Has anyone seen this part sold individually?

Last week I drove over to Red's Hydraulics and bought some switch overs to put over the switches on a model im going to make as well as a model I already have built. I made some adjustments to the switch covers so they can fit the switches better. I then applied a set onto the switches of the model I already have built and gave it a test run. It worked well! However, while "hitting the switches" I heard one of the motors making a wierd noise and took off the body to look inside the chassis. I noticed the plastic of the motor making noise was coming off and also noticed it was torn. I glued it with some super glue type of adhesive I use for photo etching. It glued the plastic piece but after putting everything back together and testing it, I noticed it was still sliding off the motor everytime I juiced up the motor. Here is a picture of what I'm talking about. It's circled in red.

Question is, is that plastic piece I drew in black and circled in red sold seperately? I've been to Radio Shake and a few other hardware type stores looking for toggle switches and motors but havent seen that piece sold individually. Does anyone know what might be the problem or will I just have to invent my own plastic piece or buy a motor all together?

As always, thanks to everyone for taking a moment of their time to read and/or participate in my threads.

Erm, first of all, I think you are in the wrong Forum. Try R/C. As for the part...I'm not sure the size, but from the picture I'm guessing the motor is the same size as a 1/32 4WD mini racer. Try looking in R/C stores or 4WD stores. I know that they sell cogwheels seperately.
BTW gluing won't help much even super glue will slip when the rpm is hyped up.

HTH,

I put it on here cause it concerns model building. Im not familiar with R/C cars one bit but this is one of those small motors used to simulate 1/24 or 1/25 model car hydraulics. Sort of like the ones Hoppin Hydros sell.

That is a pinion gear and you should be able to find a suitable one as a spare part for slot cars.
Take the old one with you and I'm sure they can help you find a new one that fits your need and set up.
