Could really use some motor help - made mistakes :(

I could really use some help here... I realize I made a few mistakes.

1. I got a 2.8:1 gearbox for my Graupner Speed 600 motor. The instructions say that the distance from the front motor casing to the top of the pinion needs to be 12mm. This means cutting the shaft. Any advice on how/what to cut that shaft with?

2. The pinion I received with the gearbox was a 'press fit' pinion. I tried installing in on the shaft with a small rubber hammer. Long story short.. after a lot of 'tapping' I ended up pushing the back of the motor out of the casing. I managed to re-assemble the motor but I worry that I have somehow damaged it now. Any thoughts on this?

3. HOW does one get a pinion on to the shaft? Is there a special tool to buy?

Thanks for the help!
