The hobby shop should have some but you don't have to remove it just unscrew it like normal. You don't have to remove it.
I use it on all my pinions. Just as a preventative.
A new set screw would possibly work as well. Or pinion entirely.
I use the team associated locking adhesive,
Part # 1596.
A tiny drop will do ya.
