Disclamer: Going to document building up a 036 from bare cases. I have some other stuff to share. Might take a couple weeks. I see a lot of info on splitting cases but not much on putting them back together. Hopefully this info will be helpful to someone. First time with splitting cases so I am learning as I go.

Now that is over, background, picked up a "mostly complete" 036 parts saw from another member. Mostly complete is a loose term. Sourced a lot of the missing parts from the net. Biggest issue is the crank and bearings are shot. Stripped the case and got the old crank and bearings out. A picture of the cleaned cases will be attached. That part of the project is on hold for parts arival. A new OEM crank was over $200 so I went to HLS Supply for an aftermarket crank. Measurements are spot on and it looks really good.
Picked up second complete running saw with some disclosed issues from another member. This one is a 036 Pro, working on that one now. Some pics of the carb build will be put up.

Old crank on left, new on right.

Cleaned cases, staging parts for build.

The jug on the right was ported by someone for the previous owner. Looks like the exhaust was raised a bit. The saw has an air leak I believe and really pulls some rpms. It hangs for a second and 4 strokes and then it absolutely takes off. Put a different fresh built carb on and got the same issue. I can't correct the issue with adjusting the carb. Compression on that jug is down to 118lbs, might be due in part to the raised exhaust?

Complete 036 Pro that has some running issues. As mentioned it was ported for the previous owner. The exhaust side at least was not completed. The muffler has the stock opening.

Work bench I just finished so I had a warm place in the house to work. Shop is getting really cold!

Flywheel puller that I made up. Turned the threads on the end of a piece of 1/2 black steel pipe. I welded the 1/4 flat stock to the other end of the pipe then drilled and tapped it for the center bolt. The center bolt was turned to make the point. I used 1/2-20 threads for this. Threads right into the flywheel and works great.

Thats it for tonight. I will pull the jug off the 36 Pro tomorrow night to get some shots of the "porting" that was done. Hope the jug is not junk but the way it is running I have to wonder.

( think I got the right part of the quote) I experienced an unfortunate result with a homemade flywheel puller... it split the crank on a " like new", but obsolete saw. Anyway, when I built my puller, I put a very gentle point on the bolt in my puller. Just a thought. Your puller looks real good :)
 
Nice work!

Yes sir! I'm watching carefully as I also have two on my bench in similar states that are my current projects. Fortunately, the cranks both seem cool. Bearings are another story on one with the other one being about halfway rebuilt by another member here before I got it from him.

Do you have one pro saw and one non-pro? A lot of the parts are different. It will be a little frustrating when you put them back together. Tell us as you go, how much difference you find.

The only difference is the Pro has a comp release and a different top cover to accommodate it.

Not on the one I did. The case is different. The oil pump is different. The starters are different. The carburetors and air filter were different. The mufflers were different. The clutch and cover for the chain brake was different. This was an 036 and an 036 pro. Maybe the ms360 is like the 036 pro, but not the 036.

Case for both is 1125-020-2120
Oil pump for both is 1125-640-3201

Various components changed over time and design, but are mostly interchangeable. Your 036 may have been a real early one, but for the most part the 036 and 036 Pro are the same saw except the de-comp aspect.

At least that's what my IPL says!

Cleaned up a bunch of old sawdust and oil etc. Got the jug off to find a suprise! This was sold as having an aftermarket top end on it. No AM, it is all OEM. I definately think I found the source of the air leak. The brown stuff on the bottom of the jug was what was used as a sealer I guess. It was hard as a rock. I have never had such a hard time getting a jug off before. This brown goo was more of a cement and had gone into the threads of the jug bolts. I sheared off the T27 tool that comes with new saws. Got the last one out with my regular driver and some taps on the end to help brake it free. The prior owner had paid for porting. The piston was cleaned up a little, nothing major. The lowers were blended ever so slightly. No work was done to the upper transfers. Intake and exhaust were worked on a bit. Nothing really special with the work. Actually kind of rough finish let by what ever tool was used. I am going to port match the muffler which was not done. Also going to try to clean up some of the work that was done a bit.
