Here is one of the lesser known McCulloch saws, the 440. I already had/have 3 of the 450's, only one of which is a runner right now, but BigBore77 found this one for me a long while back.

I was able to go by his place last August and pick it up, and finally got around to getting it cleaned up and going. The morning I stopped by he was called away on an emergency but his wife was gracious enough to pass the saw along. I only got to see a couple of his saws and his truck parked in the garage. She said he had the workshop locked and took the keys with him, smart man.

Here is the saw in the front of my pick up, back of the truck was completely full and it was starting to rain.

I'll add some more photo's and details later.

For now...

I like it but, I'm biased. Please show more when you can. I think it's a beauty!
 
Some guys lock up their wives, some guys lock up the booze, other guys lock up their drugs. I'm glad to hear Jay has his priorities in the right order. :)

Mark- that's a good looking old Mac. I'd be real interested to see what all that writing is engraved into the air filter cover. Looks to be some historical information.
 
A lot of the saws I get have some history, this one is just has a bit better documentation.

For Mrs. McGinn, here is a photo of the saw on top of the dishwasher. This one happens to be a portable that I can wheel over to the door of the bathroom (in the background) and connect to the faucet when I have a "load" to do.

I did a bit more tinkering with the saw last night, adjusting the carburetor and such, seems to run and respond pretty well now. Not as snappy as the SP125, but still has a nice thump to the exhaust.

This saw was in pretty good shape when I got it, so I was hoping for just a simple clean up and away we go...unfortunately the manual oiler would not spring back so I had to go in further than I had anticipated.

Good news was everything came apart easy enough, and after a gentle honing with some emery cloth on a shaft in the drill, the oiler piston was free to move again.

Here is the saw with the oil tank separated from the front of the engine, the oiler piston and spring are removed. Note: a judicious use of compressed air in the oiler discharge hole combined with a rag over the oiler bore sucessfully extracted the stuck plunger.

Here you can see the piston and spring in the oiler bore, and the pick up tube with the weight/screen at the bottom. The barb where the oiler attaches is also the check valve for the inlet side and these frequently get stuck when a saw sets around for say 10 or 20 years.

The oiler discharge hole is the large one in the center of the photo. You can also see the pipe plug about 1:00 from the oiler hole, that give you access to the top end of the check valve/oil tube if needed. Gary if you read this, you might try removing the plug and applying some WD 40 or something similar down the hole to free up the inlet check valve.

Here are almost all of the parts for the pulse operated oil pump.

It seemed to me something was lacking so I looked at the IPL and sure enough I'd lost a spring somewhere. A careful search of the workbench proved fruitful.

This story will be continued...

The automatic oil pump is operated by crank case pulse pressure, here you can see the pulse passageway in the bottom of the "stuffer" or crank case bottom cover, the hole in the center mates with the cast in "tube" in the photo of the inside of the oil tank above.

At this point I thought I had it whipped, but it would not oil no matter what I did. The check valve in the pick up tube was working fine, but I had no way to test the check valve on the discharge side, that little ball and spring in the photo in the previous post. I decided to try something else, so I took the discharge check valve from a 200 donor saw and put it in the outlet hole. This should not be required on a saw with an automatic oiler, but is the standard equipment on saws with manual oiler only like the D44.

Here is the 200 oil tank to the right, the 440 to the left.

The discharge side check valve for manual operation.

The ball and spring in place...

...and the check valve is now complete.

Oh, by the way, the oil tank on the front of this saw with the automatic oiler is the same one used on the 740/790/795/797 and the SP105 and SP125 saws and probably others I haven't thought of. Without the automatic oiler it goes back into the D44, S44, and S44A models, 1-70, 1-71, and others. You get the idea, McCulloch designed in a lot of intechangability and kept with it for over 30 years in many instances.

Here are a few shots of the finished product:

I am sure I mentioned this already but I think it is worth repeating. This saw has the McCulloch "flat back" carburetor by Walbro and I used a kit from Joe Salva at Sugar Creek Supply. Parts fit well, work well, and Joe's prices are very good. You can find him over at CSC.se or search on Sugar Creek Supply. He also has a lot of repro decals as well as other carburetor kits including the Carter ND found on the Wright saws.

Ray - If only you had a brother that could help you with questions like that...

Look for a setting on the camera that looks like a flower and turn it on, that is the close up mode.

How's life now that you don't have to go to a regular job everyday?

For those of you that don't know him yet, Ray is my older brother (recently retired) that I will now have to continue working to support.

If he's Mark's bro, he has got to be a good guy. Somebody give Ray some rep! It won't let me.

Maybe he'll let us see a few more pics of that NOS MAC 35 he has in the original box.
