Converter with pump bushing failure

[mike diesel]

I've got a converter here that had a pump bushing failure. As you can see it got very hot and discolored the metal, even on the inside of the hub.





I cleaned it up with a scotch brite pad by hand but I still have some concerns about it. Measuring the hub, it is about .006" "shrunken" in the affected area compared to the fresh end of the hub. I also could not remove those other inclusions in the hub shown in the below photos. We picked up a new converter but didn't want to send this one away as a core. Would you guys be hesitant to re use this converter? Or does it need a new hub/cover?

I wouldn't use it. .003" is maximum clearance. Any more than that and you're taking a chance of the drive gear touching the crescent. You will lose pump pressure also.

Excellent, thanks. We will hold on to it for the time being and send it out for a rebuild.
