Title: Dolmar 116si
Post by: Cut4fun . on August 25, 2013, 09:30:08 am
Guy I know through internet only sent me a video of his dolmar 116si cutting up some firewood. He lives maybe 40mins south of me and is a member here but dont have a youtube account.

A 116Si and a Dolmar 6000i use the same piston and cylinder but the brake is a little different

The 116Si is 60cc and the 120Si is the same chainsaw with 68cc

Jim is the 116si as heavy as that 6000i?

Maybe slightly more so?

The main difference with the 116S is there is a pressed on worm for the oil pump drive so it has a full time oil pump instead of one that only runs when the chain is spinning like on the 6000.

I think this was more of a EPA thing than of any real usefulness.

The oil pumps themselves on all the Dolmars in the last 20 years that you and I would be using are the same design. from the 111 to the 7900.

The 111/115 also changed to part time oiler when the 6000/6800 came out in '97 and the 116S/120S was discontinued

In '99 they made the 111 the same closed port cylinder as a 115 and I think that was the end of the 115?

The 116S, 120S, 6000, & 6800 all had  the same 36mm stroke as the Husky 365 Special and 372XP but the bores were smaller.

The closed ports on the Dolmars were of the old style upper and lower window design using a windowed piston. The lower transfers were not in the base flange area of the cylinder and crankcase. Some of the Stihls were this way. You cannot do as much porting on these as all the port dimensions, piston skirt width and lengths were all mathematically worked out to coincide with the port spacing on the cylinder. They ran pretty good they way they were.

Thanks for taking the time to upload and posting that link for me.

Just a stock 116si, with a 16" bar, 3/8" full chisel 7-pin. Probably had a tankful through it before I shot this, so not a fresh out of the box sharpening. I like to run my rakers in the .045-.050 range, and thats about what these are. The wood was Ash, about 14-15" at the big end, tapering to 11-12" by the end of the vid. I am no racer, this isnt a special video or anything. Just the way I cut and run my saws everyday. I have a soft spot for the 116si and 120si.

660mag...you seem to know more about these old dolmars than I do. I have a few 116si's that are ported, and your right, wasnt much that could be done. Just a tad wider, and really just smoothing out casting lines. The few I did, I raised the ports just a tad too, to compensate for taking the base gasket out to get squish down to 0.020-0.025.

Thanks again for posting that for me Cut4fun. I really appreciate it.

The 116Si usually had a Kobelschmidt cylinder whereas the 120Si cylinder was a Mahle. But they were identical except for bore and the fins being slightly larger on the 120Si. The external fins varied on all these cylinders over the years. There were ones with and without fins under the exhaust ports and there were some with the fins removed to the left of the spark plug to allow room for the spark plug wire.

The piston cylinder sets for the 116S/120S were interchangeable but are no longer available. There is a guy that frequents this site that has some new old stock pistons for the 120S/6800 available.

Be careful comparing the 116/120 with the "S" versions as there were differences.

Post by: LD1 on August 26, 2013, 03:37:12 pm
Never ran anything but the SI's. I imagine the supers were good runners too, and would snag one in a heartbeat if the price was right. But the 116/120 non-S versions dont interest me.

I wouldnt mind having a 114 and a 119 to round out my collection, but dont see them that often. And I hardly ever use my 112 or 117. The 117 is quite strong, but its no 116SI. And honestly, the 112 reminds me of a 029, overweight and slow :)

My go-to saws are my 115i and 540 for trimming, and a pair of my 116si's for bucking. And I'll take my 6400/8400 along if I know I'm getting into some big wood. But dont use it unless I have to. Its easier to maintain 16" B&C's than a 24". I really do have a soft spot for the dolmars ;D

I forgot to mention that I love the sound of the dolmars. Especially the older ones, and even the smaller ones. The stihls and huskys are just too "high-pitched" for me. I like the deeper tones and throaty sound of the dolmar.

Those are some good Dolmars to be going to. I have the 115i, 5105, 6800, & 7900 . . . That gets the job done.

Thats a good combination of modern 5105/7900 and old 115/6800

I have never laid hands on the 5105. How does it stack up to the 115i?? I know the 116/6000 and 120/6800 are every bit as fast as the modern 6400. Just wondering if the same can be said for a 115i of 540??

And what is that additional on-off switch on that 6800?? IS that something you added, or were the 6000/6800's like that??

The situation with the 5105 is that it has a 1,000 rpm on the 115 and just as much torque. A 5105 has a catalytic converter in the muffler. These converters are heavy. I put a 5100 muffler on my 5105 to eliminate the catalytic converter. The 5100/5105 has a inboard clutch and the rims and chains are easy to change. But this makes them a little wider and heavier than a Husqvarna 346 New Edition. But they are right up there with power.

My 6800 began life as a 6000Hi. I changed the piston and cylinder to a 6800. The "H" in the nomenclature means that it has heated handles and that switch is the switch to turn the handles off-on. My 7900's do not have heated handles but the switch for heated handles on that series of chainsaw is on the right side of the rear handle just like the ignition off-on switch is on the left side of the handle. Husqvarna 365/372's are the same way with the heated handle switch.

Heated handles...duh!

Yea, cut4fun was telling me about you swapping to the 6800 top end. Do you notice much difference in it after the change?? Cause honestly, I never could tell much difference between the 116si and 120si in your average 14-15" wood. I never really timed them in the cuts, but they felt the same. And anytime I was into bigger wood, I'd grab the 6400/8400, so never really had a bar burried in 20" wood either. I dont have a 120si anymore. I gave it as well as a 116si to pops. So now he has a PS6400, (2)120si's, 116si, and a ps350. So I guess you can say it runs in the family

The 6000iH was a sweetheart of a chainsaw and all I can say is - that as a 6800, it is still a sweetheart.

In 18" wood and timed cuts you could probably tell the difference?

Mine has the original K095 mount 20" bar that appears to be a Dolmar branded Oregon Power Match bar. I've always had Stihl RS chain on it.

You will possibly come across a 116S/120s/6000/6800 that uses the D009 bar or even a Stihl bar as someone has changed the bar studs? The kit numbers for these was 010 232 010 for Stihl studs and 010 232 020 for the D009 studs to use large mount Husky bars.

My 7900's have 24" bars that are D009 mount Dolmar branded Oregon Power Match bars. I have a spare 28" Oregon Power Match bar for these.

All of mine are the original K095 mount also. But last time I bought bars for all of the 116si's, baileys had some carltons on clearance for $5 each. Nice sprocket nose bars. But a different mount. Allthough they were similar enough to use. I think the stud slot was a llittle bigger (no big deal) but the tensioner hole was too far away from the stud slot. Nothing a little burr in a die grinder didnt fix.

The Dolmar 111/115 are good saws in the woods.

I picked it up. Working on pics.
NIB is only thing that would be in better shape IMHO

Yep SOLD already. 

Runs as good as it looks. Crappy chain but sweet running saw.

Had a sachs dolmar LP bar cover on it so gave new owner a 20" 3/8 bar cover instead.

Same saw as the 6000i except the brake mechanism is different inside. Other saws of this family are the 120Si and 6800i that you are familiar with.
