The unofficial Mac 10-10 thread

[PogoInTheWoods]

So according to Mike acres site a pm 55 has a chrome bore and a 10-10s has an iron bore.

Tim's post explains what I was referring to regarding the possible concern with differing materials between the rings and cylinder. And while the Acres site provides a ton of valuable material, I believe I'd trust a magnet over what's provided there -- especially in the case of McCulloch info simply due to so many mix and match changes on any given production run of any given McCulloch saw.

Thanks fellas. I'll try a magnet this evening. I know my rings aren't chrome for sure

Took SOME effort to get the insert out but a few people (Poge) were asking about this type fuel cap.
The only thing you can't see is the beehive spring in the bottom. I left out the plastic bit and used the taller poulan valve.
Thats a rock or hardy board screw.

Right on. I recently picked up a saw with that cap and was brainstorming how to fix it. I was just going to drill it out and make my own insert for the duckbill. Do you have a part number for the poolan valve?

Aaahhh? The green one on Amazon. Sorry thats pretty much the extent of my knowledge.

Fyi I used a huge flat blade screwdriver to just catch the edge of the tube where the insert fits , took about 3 tries.

Cool thanks!

530026119 for the duckbill

So that's one of the caps that appear to not be serviceable? Looks like one helluva press fit if it took that much leverage to pop it apart. And you just pressed it back together with the spring and a new duckbill?

The green duckbills come by a few part numbers depending on source with the 530026119 being a pretty common one. Homelite and Stens have their versions as well. Then there's the shorter pink Homelite 69451 (Stens 610-345) that you can find everywhere also.

Yes just pressed back together with spring and.... an oring around the neck of the duck bill valve, because the hole is fairly large and I wanted to stabilize the valve but not squeeze it. I think thats what the plastic part was originally meant for, it was full of black jelly.
This is the cap type that I broke last year trying to remove it normally by grasping the stem with pliers and twisting. The whole thing looks like a hex head bolt when freed from the cap.

I know I've got another one of these in my saws , Tomorrow if I get some shed time I'll make a video of the process I used to get it apart, after all shouldn't success once breed over confidence! Lol

I recently did one of the aluminum ones. Not near as well as Maintenance Supervisor. I drilled the insert out and inserted a vinyl tube with a duck bill inside. Works fine.

I got a little spooked trying to pull the insert in case I shattered the cap.

 

[PogoInTheWoods]

Ya musta misspelled duckbill, eh?

 

[fossil]

fixed

Yep. It wasn't an F but rather an i.

Kind of like **** Cheney.
My, aren't us AS guys politically correct?

 

[Maintenance supervisor]

Whelp, over confidence did indeed spell disaster today, shattered the fuel cap for the ProMac 60 so no video of me swearing.
Maybe it was just dumb luck that the first one I tried worked but with no market for reasonably priced caps I'm gonna stop while I'm even , 1= fixed 1= broken.

If you ever get desperate the later Homelite Super XL / EZ etc. caps work just great. The one in the pic is missing the sintered plug and Homelite duckbill.

Sorry if this is posted in the incorrect location, please advise if it is.

I recently cracked my brake case cover. Between the two bolts. My bar will not hold in place now. My 10-10 is fun to use, but I'm not sure it is worth hunting down a replacement part.

Any thoughts? Should I invest in a part for a saw that is my backup - and "fun saw"? Or should I retire this chopper sounding cutting machine?

What would you do?

 

[PogoInTheWoods]

I'd fix it, but that's just me. Should be able to find what you need if you're patient and keep your eyes open. May even be able to find a complete parts saw cheap enough to buy just for the sprocket cover.

 

[Goinwheelin]

There is enough of those 10 series out there you should be able to source another cover, or repair the existing one. If all else fails box it up and send it to me, I’ll gladly take it off your hands

Scrap yard is a popular place to start. I fixed mine with epoxy and steel stock shim.
