That chain on my 111i is a .325 that came with the saw.   It is a 18' bar and the chain is a chisel.   It is one of the chains that I converted to square grind with the gray wheel.

That is alot of different models all using the same pump.

I think the pumps are pretty much the same through those twenty years but the drive is different. I notice in this pdf they are saying 1994 was the change point for the drive set up but in another ipl they are saying Dec 1996.

the mufflers are rather restrictive. didn't want to take the muffler off tonight, but hee's some pics of the 'deflector'. when you remove the deflector, it's pretty straight forward what needs to be done. :) the paint is smudged on the muffler and makes it look like it's squashed. it's straight as an arrow :)

Mine was originally .325 8 pin and in the picture is the original 15" X .058" bar which I quickly replaced with a 18" bar with Carlton chisel chain.

But now I have 3/8" X 7 pin rim on it. The bar was a .325 but I put a 3/8" nose on it. The bar is 16" X .050 and the chain is 59DL.

no. but i do have a stihl screen to put on the tube if needed. haven't used it as of yet, not really worried about starting fires on the swamp in the winter or out in the yard blocking wood. :)

I sharpened the old style Oregon semi chisel chain without the extra bumper on every other DL last night and took the rakers down where they ought to be. All the top plates are not completely cleaned up as someone filed a half dozen left hand ones at 40 degrees.

Sawed with it some this afternoon and it cuts like it should.

I have the mixture set at 12700 free running at where it four cycles. It cleans up nicely in the cut. Sure seems to carry a lot of rpm in the cut like my Dolmar 6800.

In spite of all the goody talk about old Dolmar rpm, keep in mind that these figures are down a thousand from a 346.

Needless to say, to have a 6800iH and 115i pair out in the woods would be a fine combination. Your dog would not be ashamed to be out there with you.

The Ole 6800 (new style Dolmar 120Si) started right up, first pull, with the choke on after setting a couple weeks.

i can let that 111i sit for a month or 2 and she will light off on the 3rd pull and be happily running on the 4th. if it's started regularly (if i'm using it) it'll go on the second. it pulls the chain almost as good as the 5105.

When playing with the clutch on the 111i family of chainsaws, the ones with rim sprockets have two different drive set up for the worm gear. Not exactly sure when the change over date was but one ipl proclaims 12-96?

The old worm is metal and the new one plastic. The plastic one has a shadow of the end the clutch hub on the outer end.

The hub of the new style clutch drum has a counter bore that extends over the shoulder on the end of the crankshaft to engage the oil pump worm.

The old style metal worm is a interference fit on the crank and this oil pump system is full time, even when idling and the chain not running. I've had saws like this and you would not notice in normal use.

The new style oil pump drive has the plastic worm with a sintered bronze Oilite bushing inside that floats on the crankshaft and is driven by the hub of the clutch drum. This oil pump only works when the chain is spinning. Possibly a EPA thingy?
