So I got this 181 the other day from a guy that said his neighbor had a strong but dirty saw that he wanted to sell. It apparently lived full time in a toolbox in the back of this guys work truck and was only used to clear the road when a tree had fallen blocking the road. He was an equipment mechanic for a logging outfit. The serial tag was gone and "Stuckys Saw Shop" was engraved in it's place. It was filthy. Being near the beginning of my journey of becoming a chainsaw expert tech and general guru, it did not occur to me that if I was to come across a saw that was extremely dirty and oily, that it might be leaking oil from somewhere. I believed that it was a result of years of never cleaning the saw. It fired right up and had plenty of power so I figured all was well. Last night as I was scraping off what in some places was close to a quarter inch of oily dust, I uncovered a crack/s in the crankcase. I talked to the guy that knew the guy that had the saw and he suggested drilling holes at each end of the crack and using JB Weld on it. I don't have a problem doing that but I have to believe, even though I am in my earliest of days of my self directed saw curriculum and am not even close to an expert as of yet, that this case is beyond the JB Weld fix. Pictured below I will insert 3 pictures of the crack/s. I do not know which end is the beginning or the end but I will begin with the crack on the front of the case and work backwards.
This first picture shows how the crack goes from the upper front center edge of the right half of the case and runs behind the muffler bracket.
The second picture show the crack continuing on its journey moving downward and joining a bigger crack that rounds the corner ending at the bar stud.
The third picture shows where the crack picks up where it left off and continues on the other side of the front stud.
Does this look like a job for JB Weld? My guess is no. So I am going to put aside this saw for now until I acquire another 181 Crankcase right half. Maybe there are others out there with more experience that may have a fix that I am unaware of. I am assuming I should keep watching ebay for the part and post a want ad in the want to buy section of the forum, which I have done and can be found at https://www.arboristsite.com/commun...81-crankcase-right-half-urgently-need.317317/
So from this group I am asking for advice whether to,and if so how to go about fixing it, or the best way to find the part, and if I find the part, I will then inquire about all the things of tool recommendations and techniques for case splitting, bearing installing, crank installing etc, etc, etc.
Thanks for your consideration
