Anyone have ideas on what went wrong? Abuse:bang:

When the crank is broken off at the flywheel, my first thought (especially on a smaller saw) is that the operator had a habit of engaging the chain brake while the saw was still turning high RPM. I've seen a lot of newer operators do this. They *think* they're being safe by slamming the chain brake on when in reality all they're doing is putting more wear and tear on the saw.

Great point as I wouldn't have thought about that. I of course hit the coil but I think it may have survived it. This will be my first case splitting so any direction towards that would be great.

Also if anyone reading this has an IPL for this saw I would appreciate getting that greatly.

Any ideas on what a new crank might run if I'm able to acquire a used one?

From what I have ready OEM only. Aftermarket seems like a huge gamble after gong through this much work once I get there.

Unless your looking for a learning experience it may be more cost effective finding an used MS360 crankcase with good bearings either on ebay or on the classifieds here.

I would like to be schooled on this first hand so my plan is to replace the crank and bearings and seals.

P/C look great other than a little carbon on the piston.

I would save that crank for future use/trade. I have seen a couple broken on the other end. Might be worth something to someone trying to do a low-buck repair. There has been lots of discussion around here about rebuilding cranks. They can be pressed apart and back together if the mechanic is determined and patient enough.

I've heard of a place in Arizona that can restroke Husky cranks, but I haven't heard of any place that can do Stihl cranks.

Seems like Treemonkey and Wigglesworth are both both 'hooked up' for this. I could be wrong.

Motocross shops are experienced in crank repair, from what I hear.

Good point.

I was doing some searching of the old threads the other day, and ran across an old 'lakesideAndy' thread on stihl crank R&R. There are maybe better threads out there, but I found his informative. I didn't bookmark it, however.

I would say that's found in folks that have been 'schooled', but have no 'experience'. Hurts me to think about it. There was a thread some while back about 361 probs that were likely chainbrake overuse related.

It was late... I had been drinking too much...

I did buy a crank on evilbay so once I get a couple of other smalll projects out of the way I will start cutting my teeth on this:msp_scared:
