So long story short my buddy got scammed on a mini Revo so I've been slowly replacing all the torn up and worn out parts on it. One of the last things left is the motor. I noticed when you turn the pinion on the motor, every revolution it 'clicks'. My personal mini Revo doesn't do this. Motor is butter smooth when you turn it. I imagine something is broken inside his motor? It runs but it sounds hurt when it does.
Figures. This thing has been a money pit trying to make it right again.
This was all checked with the motor removed from the truck.Originally Posted by redemption
The pinion was jammed against the mount though. I had to pry it off because the set screw was stripped. Even the motor by itself still sounds rough in comparison to mine.
I had a similar problem, I have actually had dirt inside the motor. I opened it up and cleaned it out, and everything is good. Another possibility would be the magnet inside the motor leaving metal shavings, causing the notchiness. Pull the motor apart, and I'll bet you'll find the problem.

I'll probably do that once I find a hex driver small enough, lol.Originally Posted by Blone
