McCulloch Chain Saws

[heimannm]

Thick rings = 0.062" or there abouts, the ones I just checked with my dial indicator seemed to be 0.063+

Thin rings - 0.025".

While I was up there looking I found two sets of 48691, thin rings for the 2.125" bore saws like the 1-81, 1-45, 1-72, 1-75 and several of the kart engines.

I just had a scare!! Thought I ran out of beer for a second. Wife must have moved them on me LOL.

I understand that the thin vs thick ring thing, especially with the 80/87cc macs. Are the thick or thin rings .062"? I don't have any Mac rings outside of the saws to measure at the moment. The 1-76/86 saws are listed with both types of rings in the 1962 McCulloch Pistons/Cylinders?Rings parts list.

Just ran out to the shop and checked the 1-76 rings with the micrometer, looks like about .025 with crappy light and no glasses - Sam

If your talk thickness, then
you have the thin rings.

Sam - If you have a spare set of 1-76 rings for sale we need to talk. I have a relatively nice 1-76 with about 130 PSI compression that could use a little freshening up.

Mark, the rings in question are off of a saw with a scored piston and fairly pathetic compression - I am looking for new rings as well. They do seem to be out there though, just a matter of money as always - Sam

 

[sawbones]

Thanks Sawbones, I counted links and came up with 10.5 per foot. No number stamped on them, but what appears to be the brand name was stamped, BW in a little square....anyone know who made this chain?

Thanks - Sam

sounds like you have a 9/16

BW is Borg Warner-Atkins chain.

You guys don't need to spend big bucks on rings. You can get rings made on the cheap at Otto Engine Works- Home

Thanks for that reminder JJ, I've added it to my favorites this time so maybe I will remember to check with them when I have some time.

Got a G-70 that has a 1/2 pitch chain and want to switch it to .404. Anybody have a spare sprocket or know where to get one?

Thanks,

Thanks,

I lucked out, have an adapter.

I lucked out, have an adapter.

Where did you get that? Got another one? And since I've got you, do you know if any of the others from another model will fit?

Thanks Randy!

 

[RandyMac]

Sorry Randy, only the one, it will be transfered to a 2-10G to run a 28" bar with 3/8" sawchain. I got that one from Ric, who didn't quite catch me before I hauled the saw off.

 

[watsonr]

So now we know where you got it, anything out there that will work...maybe from another saw? Or am I stuck with 1/2 chain.

Were you laughing as you were running?

 

[RandyMac]

No, but I had a chuckle later. I'm not sure how strong it is, I wouldn't put it on a 660 or 895.

 

[watsonr]

it looks like a rim sprocket on an adapter, now that is quite different. I don't know how tough it would be either, for a lower cc saw probably wont be a problem.

Looking at the IPL it lists one for .404 as an option, somebody has to have one or know where to get one....they did make it....right?

What other saw does it swap parts with easily?

Thanks Randy,

Randy


I'm talking to myself' now, what's next...

 

[RandyMac]

I don't know Randy.

Thanks Randy!

What's the output shaft diameter?

1/2" Chain + 1/4" file= Sharp chain, now get to work!!!! :msp_wink:

But really, you don't have a monster HP saw, no speed demon. So unless the 1/2" chain is shot, why don't you just use it??

BillG said the Mac shafts were all the same, I don't know.
You givin' away .404 sprockets?
The 1-60 series were often .404.
