McCulloch Chain Saws

[Eccentric]

While Kyle has been fiddling with his oiler, and oiler bypass, I picked up a PM800 powerhead off eBay that the Seller said he was selling because he was tired of fooling with the oiler. I looked the saw over real good tonight. I believe, and I'm hoping, that he just neglected to check his bar as the clutch side of the saw is covered in oil, including the lower part of the muffler. You can see where oil has burned and sooted up the lower portion of the muffler guard. You can also see where he snipped pieces out of the inner chain shield to exposed the oil port in his attempts to get oil to the bar. I also spent 20 minutes tonight with a dental pick cleaning the rails of a used 24" bar I bought - not the first one that has taken me this long to clean - so I know bars get neglected. Now that it is cleaned and dressed, I plan to run this bar on the saw. I'll know Saturday whether or not the oiler works and I'll report back with pictures if my wife's camera is available.

I hope the saw runs as good as it looks. Recoil rope has been replaced with a smaller diameter rope so I was only able to get a single pop at a time when I checked the compression. I ran out of steam when it hit 152 psi. You can hang it from the cord, but I haven't convinced myself yet that this is a reliable test of compression. This saw is one of the later ones with the DSP so actual cranking should be no problem.

I also noted that the bar adjustment nut has been replaced with what appears to be a homebuilt model that is much beefier - this is something I have been planning on making for a long time as these 82cc MACs have more grunt than the stock nut and bolt will take. You can only flatten the nut out so many times before the tip breaks rendering it useless. And you can only straighten the stock bolt so much. (HINT to Kyle: Why don't you turn your oiler bypass energies towards making some tough bar adjustment assemblies for your MAC friends? They would make great Presidents' Day gifts.) :cool2: Ron

I was in that auction early on too, but waved off. Glad you got it Ron. You're damn right about those 10-series bar adjuster setups. Just plain WIMPY, especially when used on the larger displacement saws. I HATE putting the clutch cover back onto my SP-81 with the 32" B/C. Getting that little 'tit' into the bar hole while keeping the B/C in just the 'right' place is a PITA. The large frame Mac parts are SO much beefier and give a much more possitive engagement. Heck................Mac could have put the adjuster screw assembly into the oil tank/bar pad casting instead of the clutch cover, and made the screw and nut/'tit' much more substantial. The biggest flaw in an otherwise excellent saw series. There, got my rant out of the way early......

Agreed on clutch cover mounted bar adjusters... that's one thing about the 850 that I actually don't like. Everything else I do, well except the non rebuildable auto oiler assembly...

Plus with it on the clutch cover, it's impossible to take some big washers or a fitted plate and use that to hold the bar on rather than the clutch cover for more noodle clearance. Oh wait, there's nothing else to measure clearance between with that set up...


Speaking of noodles, does anyone have a video of a 3/4" pitch chain equipped Mac making piles of them? I'm guessing those noodles would be like spaghetti compared to the little rotini that the 3/8" and .404" make...

The allen bolt ace hardware had won't work... they don't thread the bolts all the way to the shoulder. :bang: So I didn't buy any of those. They didn't have the primer bulb, nor the fuel line that I needed. I'll be off to another power equipment place after lunch.

I'll keep looking for the right bolt... as for the little adjustment tabs, I'm still trying to figure out the best way to make those...

its quite easy to run a die down those bolts that aren't threaded all the way. i've done that several times. sometimes its cheaper in the long run to own the tools to make what you want than to use fuel and time to go the store many times over the years. that's what i tell my wife when i want a new tool.:yoyo:

There's a vid me doing it with the 1-82 and 9/16 chain. I'm too lazy to find the link right now. My last appointment of the week is in 2 minutes and I'm whipped.

Now I know who outbid me at the last minute.:msp_smile: Great score.

Thanks, guys. I'm a bargain hunter and I am willing to gamble a bit. Lately, some of my gambles haven't turn out so well. I bought a DE80 from an AS member on a gamble that the parts would be worth my $ even if the piston and cylinder were shot. Well, the piston was shot after eating a few wrist pin needle bearings which is okay, but I hadn't counted on the missing paint on the tank actually being a glop of epoxy covering a hole in it. My fault for not examining the photos closer and for not asking enough questions.:bang: Maybe this purchase will make up for some of my misses. Ron

Joey, you're on the money as usual. Ron

Another HINT for Kyle: Surely by now you know I at least try to do my homework. I haven't found anyone who stocks an allen head screw with the appropriate shoulder and thread lengths. Fastenal will make me some but the quantity required to get a reasonable unit price is more than I want to pay. And the nut is the bigger problem. Ron

In that case, I'll just have to go get some of those allen bolts that I 'forgot'...

