Welding a motor

[MachineAddicted]

Hey Guys

I was in south america recently to learn spanish. I am always very interested in metalindustry in other countrys. I asked the director of my spanish school if he knows some industry. He brought me to a very interesting place.



There was a machinist who repairs car starters and other motors. The motors have worn out brass bearing sleeves. Normally people replace just the sleeves. What he does is a little different. He just welds the shaft of the rotor to increase the diameter. After that he turns the shaft to fit it to the worn sleeve.

Ive never seen something like that. But some people have told me that is not so rare.

I've used Araldite in that way to fix a clothes dryer motor - didn't have a welder at the time.

I have heard of crankshaft journals being fixed that way. I fix a shaft in my garage door opener that way using my MIG welder. Worked great.
