Hmm... (just woke up, hard to think).. let's see...
For assembly the list includes (but is not limited to):
- 10 mm wrench
- 14 mm wrench
- 8 mm wrench
- Philips (+) screwdriver
- Slot screwdriver
- Chain breaker
There are a number of other things that can be handy to have, I'm sure someone else will add to the list. For example, I like to have both a wrench and a socket/ratchet of each size at hand when working.
Before you install the motor do some reading around here on how to pull apart, inspect and prep it. There is often manufacturing waste in the ports (a dremel type tool and collection of bits help there) that can kill the motor early. There can be some junk down in the bottom of the case too if you go that far with it.
