McCulloch Chain Saws

The 795 i just got has the hl19 tilly carb. It does bolt right up. The throttle linkage looks like a factory linkage. The choke is home made though. It originally had a mac flat back on it.

I officially started cutting firewood today. I cut up 2 oak logs and got 1 split before i ran out of daylight. I dont need much this year. Wr barely burnt wood last year here. It was too warm most days. Ill get what i need and be done. However i decided to get a big saw out for the sound of it!! Sp125. It started right up and ran great. What a machine that is. I had those 2 logs cut up into rounds in less than 20 minutes. They werent small either. Not giant though too. 22-24 inch diameter red oak. It was fun.

SP118 is a saw I would love to own, even if it were red and black. The exhaust tone is really cool.

Christmas came early at my house thanks to Mark..... now I have everything I need to start putting the 450 back together.

Mac 450:

How do I assemble the bottom end such that I don't destroy the PTO side crank seal? The crank has a bit of a sharp edge, (I'm experimenting with the old seal). I can work the seal on pretty easy with the crank removed but I'm a little worried about installing the seal and then just pressing the crank straight into it....

Do I install the seal into the cylinder first? Or after the crank is installed? The service manual says to use some kind of seal protector cap...do I put a wrap of electrical tape around the edge on the crank?

The last thing I want to do is tear my new seal...

good to know, I'm still in between projects, but as soon as I get time I'll be swapping the tilly over.

Use either a strip of aluminum from a beer can or thin piece of plastic from packaging. Cut it just long enough to wrap around the crank shoulder, place it in the seal and tap the seal on with a socket. Use oil. No cost method.

I like this, thank you!

Super 250 on MarketPlace.
He says he took it in trade from a collector that rebuilt it, but no pics or other docs to support that

I would like to meet/contact any McCullooch collectors in Alaska, please DM me.

Having fun....

It fought me a little....but the cylinder and bottom end is assembled.

The PTO seal really fought me....I had to install the crank into the cylinder and then install the PTO seal. When you do it this way you can work the seal onto the crank shoulder. It would not go on the crank if the seal was already installed without pulling the seal lip. I damn near ruined the seal on the first few tries but thankfully I didn't damage it before I tried the method that worked.

One of your pictures showed the crank installed seemingly. I didn't think to mention that should be done first. Now you know. The flywheel side crank is generally tapered so the seal being installed first isn't a big deal. If you ever work on a Canadien or older Pioneer you'll find the seal behind a lip in the cover. Means the bearing has to come out and the seal installed first from the back.

Yeah I was following the service manual that said to install the PTO seal first, found out that wasn't the way to do it!

They probably had the special seal tools to protect the lip.

Yep exactly.... live and learn.

Question on reassembly... am I better off installing the reed block and airbox next? Or the fuel / oil tank assembly? It's like a puzzle...
