Torque Amplifier: 460 vs 300u.....Extra Gear??

[LD1]

Working on my 300 utility project. Got a torque amplifier for a killer deal. Out fo a 460. Mine was totally junked.

Only one slight difference, the 460 has an extra gear on the output. It doesnt look like it will interfere with anything, and the rest of the dimensions are the same, but I gotta ask what the gear is, and if it is going to be a problem. Cause if it is, I can always take it appart (which I dont want to do) and put my output shaft in.

Here are some pics, the extra gear has a red arrow pointing to it

I hope these links come through... I checked a 460 T/A, and it looks like the same for your 300, although I didn't check the part #'s. So for giggles, I checked the one for a 560, and it has the extra gear.
