I can't seem to find the pitch angle of the FP pinion gear. I don't have pitch gear tool. It seems like an odd size, can anybody help?

32 Diametral Pitch, 20 degree pressure angle. I am 100% positive of these numbers.

Thanks Paul,
Do you know where I can order the actual driven 72 tooth gear. I can't track it down as Mabuchi makes motors and I can't locate the manufacturer of the gears. I use them in robot class and need to bulk order them. I use Mabuchis and these gears to create drive trains. We scale down to a 1/3 the FRC contest from previous year. To buy these gears as steel or acetal is expensive.

The only way I know to get the driven gear is to go to a powerwheels distributor and order the whole gearbox. It is not that expensive. I know the gear only costs a few cents, but I do not know how to just get that gear.

I think a TON of teams only use the F-P motor, that leaves a lot of excess F-P transmissions. I would put out a plea for teams to drop their extras in the mail to you.

It is worth a shot.

Bah... Buying the gear from MSC (http://www1.mscdirect.com/CGI/NNSRIT?PMPXNO=5506751&PMT4NO=5056094) is less expensive than buying the whole gearbox.

Also, if you are going to buy many, you may want to go to Stock Gears, Inc. (http://www.stockgearsinc.com/default_wn.htm), who is the original manufacturer.

Good luck,
Andy

I have contacted the Mattell people who oversee FP and they can get single gear. Will post when I get final answer
