Jonsereds 110/111/111S Thread

[bulletpruf]

All -

When doing some research on the Jonny 110/111 saws, it seems that the info is spread around all over the place. I'd like to start a thread to try to flesh out what we know already and consolidate the data in one thread. This thread is cross-posted in a few different places in hopes of reaching all folks who may have info.

First, starting with the 110, I believe production started in 1972. It's a 110cc saw, listed at 20.25 lbs, powerhead only. The 110's are quite rare, and all had a one piece top cover.

I have one, maybe two 110's in my collection, but only one has a serial number. The other does not have a serial number, and it could be a 111.

This is my 110, serial number 701058. It's the 110 listed on Magnus's site that has a serial number -







I'm fairly sure the 110 was a one-year only saw. It was followed by the 111, likely in 1973. I believe the 111 was also a one year only saw, but perhaps it was manufactured for 2 years. I'm not sure of the differences in the 110 and early 111. However, I believe the late 111 saws came with a two piece top cover.

111 with one-piece cover -


111 with two-piece cover -


The 111S is the most common variant. I believe production started in 1974 and went until 1980. This is another one of mine - serial number 717131 - the only one I picked up in Europe. This is also the latest serial number listed on Magnus's site.



Please post if you have saws, info, details, etc.

Some difficult to find parts on the 110/111 saws -

Fuel tanks - prone to springing a leak.

Oil reservoir cap - very uncommon 2.0 x 1.75 thread. I haven't found a good option/substitute here. I need a few of these; not sure if it's worth trying to have them reproduced.

Mufflers - not many used ones available, especially not good ones.

Air filter covers - 111S - there's a shortage of these. I've been looking for one for months. Again, not sure if it's worth having these reproduced.

Pistons - no reproductions available, but some have theorized that a Dolmar 166 piston will work. I have both at home; I need to compare them. Uncle Lee @leeha may have some very nice new 166 pistons left.

A few other data points on these saws -

I have seen two different variations of the felling dogs/spikes. One is quite long -- perhaps for west coast saws?



I don't have any pictures handy of the other dogs.

And there are at least two different types of full wrap handles - I believe the early one had the hanging leg terminating fairly high up.


And the later one had a hanging leg that terminated lower and with a curve. Perhaps it was less likely to get caught on stuff?



Here's a question - does anyone know if Jonsereds supplied the full wraps? Or were these added to saws after they were manufactured and shipped?

Great info Scott. Finally got my first 111S. Now I need to find a way to fix, or replace this tank...as it has seen better days!!


Don’t thing fuel is gonna hang out in here long...

Bumping an old thread. The 110 cases are marked with a cast S. The 111/111S cases are marked with a cast S1. There are a few other differences, but this is the easiest one to spot. I have verified that one of my saws is indeed a 110.
