McCulloch Chain Saws

[belgian]

I've been pretty busy getting my house on the market so I haven't been able to spend the time I would like at my shop, but I will have some time soon I hope to make some videos. Still there have been some additions. Here is my updated Mac list.
Super 797w101B kart motor (123cc)
Super 797 (123cc)
Sp125 (123cc)
Cp125x2 (123cc)
73 (120cc)
890x2 (103cc)
790 (103cc)
550 super (99cc)
super 55A (87cc)
super 44A (87cc)
1-10 (54cc)
Titan 57 (56cc?)
33 (54cc)

Good to see you back in da house, Hoss.
According to Mike Acres list, the 550S is 103 cc, not 99cc...

Well I never really left, just haven't had quite as much time on the site. As far as the motor size of the 550S goes, I guess i'll just have to controll my dissapointment that it is actually BIGGER than I thought.:hmm3grin2orange:

Here are some of what I have. From top to bottom 660 geardrive,
Super 250, 650 geardrive, D-36

Did all the 650's come with that painted yellow bar tip? Is a gear drive fun to run and are all 650's gear drive?

They had black or yellow tips, 650's are all geardrives.
Yes there fun to run. There not real fast but there real strong.
Push as hard as you want on them and they just keep cutting.

Can parts be found?

 

[heimannm]

Briantutt- Depends on what parts you need. If you are a purist you may have trouble finding the exact OEM items like the sawdust screen etc. but the engine shares many common items with the other saws in the 200/250/300/380 family that keeping one going is not a problem. I have not had to work on the gearboxes yet but I suspect parts there would be more difficult to find if you needed gears or a shaft. Bearings and seals are common items that can be found at most competent bearing supply houses.

Hi Fellas
I know this is the wrong place to put this, and I should know better. Would any of you McCulloch guy's have a service manual for the Mac 15?
Many Thanks
Lawrence

Lawrence - I don't have a service manual for the Mac 15 but I do have one for the 1-40/50/60 Series saws that would be about 80% the same.

What information in particular are you looking for, perhaps I can scan the related pages and send them to you electronically.

Contact me by PM with an e-mail address if you are interested - word of warning, it will be next week before I am back where I have access to the scanner.

Brian / Cliff - I have an IPL for the 660 dated 1967 I think that show the black and yellow tip bar with the McCulloch logo like this one.

Yeah my IPL's are showing the same kind of logo as in your pic for the 660.
The 650 that briantutt asked abot has the painted tip.
When I got my 650 the bar had the yellow tip.

This one on the cover shows the black tip.

Hoss, could you do me a favor please and measure the bore and stroke of your 550S, and tell me what carb is on it ? I have a kind of mystery saw and am left with the feeling that Mac maybe pulled some tricky marketing stuff.



Mark, could you do the same for a regular 550 ?

Thanks in advance.

New Pro Mac 10-10 Auto pick up with questions

Well, picked up this Pro Mac 10-10 Auto last evening for $65.

(600013 U)

I asked the guy to fire up the saw. Started on the 3rd pull. It sounded great. He showed me the chain brake working. I asked him how much he used the saw, he said "not much." He uses Sthils for the most part to do his cutting he said.

I then asked to go over to his wood pile and if we could cut a little wood. We did and it was clear the chain was very dull. I guess that didn't help me determine anything. I fired up the saw myself next, started on the first pull with no problem. Hit the manual oiler once. Everything appeared ok.

I noticed on the oil cap (see photo) there was a little "sitting" oil it appeared. I asked him about that and his response was something about a air hole in the oil cap? I looked for a hole or crack but didn't see either. I really didn't know either way.

So I asked a few other questions and then bought the saw. Set it on some papers in my trunk and drove an hour home.

Much to my surprise when I arrived home there was a 6 inch area under the saw with light oil markings. :censored:

Couldn't tell if it was directly under the oil cap area or what. Any thoughts on this? Potential reason for this?

Regarding the bar, looks like the original bar is still on the saw? Would it be a good idea to put a new one on?

Also, the air filter had teh MAC stamp on it. Does that mean the air filter is original or can you still buy air filters with the Mac stamp?

Last pic:

Has a 16" bar. Does anyone run 18" or 20" on their 10-10? Bad idea?

Thanks for any input!

I have a Mac 10-10 Automatic that likes to mark its territory also. There is a rubber duck-bill valve located inside the oil cap. It sounds like it has failed as it is a one-way valve, and oil coming out from the vent hole is obviously going the wrong way. There are other possibilities for leakage, such as the oil tank gasket itself and the sealing washer under the head of the screw that holds the oil tank cover in place.

There are a lot of different IPLs for the 10-10 family of saws. Remove the air filter cover. There should be an ID plate mounted onto the floor of the air box, right in front of the carb. You will need those numbers to insure you order the right parts. Use the 2-digit number on the bottom row, left-hand side, of the tag along with the upper number. Then you can search for the correct IPL. For example, mine is a 14-600002U.

Thanks for the reply. I'll have to investigate the oil cap valve/washer, etc. I hope it is one of those issues instead of the oil tank gasket. One thing that makes me think it might be the valve or washer is that I saw oil on the cap when he first picked it up when I arrived. So, if he carried it out of his garage to set it on his front walk (he had it ready when I got there) it would make sense that oil moved during that walk?

Or, maybe he fired up the saw prior to me getting there and moved some oil around?

Did the oil on the cap look fresh like it had just came out of the jug, or did it look like it had dirt & sawdust mixed in it?

I would think that it would be a wise idea to make sure a saw will start before a potential buyer comes to look at the saw. Nothing like telling someone how good a saw runs while you are giving yourself a one-armed workout. You, as the buyer, would have to feel if the engine felt warm before it was started in front of you. Just be sure you don't just blindly grab the muffler and potentially roast your fingers on it.

I really don't think the guy used the saw too much at all of late. The chain was VERY dull.

It did start up nicely, no question about that. Had a nice idle. Sounded good when I hit the gas too.

Maybe he topped off the bar oil prior to me getting there and he didn't wipe it down? I'll check the cap closely this evening and snap some pics.

thanks

Ya mean they are not supposed to leak?:bang:

I keep broken down 12 pack boxes around to sit the saws on.

Well, maybe I had just better get some cardboard to keep around for this 10-10? Not a problem.

I took a look at the oil cap and the washer on it looks good. Who knows....

Well, dang--here I thought my Husky's and Stihl's were jealous and trying to mimic my Macs..........
