MCCULLOCH The official McCulloch thread

Bigger trick is finding the right rim drive/bearing setup to run 3/8's if converting from a .404 spur. (depending on crank diameter.)

Yeah.
Different bearing. Can I get a number? Bearing doesn't come with rim drive clutch cover kit.

The 5.3 cubic inch,87 cc engine is my favorite of all the big McCulloch reed valve engines .That one they got right .
There is a trick however on the 80 cc units like a 250 .If you can find a .050 groove bar and run 3/8" chisel with an 8 tooth it will cut a lot faster than with .404 .Surprising with that set up it takes 72 drivers on a NOS 18" Mac bar .I chanced upon one still in the cardboard wrapper . NOS Oregon probably 50 years old .

Be nice to use this.

Was wondering if you ever found a solution for yours.

Wow what size bar you got there?

Don't want to reinvent the wheel just want the Mac part #.

Remington branded Windsor.050 38" roller. Dad bought it for a SL-55 that I still have. Circa about 1972.

Super 250? How does it pull that long of a bar?

Haven't found out yet. Hence the needed bearing.

Pick one...

You're on your own for the right bushing..., which is probably why you haven't found a bearing solution yet. Measure the crank. Look at realistic bearing options that'll work with the drum and then use a bushing for the difference.

More like math than geometry.

That is a nice bar, btw.

Oh I see. I have a couple part saws. I'd gladly send you a used bearing

You're welcome.

Pogo, Where can I find that sheet. Nice info.

It's Oregon 10608 . It has a bushing but I suppose you could knock it out and put in a bearing but it wouldn't make any difference on how it works .No picture the camera battery went dead because some dummy forgot to charge it ,guilty as charged .

While on the subject I had adapted a standard Stihl mount 32" bar which I ran on that same 250 I have the .050 bar on .It pulled it no problem . That bar now is on a souped Stihl 038 Mag .--and it pulls it no problem .

Close up Pics of of that bar Please.

I've got a Plenty of Squeal Bars.

Which one,the Oregon 18" hard nose or the Stihl? The Stihl is just a standard anything from an 024 to 066 size .All it takes is spacers,kind of like thick washers from the 3/8" bar studs to whatever the bar slot is ,12.4 mm maybe .< I forgot .You have to adapt the oil hole and the the bar tightening hole but that's no problem with a die grinder .FWIW I've put Stihl bars on a lot of saws for the simple reason they are easy to find .Try and find for example a 36" Homelite bar in decent shape for a Homey 2100 S .Nearly impossible,Stihl yes,Homelite no .

On the above give me a couple of days .The next three days are 12 hours and I'm trying to change the rear tires on my Ferguson which was brand new in 1951 and wore the tires out .I was brand new in 1948 and I have a lot of life left .

That 10608 Oregon drum comes back to Montgomery Ward saws "and some larger McCulloch models". No needle cage,of course.
May actually be the ticket but doesn't turn up in a Mac search. Here's what you'll find otherwise...
