Never heard of one? What can you Mac yellow bloods tell me about them.
-
I've never seen one but I assume it's a variation of the 10 series .3.5 cu inch or 57 cc .According to Mike Acres site they were only made for two years ,late 70s' .
Without looking it up and if memory serves the very last of the 10-10's were the same displacement .
McCulloch being McCulloch would periodically just change the model numbers on essentually the same model of saw from time to time as they saw fit .

Dang made in 77 78 Mac 555 http://www.acresinternet.com/cscc.nsf/ed1d619968136da688256af40002b8f7/e6e4236d1011d83288256c2f001c5314?OpenDocument

The mac 555 in my pics above could have been bought for $75. Just wasnt worth the hour drive there and hour back to me.

It would have definately been worth 75 bucks to someone that needed an inexpensive firewood cutter .
I still on occasion get out a few of my ten series just to keep them exercised .They'll still get-er-done in grand style .A day here a day there but I wouldn't care to every day while I have better saws to use .

I have a lead on a Pro Mac 555 with a bow on it. The guy wants $125 for it. (It's not advertised). I haven't seen the saw or any pics but he says he's been using it so it apparently runs. Is this something that I should run down to flip or is it going to be worth less than I have in it? It's probably an hour drive but I will be heading that direction for another purpose most likely and maybe could combine trips.
I saw a reference in this thread that it may not be much more than a Mac 10-10A. I just sold a 10-10A for $60 in good running condition, so if it is the same thing, I'll just let it set. Those old saws don't have much market appeal around here. If it doesn't say Stihl on it, they're pretty hard to market. I sell rear handle plastic Poulans for $50, top handle Poulans for $45, etc.
I don't collect saws. I have ones I use and anything else I get is just passing through. I play with them a bit and then sell them and try something else.

It's a $50-$100 saw by itself (unless you get lucky selling on ebay). The bow is also $50-$100 on feebay. Not much meat on the bone for you. Good firewood saw.

Just had a nice looking but not running right now, mac 555 come in today.
Weird part coming off top handle into center cylinder cover it seems. Looks like part of handle to me . Will grab some pics later.
-
Soon as I bent down to pick up to set on bench I seen what was going on :D :D with the strange deal going to top handle. Redneck gas cap. ;D
-
Got them both running the plastic mac cat in background needs carb kit, af and other choke linkage parts. The 555 needs a gas cap and idle screw so far. But did get it running.
So what other model gas cap and idle screw work on the mac 555?

Least now I know what the idle screw looks like. Found a pic on Chainsaw Collectors Site.
-
I was going to make the idle screw from a allscrew or bolt, but couldnt come up with the right threads in my barn stash.
-
Probabley a 10-10 for both.I might have something in the shed but it will be a couple of days before I can look .
-
Thanks for checking Al. Waiting on owner to call back on both saws to see.
-
If you get the thing I have both the fuel cap and the screw .Let me know and I'll send them through the mail .

Thanks.

Talking to original owner that bought this saw new. He said it had original b+c on it. Went out and confirmed mcculloch 370 labeled chain.
Al the 555 was traded into me.

There were several different 10-series fuel caps. They are all interchangeable between saws in the series. They can all have the duckbill valve replaced with varying degrees of ease/difficulty depending on the particular cap design. Homelite 69451 valve (still available from Stens and Oregon) will work with a little reaming of the hole it seats in.
Idle speed screw from any non-AV 10-series with an external idle speed adjustment (some had the adjustment at the carb) will work. The later non-AV 10-series saws (Pro 10-10, PM10-10, PM10-10S, 7-10A, PM700, PM55, PM555, etc) all shared just about all chassis parts. Their differences lie in badging and sometimes internal engine parts (pistons/cylinders) and carbs.
The PM55 and PM555 were later 57cc 10-series saws with a comp release. They share most (but not all) parts with a PM10-10S (which is also 57cc). The 'S' model has a different cylinder with more aggressive porting. No 'straight' 10-10 (PM10-10, Pro 10-10, 10-10A, etc) were 57cc. They were all 54cc without a comp release.

Thank You Al, received the cap and idle screw today.
Good news. Idles like a charm now. Manual oiler only? Works great though.
Bad news was from my Doc today and the saw was ringing my ears when blipping it :o. Guess missing a diffuser type deal I remember being on the 805. So at least something good today.
Pics uploading will update when done.

Being I'm not a mac person. Al you got any of those poulans etc I like to trade for?

Heiman a Mac collector said the the 555 is basically the Pro Mac 55 with long clutch cover. http://www.acresinternet.com/cscc.nsf/ed1d619968136da688256af40002b8f7/6d84f07aeb6a1de288256c2e0075c542?OpenDocument
Says 16" to 28" bar for 57cc saw. :o
Was looking for the bar mount. D276 ? http://www.acresinternet.com/cscc.nsf/BMP/11?OpenDocument
-
FWIW some Husqvarna bar mounts will work on the 10 series Macs . For that size displacement I'd say a 20" would be about right ,which is what I have on a Pro Mac 10-10 S which is the same displacement .
Now the saw.It has plenty of power for firewood cutting .However the difference between its' 57 cc and 70 cc of the 700 model is very noticeable .
-
D176 is the current mount for these saws. Fits midsize Echos and Poulans as well as the 10-series Macs.
A large mount Husky bar will fit on these saws, but I'd be very skeptical about it oiling right, at least without modification. The 10-series saws oil through the adjuster holes on D276 and D176 mount bars. If trying a D009 or D005 type bar, be SURE to check to see if the oil passage on the bar pad of the saw matches up with the oiler hole on the bar. Modification may well be necessary...
Kevin that muffler is missing a loovered outlet cover. Looking in the IPL you can see that there were three muffler types used on that saw. The one that's on there is by far the loudest of the three. That muffler is most often seen on the earlier 54cc 10-10A's and such. They are indeed LOUD. Both the 'reed type' flat muffler and the 'L shaped' muffler also shown in the IPL are quieter. Most of the 70cc saws have the 'L' shaped muffler. The muffler that was on your 805 is a much larger, more complex type with a large spark screen tower. Those were only used on the later 82cc saws.

The 28" b/c's were mostly put on those smaller 10-series saws for brush and 'bumping knots'. The 54 and 57cc saws in the series will run a 20" bar very well, even in hardwoods. The 70cc saws are much stronger (as Al said) and can run a 24" bar in hardwoods no problem (and can run a 28" if you're not too heavy handed with them). The 82cc 10-series saws are in another league...
-
Great info and Thanks Aaron. I was hoping a longer D176 would work if someone wanted to try it with one. Right now just the original 16"
Again Thanks Al without you sending me parts when you did this wouldnt have been possible to check over. Thank You. 8)

Al is awesome. The ultimate "make things WORK" guy. Not many 'old school' machinist/problem solvers like Al left anymore. Cylinder in his old Mac roached? No problem. He'll resleeve it. I wish I lived closer to you fellows.
-
I'm not certain of what they are called but Mac made the mufflers with a sweep type bend for both the 70 and below as well the 82 cc ten series .To me they are the best for performance but they are also ear drum breakers .
They are so loud you need muffs because plugs won't get it done .
I have a sweep muffler on the 805/850 and it has no problem handling a 32" in oak buried ,skip chain .
I'd say with confidence the old gal could pull a 36".
