Can the cases be knureled ? Or maybe knurel or peen the bearing on the loose side ,they used to knurel valve guides in heads when i was younger
 
Its my belief that if heat is used to remove crank and bearings together the likelihood of enlarging bore is greatly reduced

You install bearings with heat and bearing installs with no problem

whynot use heat too remove crank and bearings

Yea, but....what weighs more? The wood your 7900 has cut, or the wax that polished it?
I dunno. Let's see... zero wax, and this much wood in this one load... umm, I believe the answer is "I have a potty mouth".

Does Glock powder coat cases?
Really? C'mon dude. If you need a price, just ask him.
 
Whats the deal Clint? U in a bad mood ? I dont need one powder coated right now but was only curious as to the going rate?
I didn't mean to sound grumpy, at all. I was just shocked that everybody on the forum didn't know Mike (Glock37) did powdercoating. I should've put a little smiley in there for you. :)

Give him a call, he's a great guy to deal with! I know how much he quoted me, but I didn't want to say the amount, and then have someone call Mike and get a different answer...
I like the looks of that wrap handle on that Dolmar....don't think my husky wrap handle goes forward that much.
I think that is a custom handle Clint welded up. Seem to remember him doing it on one of his saws, this one might be it.
That's a factory full wrap on my Dolmar. I welded the 3/4 wrap onto my standard 064 handle. I posted a pic of that one a few pages ago.
maybe his pt cruiser broke down?
Uh. I'm not sure how to break the news to you, but that is actually kevin, AKA @Magnumitis . I drive a 2006 Dodge Cummins... You can see a pic just a few posts above this one.
 

This looks like it's about to go down the crapper

Round nosed boat tail looks like that packs a punch too ...... What's the ballistic coefficient look like on that hog ??

yes that is what I sent him new OEM Stihl crankcase bearings
but the cases I sent you for powdering were all used so maybe it spun a bearing in its first life and that is why it was on my parts pile, who knows

The bearing is a tight press fit, to me it feels like 2-4 thou press fit. To sand blast off that much material you'd have to use a very aggressive media (which maybe Mike uses?) and really dwell on that bearing pocket (something Mike probably doesn't do). If the bearing locked up its possible it spun, which could definitely loosen up the seat. But I haven't heard of spinning a bearing. It would have to run really dry, and it's usually lubricated by the mix from the backside I believe. Straight gas would have a more immediate reaction from the piston locking up than the bearing. Still, anything is possible.

Trying to knurl the case is a good idea, but that will be really hard. I don't know what tool you would use to get in there. If it were me, I would get a sharp punch or nail and a hammer and dimple into the bearing seat wall with it a bunch. That might help tighten the seat up. I would also use red loctite to make sure that bearing doesn't spin.

Next time you break down the saw, if you're lucky enough that the bearing is still in there tight you'll have to heat the case up good to defeat the loctite and get the bearing out.
