Good evening! Thought I'd share my latest chainsaw gadget, that I'm looking forward to using for maple sugaring in a few weeks. I like this kind because, unlike most others I've seen before, it doesn't use a toothless chain to drive it. It fits right over the rim drive splines on the clutch drum. I've only seen one of these once before and it was years ago, so when I saw this on eBay I snatched it up right quick. The seller had it attached to a newish MS261, and I got the package for what would have been a good deal for just the saw. I have a nice 026 that I'll be using with this, so the 261 is being sold after I get it back to chainsaw configuration (more on that later). As there are NO markings of any kind on the gearbox, I'd love to know more about it if anyone has any knowledge. It appears to have been made in a very small run, maybe in a factory machine shop. It appears that the pattern for the casting either didn't come out as expected, or the sand mold was worked on freehand a little bit.
3/4" chuck
Look carefully, and you can see the crappy sand casting work done. The case is aluminum.
Chainsaw side. The kadingus toward the fixed vise jaw fits over the clutch drum splines. It appears to have been made very crudely with a milling machine, rather than broached or investment cast, again indicating that this was likely made in a very small run.
Attached to saw
Method of attachment to saw. Notice the broken bar stud.
Oil tank on the 261. Apparently this saw was purchased new specifically for use with this gearbox, and had never had oil in the tank. I was afraid the oil pump would be burned up, but it oiled as well as I've ever seen a Stihl oil.
I'm thinking of giving the eBay seller some crap, because he waited 18 days after receiving payment to ship the saw, and although it was advertised as "good" condition, it had a broken bar stud, missing clutch pilot bearing, missing bucking spike (or whatever it's called), and the part of the cover that the master control lever slides in is broken and bent such that it prevents the lever from moving freely. When the parts get in I'll test run it and then hopefully sell it. I may eventually buy a 2nd 026 and remove the oiler and brake, and make it a dedicated drill engine. We'll see. In the meantime, it will go on my current 026 and be used to start the engine on my welder, which was made in 1956 and has no starting system whatsoever, not even a rope start. Just a big nut on the crank stub. That way, I'll be able to start the welder in places where I can't plug in my 5/8" electric drill.
