Andymark Planetary Transmission...

we're using what I assume are the andymark planetarys (the '07 KOP ones)

The 2007 KOP gearbox was a Banebots 56mm gearbox (since discontinued and replaced by the P80)

Could anyone tell me how to mount a FP motor to the this kind of gearbox? I'm not sure if we're allowed to yank the gear off, and if so, how?

Personally I'd buy the Planet with the motor already attached:

Then I'd buy this to make swaps easier:

Which gearbox are you refereing to? If you are talking about the AM Planetary Gearbox (http://www.andymark.biz/am-0002.html),then yes you have to remove the existing gear and press the new gear that comes with the planetary on to the shaft of the motor. Unless you buy the ones that are pretty much ready to go like RC pointed out.

We always use an Arbor Press to do this, but you must be very careful no to bend the shaft of the motor. For more info try these threads:

Yeah, that's the one, but to my knowledge it did not come with a new gear.
:S As we are a rookie team we weren't aware of this.
I do not believe our school has an arbor press either.

Is it a viable option to drill out the mounting pate to a diameter that would accept the gear?

The problem is not to make the gear fit through the hole, the planetary is designed to work with the 15 tooth 32 pitch pinion and it will not work with anything else (others would not mesh properly with the planet gears).It should have come with the Planetaries, if it didn't I would try to contact AndyMark and ask them about it. The website lists it as part of the hardware.

Hardware
# Two 8mm id ball bearings, (19mm od, 22mm od) supporting output shaft
# steel planet and sun gears, 32 dp, 20 degree p.a.
# Five planet gears (12 tooth)
# 15 tooth sun gear, with 0.125 inch bore
# 40 tooth ring gear
# Two #10-32 mounting holes, on a 1 inch radius from center

If you do not have an Arbor Press, your best bet is to order the mounting plates w/ motor that are ready to be installed. Our team has gotten away with using a vice to press the gear onto the shaft at the events but I do not recommend it.

[Damaku250]

Would it be in any way acceptable to bore the planetary mounting cap larger?
We believe this would be the easiest way as it would allow for easy motor replacement in the event of failure, and would be the most economical.

bane bots trans. have cost us too many matches for me to EVER trust them again...

ANDY MARK is the way to go....

AM parts are all high quality, easy to use, and the stand behind their product 100%

wish I could say that about bane bots...... I cant....

I would not recommend making any holes in the gearbox or motor mounting plate. This will allow debris to enter the gearbox and do bad things to it.

[Damaku250]

According to one of our mentors/post-secondary students, there was a shipping error resulting in some teams actually ending up with a 15-tooth pinion on the FP motor, which I think might be the case as it seems to mesh properly with the AM planetary. the normal stock 19-tooth wouldn't do that would it?
If this is the case, would that mean we just need to yank the gear off (with a neighbouring team's arbor press), install the back plate then re-install it?

The Planetary comes with the proper gear to install on the FP output shaft. Just to be safe, I would always use that.

As stated above, we appear not to have received said gear.

We're using the planetaries in a funky way, 2 FP's, going into 2 planetaries going into a toughbox. This will operate our kicker.

wow, got enough torque there dude?
