My Disston DO-101 pics (I hope)

[Ranchero50]

Got a page at work to go check out the monster saw sitting in fleet maintenance today. Rode over and checked out the saw my friend brought in. It wasn't a two man, but is in pretty good shape. DO-101 with a disston 20" bar and disston chain still on it. The blue instruction decals were in bad shape and it had a farmer's carb conversion to a yellow HL-35 from who knows where. The price went up to $100 per saw because it's in such good shape but it has that certain sex appeal of an old monster. Spent a few minute with some old Kroil spray and got it cleaned up to presentable.

Didn't have spark either so I have that to overcome...

The first pic is a comparison od the DO-101 to the Holelite Super XL

The second is the right side shot showing the disston markings on the bar. What you can't see is the Mercury crect on the orange bar cover.

Here's another from the left side showing the covers.

A detail shot showing the ID plate. The top has Disston's info with the pennsylvania state crest and the lower half has the Mercury info with the crest of the company that made it (brainfarting bad on thier name)

I did start pulling the saw apart to figure out the ignition issues and clean it up. The piston has some minor scoring on the exhaust side, but has good compression.

Any good sources on the net on how to get these things back to running?

Hi Ranchero. You can get a new coil for the bendix scintilla ignition from this place http://www.oldmercs.com/ . It'll cost $50-60. If the coil covering is cracked, it's probably no good. I have been thinking of adapting an HL tilly to my 101. Could you take a closer pic of the carb and how it is mounted? Maybe Lewis can give you a link to his thread about fixing the fuel meter on his Disston. It was challenging to say the least. Here is a pic of my 101. It looks very similar to yours. That's a nice saw you found.

The carb is mounted to a flange that's brazed to a pipe and then brazed to another flange on the head side. It's a little cobbled together looking, but seemd to work, and it was hidden by the gas tank and air filter housing. The saw choke lever wasn't hooked up and throttle trigger gear was out of mesh with the throttle gear. It has just a universal lockscrew setup like a Holley carb manual choke.

I'm going to try and get it working again and hook up the choke to the factory lever.

I haven't gotten down to the coil yet, just taking my time and pulling it apart slowly.

Hi Scott.

I saved that pic on my computer when you sent it to me. Did you ever do anything with your fuel meter on your saw? I still have material to make those diaphragms, just send me the fuel meter and I'll make them for you. The fuel meter will probably need other seals replaced also, I used some "0" rings to repair mine as you could probably read from my thread.

Ranchero50. The diaphragm material in those old fuel meters will not stand up to the newer fuels we use today. The fuel will eventuall destroy the old diaphragms. I had to replce the top 2 diaphragms and some seals inside mine. A challange, but at least she runs. Do you have the Owner's Handbook and Parts Manuel. If not let me know and I'll send a PDF copy of them to you. Take care. Lewis.

Carburetor:

OK, I take it that the old Disston has another carburetor adapted to it. I was considering doing that, but decided to try and keep her as original as possible. I'll supply as much help as I can to help you get her running if you want. Just email me on what your doing and what you might need. Lewis.

Lewis, I got a saw and nothing else yet. There are several other saws in these buildings and a bunch of parts. I'm going to try an hook up with him and go check them out instead of buying saws peicemeal. He said he tripped over an ancient homelite trying to get this saw out (in the dark in an old knob and tube powered outbuilding). I'd love to get the owners manual from you if you have the bandwitdh to support it.

Well, keep us updated on what you find/buy. that disston looks real nice.
I just dont understand this one little detail, if the saw is direct drive, why is the starter set up to turn the engine clockwise instead of counter clockwise?

 

[Mange]

I think it is a gear drive. :alien:

 

[Lawn Masters]

Oh, so it is. I wonder how I got to thinking that it is a direct drive model.

 

[Mange]

I could be wrong, that is something I am regularly

 

[Lawn Masters]

you're not wrong in this case, Mikes site says gear drive, as I'm sure Lewis will be able to confirm.

 

[Mange]

Ok, that was good to know. I was thinking about the colors of these saws, were there different, different years or is it something else?
I like the orange better

 

[Al Smith]

Well gents,it takes a lot of grit,and iron will,to restore these old relics.How well I know. On occasion,I have had to walk away from a frustrating problem,for several weeks,until I clear my thoughts.So far,my success rate is 100 percent.You will get it,hang in there.

Patience and Percserverance:

Well said Al. Been there done that. The biggest thing I find to do, is to step back, look and think about what you are trying to do. Use a bit of common sence and proceed with the project. It's harder if you have no materials to work from, so you have to rely on your own experiances and a bit of advice from others.

Ranchero50: I do have the Owerner's Handbook and Parts book in a PDF format. The Owner's manuel is 2.47 Mb's and the Parts Book is 1.79 Mb's size. I'll send them to your email address. So be watching for them. I'll send them out this morning. Take care. Lewis.

Paint and Decals:

Ranchero50: As far as the paint thing goes, I'm not sure what to say. Some of the saws were painted as I painted mine. Disston Orange for the gas tank, side cover, air filter cover and handle. Others were either painted a gray color (like a dark gray primer) with an orange handle like Scott M's saw. I'm not sure how it went as the saws were produced. I believe the earlier ones were painted and as the company was headed for it's final days in existance they cut expences and painted less of the saws. This is just a guess. What is the serial number on your saw. Mine is 618081 and it had signs of orange paint on the side cover, tank and handle. I've have not been able to get info on the serial numbers and paint schemes as the saws were produced. OK, hope the manuels help. Take care. Lewis.

Manuels are Sent:

Ranchero50: Sent the manuels.

Mange and Oldsaw-addict: The old saw is a direct drive gear reduction saw. If you open up the PDF parts files on the Samlaren/forum you can get an idea of what the clutch and gearbox assembley looks like. OK, take care. Lewis.

Hi Lewis,
I saved your thread that gave the sizes of the o-rings and such. I guess I should try to rebuild the fuel meter before adapting an HL. I might take you up on the diaphrams. It will probably be a while before I did into it.
