I have an Integy Tire Truer.
I tried to service it because the motor seems to bog a bit sometimes. When I tried to check the plugs, the plastic screw cap holding the brushes in the motor just broke in little pieces. I tried checking Integy's site but they don't list parts for the Truer. Their phone number is also non existent on the contact page.
It seems like its some sort of industrial type motor thats not proprietary to Integy. Does anyone know what brush caps are compatable with this motor?
