 wall steel. It could have made it out of aluminum, but my welding skills are not that good yet!

Ingenious. I'll make sure we have this as an application we can discuss when we display ProtoMAX at SEMA (Specialty
Equipment show) and PRI, (Professional Racing show). Thanks!
