Chainsaw Repair

Support sent me a link to lost post.

660mag  Appears to be a early model Sachs-Dolmar 109, 110, 111, & 115 family chainsaw. These were different displacement variations of the same family of chainsaws. Some parts will interchange between the different models. They all look alike. 1989 ish

660mag  The 111 & 115 are 52cc or a little over 3 cubic inches. In the early models, these two differed by the 111 had open port intake transfers and the 115 had closed port transfers. 44mm bore

The 109 & 110 are 43 cc. They also differ by the open and closed port transfers. 40mm bore

660mag  Of course with chainsaws this old, whichever one of the family it was originally may have been changed over the years? This family of chainsaws was continued up until 2004 or so and there are even blue Makita variations of the saw.

Warped5  This saw is a Sachs Dolmar 112 ... 51cc.  I have a clean one that I had ported by a fellow on the Cumberland Plateau.  Runs very nicely.  Here's a link to the info on the Acres site:

could very well be except the air filter cover doesn't attach the same way? The primary air filter is shaped different..


prsiler Ha! That was the first time I've used photo bucket, so the slide show thing was an accident. About the saw, the brake is missing and it needs a carb kit. He got it in an auction with some other saws and asked me to look at it for him. I need to find out how much the brake parts would be. It runs right now but needs the carb kit but if it needs a top end are there big bore kits for it or do top end parts from that family of saws interchange? Other than pulling the jug and measuring the bore is there a good way to figure out the model, like numbers cast into it somewhere? Thanks for the help.

Remove the muffler and look at the piston to make an evaluation. A compression check would help evaluate? Might only need rings?

Some had Walbro carbs and some had Tillotson carbs

New cylinders are difficult to come by. Occasionally used ones show up. New pistons are available.

The 44mm bore was probably more common. There's a 45mm open port bore but not very common and not as much power as the 44mm closed port.





RoyM They were very good saws, I am keeping my eyes open for similar locally. Parts are getting scarce and rather expensive, you might do better looking for a donor saw.
