MCCULLOCH The official McCulloch thread

[Al Smith]

I manage to fall into stuff and as such have only paid for one 10-10 Mac .That one came in a pile of McCulloch stuff I paid more for the shipping than the parts .The only reason I even bothered is because the collection had a bow bar similar to one I used on a 250 when I was a teenager .BTW that event the 250 was brand new at the time . I have the bow just never used it .The 250 especially for a 250 super is not a bad saw at all .A little heavier and slower than a modern saw but unless you straight gas them will run almost forever .If you want them faster change the .404 chain size to 3/8" chisel with an 8 pin rim.Then observe the looks on peoples faces as the chips fly .

I think the 440 is a little faster cutting than a 250. Your lucky you can find mcculloch stuff for free! Were I am mcculloch saws don't even exist. I have to buy them on ebay.

I'll have to look into to adding the 8-tooth 3/8 to my 250. Pretty sure that there is a fresh 10 pack of them in parts box somewhere.

Hey everyone, new here. First question for me.

With the recent events of Hurricane Helene, my grandfather's Pro 10-10 Automatic was brought out of it's icy crypt to wreak havoc on fallen trees and limbs. Says he purchased it from JCPenney sometime around '77. It currently has an 18" bar.

I am looking to get a 20" bar, but have hit a roadblock. Some online say I will have to change the current 3/8 sprocket to a .325, and some say I don't have to. Thoughts?

Hello and welcome to the forums! I am currently working on two 10-10s (early 70's) units, can't wait to get them running. You should be able to find 20" bars that run 3/8" chain. I believe from what I have read, people have put on 24s and 28s, but not sure if their saws were ported or not. I don't think they should have any issue running a 20" 3/8" bar. Might have to search the Oregon catalog to find one. You will need to verify, but the 200VXLHD176 might be what you are looking for (20", 3/8", .050")

Found the 200VXLHD176 on Amazon for a decent price. I've worked around Oregon bars/chains for several years (granted I'm only 21), so not a bad deal at all. Thanks for the information!

Any 20 inch 3/8 oregon bar with the smaller bar stud size will work. I run 28 inch bars on my 10-10s with 3/8 chain and they will buck 30 inch hard wood no problem with .30 to .35 rakers.

Good to know, are those saws stock or ported?

Down here now a lot of wood laying everywhere. A lot of places still boarded up.

Absolutely, some places here in the upstate SC area are still cleaning up. Our Stihl MS 251, Echo CS-310 (“the little chainsaw that could”), and 10-10A have been putting in work. Countless chains ruined and replaced.

I found the problem with the SP125 rercoil - one of the pawls was stuck in an inoperpable position on the FW & the recoil was missing 2 screws that hold it onto the fan housing.Hopefully it's good to go now.

Unless your 18" bar is shot, I would be inclined to continue to use an 18" bar & chain on a 10-10, after all they are only 54 cc.

The 10-10S is 57 cc but has more aggressive porting and would handle a 20" bar much better.

I like to run 16" on the 54 cc saws, 16 or 18 on the 57 and 60 cc saws, 20 or 24 on 70 cc saws, and 24 or 28 on the 82 cc saws. If I need more than 28" I'll select a bigger saw...



FWIW, the 10 Series direct drive saws all use the D176 bar mount and there is no reason to run .325 chain on any of the 10 Series saw. They have more than enough torque to pull the 3/8 chain and don't really have the chain speed to really take advantage of the smaller cutters on the .325.

Here are some photos of my Pro 10-10 Automatic that I mentioned earlier.

Of all the 14 or so 10-10 model variations, I like the Pro 10-10A the best.

The 10-10S was the last 10 series made wasn't it?

 

[heimannm]

10-10S was the last 10-10 version they released.

I suppose the PM4300 and PM8200 were the last of the 10 Series chassis saws made.

Nice looking saw! A 28 inch bar is my favorite on a 10-10 because you don't have to bend over when cutting up small wood. Its a real life saver when cutting 10+ cord of wood as I do with my 10 series mac saws.
