As per above post- May I ask what is the symptom of a worn out sprocket? Because my chain is difficult to tighten, seems to increasingly get tight as I run it. Cheers.

An Oregon D176 mount bar would be a cheap alternative to the bar your running, the power match has a greaseable tip.
If it is genuinely a D-45 it is a pretty rare saw, though not all that sought after. I think there were only few made and they were all made and sold in Canada if I understand correctly.

Do you pull the tip of the bar up when you adjust the tension?
I believe it is a genuine D-45,it looks identical to yours Mark.

I received my SP80 decal today so I finished up the cold weather saw for display.

I do, but maybe not consistently enough. I'm not sure. But as is the case I thought I better remove the clutch assembly and replace the spline. I had a new one on hand, they are both 3/8-7 (see photo). But the new one doesn't fit - diameter is too large. Shucks, that's the issue with buying stuff online I guess. Will head over to a brick-and-mortar shop to see if they have what I'm looking for. In addition though, what is the size I am running on this saw and what are some good standard splines I need to look for that fit the 10-series? Thanks in advance!

Yeah,it doesn't look like I'm getting that D-45.I countered with a $135 offer & the seller thinks it's made of gold or something similar & won't take less than $175.I'll let her sit on it for a couple of months & see if she'll change her mind.
There are three standard 7 spline sizes commonly used today. Stihl uses a "Mini" on some of their smaller saws up to and including the 036 size saws. I don't know the dimensions of those off hand.
The standard "Small" spline is 3/4" I.D. which is also referred to as 19 mm.
The standard "Large" spline is 7/8" I.D..
There were drums that fit the 10 Series saws in both Small and Large spline so you need to know which you have in order to get the correct sprockets.
And one additional twist. There was a peculiar clutch and drum that was supplied on a few of the early SP80 saws. If you have a new drum in a package it will clearly say something like "SP80 only" or "All 10 Series except SP80". The clutch is easy to recognize since it has three shoes. The drum is harder to distinguish but it is slightly smaller in diameter.

Thank you Supervisor and Heimann. Heimann - are you having or supplying a chainsaw museum? I just find the stuff you're sharing here absolutely amazing, but I'm, sure you hear that often. The walking encyclopedia for Mcculloch!
MS - I think you are right, mine must be 19mm "small" size. Why I'm saying that is because I the other spline I got was too large, so deducting from what Heimann explains, mine should be the 19mm. Theoretically it could also be the mini, but I just doubt that.
I'm also attaching a couple of pictures showing that the drum doesn't say anything specific, except for Made in Canada, McCulloch, and then GY, and the number 86948. Clutch is standard for the 10-series then.
Thanks much,
Simon
PS: Just now (Saturday morning, Japan time), I went to a brick-and-mortar store that sells power tools including power saws etc., this is a labourer store and not a home center. Surprisingly they do NOT sell splines, but the guy knew what it was instantly. So weird...I bet they have them out back but prefer people come with their saws to get them serviced rather than buying a spline and doing it yourself! I am all for supporting the local economy, but I want to do this myself.

I do have a museum and I am working on adding saws as I get them cleaned up .

Look at the photo of the SP80 drum inside the other drum above and notice how much thicker the spline is compared to the one in your hand; the SP80 drum is equipped with a large spline.

I'd mail you one , but it would probably be alot quicker to find one locally or online.
I have converted a few of my 10 series saws to the newer Oregon rim drum that is large spline but have a couple saws that I just can't bring myself to change because they're like new.

On a side note - found this gas cap in the store, price tag all weathered and yellow, had been hanging in the store for many years.
It fits the McCulloch perfectly. I know it's not original but hey, now no leak from that end anymore at least.

You know when you get it, it will be in nine pieces, just sayin.
Thats a great find , strange but I'd be excited about the cap.
No Joe,the seller is so dumb she doesn't even know where or what the muffler looks like,so the bar & chain stay on & the packaging is done around it (true).

Yes, me too especially when my hunch was confirmed that the cap fits! And for sure this particular spare part that had hung around in the tool shop for a couple of decades, the plastic packing was crumbling and all.
Meanwhile I found out a bit more on this gasiline cap: It is for a Japanese Shingu chainsaw (SP531). There are a few second hand caps like this for sale over here but seems even that isn't produced anymore. Incidentally (and this is just as much a tidbit of trivia for @heimannm to add to all the stuff he already knows, and @SEAM told me) - Shingu was also the distributor of McCulloch in Japan, so likely they copied a few things from the Macs back then, including gas cap design. Cheers!
Make sure the saw oils in milling posture (on its side). Pickup lines tend to harden over time and the oil filter may not be able to follow the oil (gravity) when the saw is on its side.
