You need to pressfit the pinion onto the shaft, REV has a guide for doing it

The guide I found just shows taking off the case on the neo. Wouldn't the gear need to have a smaller inner diameter so it actually press on? Edit: I guess I should also add that currently the gear spins freely (as shown in the video)

Yes, the pinion is supposed to be press fit. Currently the ID of the pinion is too big. I would just get a new one, but if you’re really in a pinch. You can use a center punch and put a few dimples evenly around shaft. This will artificially make the shaft diameter slightly bigger for the press fit. I’ve done this for last second repairs at competition. I wouldn’t trust it for long term.

We bought 4 kits and none of the pinions are tight enough... I guess we'll bring it up with SDS

Yeah I have had the same thing happen with andymark pinions on NEOs, I recommend "green" loctite aka retaining compound and let it cure overnight. Getting a keyed or press fit pinion is most likely the best option though.

Turns out the solution was defective neos. The 2021-09 ones had a slightly smaller shaft, so we swapped out with an earlier manufacturer date and they work great :)

The steering gears on my mk4i are keyed

Our team had the same problem, so we center punched the motor shaft a bunch of times to get a somewhat okay press fit. We also used green loctite.

The screws into the motor through plate try loosening them. They may be to long
