McCulloch Chain Saws

[Syncop8r]

You'd better get the standards groups together and have them decide on who's metric system you are going to adopt as there are at least three out there...with different thread pitches (at least three different pitches used on M10 fasterners for example) and the hex sizes accompanying different size fasteners. M8 fasteners might have 13mm, 14mm, or 15mm across the flats, M10 fasteners can be 14, 15, 16, or 17 mm depending on where they are made and who's is specifying. And nuts frequently have a different measurement across the flats than the screws that go with them. Not really a universal system.

Whereas Imperial only has:

Unified Coarse Thread
Unified Fine Thread
Unified Extra Fine Thread
Unified Miniature Thread

British Association Standard Thread
British Standard Fine Thread
British Standard Whitworth Thread
British Standard Pipe Thread
British Standard Taper Pipe Thread

And a few more....

Cleaned up pretty darn good.

There are 3 or 4 more 10-24 screw through the PTO side of the housing that actually hold the engine in place, then you have to either remove the bar adjust screw, or pry the housing over it as you push the engine out. Those screws can be hard to see as they are deep in holes and often buried in oily sawdust.

the bar adj screw was the stopper. Didn’t try prying it. Thanks

It's alive.

How much vibration is normal for an AV 70? Really seems to buzz compared to the 81.

Come out rather pretty I think
Now to choose a bar from the pile

I've got a couple of these nos bars but hmmm the yellow isn't quite right

 

[vinnywv]

Looks great. Well done.

I would have to say the SP70 saws that I have run were actually quite smooth. The PM8200's...that's another story.

I do like the look of those 20" bars you have, can't say that I have ever seen an equivalent over here.

Must be that three piece crankshaft. Ron

 

[PogoInTheWoods]

Or the excessive sealant that gets all over the piston and smears up the cylinder.

 

[heimannm]

I sent one crankshaft up to Treemonkey to have it checked thinking that was the problem, he said not.

Cheers. See what she cuts like.

I just seems like something is not balanced well or perhaps I've been spoiled with the 266 lately as that's all I've been running.

I'll get a bar n chain on it n see how it goes.

Yes those bars are nice and were a good score at 45nz I had 3 but sold 1 on that 700. I new I should have grabbed more. When I go to work I'll post a picture of the packaging. They are a odd 10mm slot. Probably fit a large frame easy

Hey we all appreciate a good saw. My 266 is my go to saw. The 162 also and a very important saw in history as kinda changed the game and could say in many ways most modern saws are in a way built off that design. Everyone had a go at it (except Mac) "610" excluded but the basic tank and handle together produced a nice lightweight saw and many companies were left with their pants down for a while.

Kinda feel the 2 series huskies are a wonderful mix of old and new.

Cool thing is the 81 still hangs with my mates 181 with a 288 top end. Unfortunately the power to weight of the 81 was gone by the time the 181 came along

Bet that ported 266 of yours is a weapon

 

[Jethro 2t sniffer]

As promised
