[SOLVED] SOLVED: Sticky "gear" on Dash robot

[gtwtech]

I'm trying to repair a sticky wheel on a Dash robot. I took the entire robot apart and located the issue - not sure I would describe this piece as a gear, but it connects to other gears. When spinning the wheel by hand, it will not spin fluidly like the other one - it spins, but feel like there's a bit of resistance and stickiness. However, I cannot see a way to take this piece apart and fix it. Pictures are linked below.

Any suggestions? Apologies if this is the wrong forum location for this question.

The stickiness being in the motor shaft?

I would try some powered graphite applied to the silver shaft and see if the graphite powder would work down into the motor and free up the movement.

If you do not have powered graphite available then just rub a pencil "lead" on to the shaft next to where the shaft goes into the motor.

Do so on both ends.

I like the graphite Idea, or a teflon based lubricant, too (shake well).

NOT WD40! It will eventually gum up your motor.

More than likely, though, your motor is totally <<snip>>. If the lubricants don't work, then pry off the gear and take the thing apart to see if you can fix. Look, it doesn't work, so you can't make it not work worse.

Bottom line, I'm sorry to say, plan on getting a new motor.

This worked! Thank you.