Hmm... guess I know what I gotta do now.

Ron, if you can, I could use a pic of the said custom adjustment 'tit' that you mentioned is installed on your saw...

O.K. guys, in anticipate of hitting page 895 while I am flying for the next 36+ hours, please forward these photos...

Maybe Sawbones will come along and add the action shot of that one.

Mark

Nice looking 895 Mark.
Looks very original and not tampered with.
Even has the cap in the pull handle. Often
long gone. Nice bar too but for me i would
have to have a roller on it.

[promac850]

Oh, I forgot to mention that the old trimmer that I am working on fired up today... It sounds mean with the port work and the muff mod I did on it...

I didn't seal the crankcase that well, so it's got an air leak. I'll be trying to find a gasket for it...

Why do I bring this up? Because fixing this for my buddy just might yield some saws being loaded into the back of my truck...

Lee

actually had a bunch of rollers around here but when I looked at mikes site he had a very similar hardnose in the pic.

Model Profile: 895

had it hanging on the wall for a couple years and never knew what saw it was for.

thought it looked purty on there.

 

[leeha]

Don't get me wrong Ric.
It's a great looking bar and more original.
I just have a passion for the rollers nose bars.

McCulloch PM 800 805 850 SP81

I am learning the hard way to speak eBayese. The saw several of us bid for and I "won" was titled "McCulloch PM 800 805 850 SP81". I thought this was meant to hit more search requests as we are all familar with that linking tactic. I should have taken it literally. From my inspection so far, the AF cover is the 800 part, the frame is the 805 part, the starter housing, flywheel and crank are either the 850 or SP81 parts, and the remainder could be either 800 or 805. I am kicking myself for not noticing the starter cover. Other eBay speak terms that I am learning are: "New (part)" just means new at one time/ not original to saw - it does not mean new condition; "Missing some screws" means the threads are stripped in the bosses. The language that does mean what it says is "as is" and "no returns". Ron

I have another theory on why the Seller couldn't get the oiler to work as oil leaked into the cylinder as I was adjusting the bar. Per chance he didn't replace the sealing washers on the four cylinder screws. We will see later. I am already late for my Saturday wood cutting.

That's not the way some of us that sell saws do it. Normally, people do put different numbers on their ads to attract more buyers during their search, I haven't tried that but I guess it works. When I, and most ebayers list an item as new it is supposed to be new, never used. Where some people fall down is in the "used" category. People call an item used even though it won't start or the oiler isn't working, etc. If something other than cosmetic is wrong with it, it is supposed to be "for parts or repair". I don't know how many times I've seen a saw listed as "used" and then the seller goes on to say "it starts and runs for awhile with a prime". That saw should have been in the parts or repair category. When a good seller lists a saw as "used" you can gas it up and put bar oil in it and it will be able to go and cut wood.

EXACTLY!!!!! I hate when they list it with a bunch of different model numbers, it screws up the search> Like 028s in the 026 list and 460 with the 660s..... HATE THAT!!! If I want to look at 028 then I'll type that....

You mentioned creamsickles. Creamsickles are boat anchors that are used to keep RandyMac's pirate ship parked in the bay.

Silly shop monkey. You don't park a ship, you anchor it in the bay.

Silly 8433jeff. Getting his pink pirate panties in a wad over an intentional misuse of the word 'park'...

Yeah, I know you anchor the ship/boat, not park it.

Unless you've got one of these, then I'd consider it 'parking' a boat... as no anchor is needed to keep it in place, only a mooring line attached to the dock or shore if you're really worried about your boat sliding off...

Back to Mac. GGGRRRRRRR...

I'm glad you're tackling that build rather them me..I think I wouldn't have the patience.

My Mentor

Okay guys and Mac Freaks ( You have to love yellow and black, its the law). If not, you are a ****-lite.

My chainsaw mentor actually came to me needing something. He gave me my first mac and also gave my son his first saw.
He is a older gentleman and doesn't use a computer so he asked me for help.

He has closed down his shop but still works on saws for close friends. He also puts up with my occasional visits and countless questions.

He is working on a MS1846AV and need a discontinued oil pump assembly.

part No. 9228-310208 (I believe that is it)

If any of you can help me with that I would be deeply in your debt and give you Uncle Moustaches 168th born.

Thank you in advance for any help.
