Broken case repair demo

[Freakingstang]

I tend to think these things break off more from being thrown around in the back of trucks vs. cutting.

I honestly think, it had something dropped on it, like a small branch or something. It didn't have a dual port on it, and the muffler was the newer smaller hole variety. It also had the handle bar replaced when I had gotten it. The saw always ran great, and I don't use dawgs on most of my saws, so I never really worried about it.

Still a good thread Brad. Let us know hold it holds up.

it had good bearings in it.....lol

BTW, the bearings were good. No surprises in anything you sold me. Everything was as described. Actually there was a surprise. A good one. The bearings in the parts 084 were fine, just dirty.

JB Weld

Maybe everyone knows but regular JB
Weld is good to 500 deg F, the 4 minute only to 200.

So I'm good to drop this thing in the oven at 300F before sliding it on the crank?

Just a general knowledge thing on JB Weld, I dont know what kind you used.

I used the regular. I'm just asking, is it OK for this to soak in 300F heat for 20 minutes? It'll likely get that hot from the muffler.

Well, I guess you've got a plastic crankcase 084 now, eh?

Brad, you are okay, just hoping folks can learn from my not so fine first tries.

Hey Spacemule, that would be Space polymer

Brad, a few other Loctites:hydraulic/pneumatic/post assembly(also good for sealing cracks)/ one just for bearings/ one for studs. Go to the website.

That's interesting. I have an 066 crankcase that's broken in the exact same place. I intend to fix it in a similar manner.

The only thing I'd do different is to add one fender washer if there was room. I don't think I'd put one on the spike side, but would on the bolt side.

I realized that when I was processing the pictures. Too late now


Yes, I split them. I had the whole gasket kit, so why not. It was easier to get all the old oil varnish out of the bearings and make sure everything was clean this way.


With any luck, this saw will be running Saturday or Monday, since I'm off Monday. The 084 is finished except for the plastic covers. The other parts 084? Well, it's not a saw anymore It lost what few good parts it did have to the "new" 084. About all that's left is the bare case halves, the flywheel, and the oiler.

I think the two screws (rebar) used for reinforcement show up in your second picture...looks like a couple of stainless screws to me.

Nice work, Brad.
Davefr's idea is indeed a good one imo ; I think that additional mod had made it perfect.

good job

Good job, that is what my 066's case looks like now. I think mine and yours turned out well. But I didn't split the case to fix mine.:greenchainsaw:

Great thread. I will try to diplicate the repair on my 066 RL. Will post pics
