Sachs Dolmar 116 barn find

.325x.050 rim sprockets are quite common, however IIRC the 116 used a spur. No matter they are all over e-bay or you can get an oregon replacement from baileys or the like.

 

325? not original to that saw .375 is standard 3/8-.050 that it came with. Bar is not the same slot size as current Dolmars, Husky bars fit but I forget which one.

 

Found a deal on the dolmar branded bar and went with it. I run aftermarket bars on a couple other saws. I was just trying to get this one back to sort of original.
I wasn't sure if shaft size was specific to certain brand saws for finding the correct sprocket. This one has a rim type sprocket, rather than the spur. I may shelve the dolmar bar for now and throw on a different bar. If I do get a new sprocket, is there anything for improvement on getting a 7 0r 8 drive for speed or torque?

 

7 is standard

 

Thanks
