Motor "popped"

Hello,

i've got a 9L which...well...popped on me. At first I didn't realize it but then it skewed which must have caused the motor shaft to put extra pressure on the bearings b/c it was like driving with serious brakes on. I finished the heat but now the motor rattles horrible and the can pops open every time I try using it.

I was thinking, if I replace the bearings AND use one of those super cool heat sync/holder things will that keep the motor together an useable?

How tight should I make it?

Thanks guys.

MacII
