A few times I have had to do this removal I just dropped a big washer, sized to fit inside the race and spot welded it to the race, won`t hurt the case at all, let the weld cool some and punched out the washer and race easily. Others have their ways but this is how I get them out without quickly.I do. I was thinking about conjuring something up with the mig. But I was also thinking that seems like a good way to ruin the case.
Whats your thoughts Pioneerguy?
Pioneerguy that’s what I’m thinking too.
I get the heating up the case part. Wouldn’t need map gas, these cases heat up rather quickly with just a heat gun. It’s a 372 btw. I’m not sure how I would pop it out after heating it though. Anything I could fit on the lip to hammer on it would probably mar the case. Am I wrong?
Funny, that is exactly how Husqvarna tech also does it. By the way it works. It's your saw, do as you like.I would not do that, that is why I spot weld the washer in place, let it cool and hit the washer, the race has already shrunk like mentioned and the race will come out very easy. The other mentioned methods may work but I like to get them out quickly and get on with the job.
I suggested welding the race above, once I thought over that's a bad choice. Oil soaked magnesium may be damaged with that heat.
A plain electric heat gun or propane torch should be enough heat, to expand the cases enough to loosen the bearing race. Dissimilar metals, mag will expand more than steel.
Is anyone else finding the site very so tonight?
