Engine Proper Unit disassembly tools by GOANDY

Text by GOANDY:

The proper (rotor) unit is removed from the gearbox assembly without taking everything out of the frame.

Follow the book for the steps. If you don't have the book (s) then buy them!

The rotor oil seals can only be inspected and the rubber parts replaced by tearing down the proper unit.

Rubber/nitrile o rings can be purchased. Search for my proper unit rebuild thread for the details.

The metal oil scraper rings which sit either side of the rotor are not available but can be carefully ground down to get the correct profile back. I did it using an electric motor with a backing plate to mount the oil rings on then held them at the correct angle against some wet emery paper.

To do all this you need a stack of tools and also you'll need the special tools for putting it all back together. There's a template

Thanks Wayne. That template is from ?Tonny up in Denmark I think- he used to maintain the RE5 registry. My buddy Steve had the tools laser cut and we built a few proper units using them. They worked well (as they should). It would be very difficult to do a rebuild without them.
