Re: paper: Easy to convert Screw-driver Gear-boxes
I have added a couple of internal shots of the Milwaukee we are using with the FRC2012 legal motor and leads shown (thanks Jim).

We decided to use this unit in place of our original drive system which was a DEWALT XRP with a 775. Note that 775 is a very easy replacement/isntallation into the XRP as it has the same shaft as the original DEWALT motor.

The Milwaukee with 550 is considerably lighter than the XRP 775 combo. If memory serves me correct, the XRP/775 was right at 3 lbs where as the Milwaukee/550 was right around 1.5 lbs. This was discovered due to a weight crunch issue right before "Bag Day".

Here is a link to the "bare" version of the Bosch unit on amazon

This is a great little unit that is relatively cheap. For 50$ you have a lightweight 2-speed gearbox with internal anti-backdrive pins.

For all of these conversions, you will need a pinion puller like this one:
