I know you were the first one to bring up these concerns and I agree with you completely, I was just adding another voice to the argument.

In our gearbox we had a 1:1.4 spur gear (20 to 28 tooth) reduction from each of the cim motors before the 1:10 reduction of the worm gear (4 start worm and 40 tooth gear). The worm gear was on the output shaft. It can be seen here http://www.chiefdelphi.com/forums/sh...ht=192+gearbox.
