Mcculloch super 10-10 automatic, chain questions

[Dieselcamino]

Well after being so sure it was 3/8th chain, the dealer was wrong it is definitely McCulloch .354. Luckily I can get my money back on the other chain, now does anyone have a clue where to source .354 chain anymore?

You will be MUCH better off buying a new 3/8 drive sprocket (about $6) than you are searching for new .354 chain.

I think that would make sense, but looking at it, it appears the sprocket and clutch are one piece, is this standard? If so A. How do I remove the clutch/sprocket and B. How do I know which length chain to get for the new sprocket?

 

[svk]

They usually take a 60 link chain. Your Dealer could shorten the one you bought.

Post a pic of your current sprocket please.

Ok, the one nut on it came right off, standard thread but the clutch sprocket assembly is pretty tight. Going to see what I have for a puller.

Thanks for the help I've never gotten this deep into a saw before

A small 3 jaw puller behind the clutch drum works well if you have one.

Odd looking bar mount for a mac, but I've never seen a RHS. Oil hole don't look right

Came right off with a few taps on the shaft. Looks like the sprocket and clutch housing are one piece, its 7 slot.

I've found unlimited clutch housings out there with interchangeable sprockets for 3/8ths .050 chain.
Sorry if these are entry level questions,
But do I need to worry about spacing the new housing on the shaft?
Can I reuse the original clutch in the new housing?
And will I need a new bar that is good for 3/8 chain?

 

[svk]

You can use the same bar.

That rim should come off that drum.

That is an "Auto Mac" clutch drum with the rim type sprocket welded to the drum.

As long as you get the correct drum for the saw with a 3/8 rim there’s nothing else to worry about.

 

[Dieselcamino]

Not 100% sure how I go about matching up the right drum for the saw. Obviously the shaft size needs to be the same, this one is dead nuts .500, that and the drum width? I would guess

 

[svk]

Any drum from a 10 series mac with removable rim should work. You could always message the seller to confirm they have the exact same one. Mac made so many similar but different saws so I could not tell you with full certainty that one size fits all.

All of the mcculloch drums/clutches I can find are spin on style where mine has a woodruff key and a right hand thread bolt.

Does anyone have any knowledge of someone out there with .354 chain? Thinking that will just be the easiest approach at this point

You only need the drum that is the same size as your current one, you can use your existing clutch

 

[Dieselcamino]

Ok, I just havent had any luck finding a McCulloch drum and sprocket in 3/8ths pitch, and if any of the ones are out there they dont list and of the sizes on it for me to confirm its the same size.

Then I also run into the issue of not knowing which length chain I will need.

 

[Dieselcamino]

Found one on amazon of all places, would it be safe to assume to find a chain that matches up with my old chain (obviously now in 3/8) since I will be using the same bar? .050 62dt
