McCulloch Chain Saws

[leeha]

The intake boot on my sp125 I'm trying to get going has a split in it. does anybody know where I might be able to find one of these? I believe it is part #69889.

Thanks,
Jeff

Jeff, That intake boot has been discontinued for
quite some time now. A hard part to find these days.
There are no aftermarket ones available yet. I believe
it was thomas72 that adapted a Stihl 084 boot with
success. Originals do pop up on ebay every now and
then but not often.

I recently took apart an SP125 that had the modified Stihl boot in it. I have the Stihl part number written down somewhere but not with me today. I believe thomas72 said he made one from an 084 part.

Here is a photo of the cut down Stihl boot. This will not be a high performance retrofit as the Stihl part is much more restricted than the original McCulloch.

Try Saw King for a boot, he frequently has good used ones. I think Stinkbait found some a while back as well.

On a related matter, if you had a few old McCulloch rubber parts on hand (boots, fuel lines, duck bill valves, etc.) what is the best way to store them to make sure they are preserved? Armorall? Air tight bags? In the freezer?

Mark, I haven't done it yet nor do I know if it is worth the effort, but based on my limited understanding of dry rot and rubber tires I am planning on fitting a paint can lid with a tire valve; putting the rubber parts inside the paint can; purging the can with nitrogen (from a tire dealer or auto dealership); replacing the lid tight; pressurizing it with nitrogen; and storing the can right side up. As with all my projects, I have less time than my imagination allows. I have yet to make the can and experiment with how much pressure it will hold before the lid blows off or leaks. I believe the absence of oxygen and the presence of pressure work together to slow oxidation and keep the "plasticizers" in the rubber. Ron

How about a slight local modification to the plan?

... like using one of these instgead of a paint can?

Mark,
Thanks for the picture. If you come across the part #, I'd like to get it. I'm kind of new here, who is saw king? Is he a member here, and if not, how can I contact him?

Thanks,
Jeff

that might work.

Another thought would be to clean the items of any oil or grease since the petroleum will disolve the rubber. Then, coat liberally with silicone (one with no petroleum solvents, perhaps the amsoil brand spray; or a non-cleanser silicone dielectric grease). chuck the cleaned and coated items in a ziplock bag. suck the air out with a straw. put ziplock into some light-proof container; a paper sandwich bag would do nicely. Label container appropriately. Last, store the parts in a climate controlled area - not in a hot garage. That'll do.

coating and ziplock stop the oxygen and ozone. paper bag stops the UV light. temperature stops the, um, high temperatures.

 

[heimannm]

Thanks for the suggestions guys, I keep thinking I should move those kind of items from the cabinets over the part washer...

Jeff - Saw King is a long time e-Bay seller, I don't think he posts here. You shouldn't have any trouble finding him via e-Bay or You Tube (chainsaw guy) as he does post a lot of videos on his stuff.

I agree with you on the engine swapping crap... it sickens me... like an LS1 into a nice 1994 Mazda RX-7... they hack up the engine bay and mess up the wiring to put that v8 in... Or putting a SBC into a Ford Mustang (did anyone ever do that anyways?) Or taking a nice IH engine out an putting something else in that doesn't ever belong in the engine bay of a different name vehicle...

About the only swaps I am okay with are ones within the same brand name (I.E. Nissan Skyline GT-R RB26 DETT into an old Nissan Maxima wagon like mine, or a 632 cubic inch World Merlin Chevy V8 into the Suburban...) Exceptions would be the old VW Beetles... I think it'd be pretty damn cool to have one with a SBC or a turbocharged RX-7 engine in it...

Got some troublemaking stories about that Travelall you are talking about? Me wants to hear them.

I dunno, I have seen some turbo bowtie powerd fox bodys that will put the fear of god in ya

Maybe, but I would worry about that 52 year old seal.

Dang!, It's just a chainsaw!

True, but some of these obsolete molded rubber parts are critical if you want the saw to be runable 20 years from now. For my saws, I am thinking primarily intake boots and av mounts as I believe I can easily rig replacement fuel and impulse lines.

It's improper.

I do not like how people hack the cars up to put the wrong engine in. It's like taking Eccentric's cool little Scout and dropping a Honda Ridgeline engine in. It's wrong on so many levels. Unacceptable.

A Ford T-Bucket should never have a SBC or BBC, only SBF or BBF or better yet, a Flathead V8... improper engines in a certain car/truck is stupid as it pretty much always requires major hacking to get it to work.

A Chevrolet Camaro should NEVER EVER have a Ford engine, or anything else than a Bowtie engine for that matter.

A Dodge Ram 2500 should never see its Cummins 12 valve torn out and a 6.5 GM diesel shoved in...

Ever see that video on youtube of a formerly pristine and mint Honda CR-X totally destroyed and hacked up so some stupid ass that thought it'd be "cool" to put a BBC in it, and make it RWD? Just sickens me. :msp_angry:

If it ain't broke, don't fix it. If it is broke, fix it the right way. Don't hack the #### out of something to make something else work, it's improper and stains the name of the car/truck.

In fact, I'd personally love to drive a deuce and a half over a car that has been all ####ed up by like that. That's how much I despise the idea. I despise hacked up cars as much as I despise those idiots with giant wings and fart cannons on their cars, complete with those stupid altezza taillights and a ####ty body kit. My Maxima, even as old as she is with all of those rust bits falling off, would literally humiliate one of them ricers.

-----------------------------------------------------

Tomorrow, after work, I will be helping Lenny with the barn clean up... if I heard right (remember, I'm in a loud ass factory with presses stomping the #### out of steel) he said he is working tomorrow. My dad works until about 5. So I plan to hitch a ride with Lenny and hopefully we'll uncover some old, dusty, and slightly rusty gold in that barn. Pops would arrive after finishing the number stomping on the computer.

We'll see. I will have the camera with me. Laptop too, but I don't think there is any wireless internet or even hard line internet this far out in the farmlands. Yep, it's that rural, lots of guys with missing teeth, probably from drinking lots of Mountain Dew, and not brushing their teeth at all... they are the real guys. Lenny's dad is a nice guy too. I mentioned a while back that I received a few 80's Ryan trimmers from him, and most should run with a little work. (mom still doesn't know about those trimmers... )

I'm imagining this little 1500 pound capacity trailer sitting on flat on its leaf springs, and the back of the half ton Burb full of good old iron, almost to the point of sagging... wouldn't that be neat?

Never met a crotchety old 19 year old before. :msp_scared:

Too bad I won't be around to see what you are going to be like at 80. :hmm3grin2orange:

No, its just rubber.

All I'm saying is hit it with some silicone and put in a ziplock. Keep it away from the sun and high temperatures. Not all that intricate.

Maybe so .... I'm thinking more of an 'old soul' ..... but I like a lot of what I hear from the kid. I count myself among his supporters.

BITD, I'd hear myself referred to as 'delightfully abrasive' and 'refreshingly off-center' .... so I can relate. I'll go to war with ya, Kyle.

I'm an oddball, that's for sure. Crotchety, check. Old, no check. Angry, big check...(sometimes)

Jeff, here are the numbers for the Stihl and McCulloch intake boots (connector) as well as a side by side comparison.
