Stihl 011 AVT questions.......

[xdmp22]

Got a good deal from o8f150 on a used 011AVT......needs a carb kit and AV mounts. I ordered the AV mounts....they should be in this week.

Before they come in, I want to give her a good cleaning....I know its a silly newbe question but what is the best way to get the clutch off?

I have breaker bars, impacts, butterfly impacts, punches, chisels, hammers.....you name it.

Is there a special removal tool for these? Or should I make a spanner tool?

Also, what direction does it remove? Is it left hand threads or right hand?

here is a pic of the clutch

and here is a pic of my idea of a tool and where I would put pins for the spanner.

red or blue depending on which way it comes off or tightens, but pin distance between centers would be the same

thanks guys

Oh, and I should mention, I made a custom steel/brass piston stop already from the old sparkplug and misc crap from my shop......

Make your spanner tool so that the pins fit in the holes in near the center of the 'S' spring clutch hub/shoe thingee. That's what those holes are there for. You don't want to put force out where your red and blue dots are in your pic. Remember that the 'S' type clutch is a giant spring. LH threads BTW.

Thanks, after looking @ my pics, I had that thought as well about the holes and the flexing of the outer parts.....Ill probably mod a socket or make a spanner this week.

I figured it was left hand threads, thanks for confirming.....rep inbound asap

There is a nice cheap spanner made to remove there clutches. I picked one up off eBay for a few bucks. I like that piston stop!

Ill take a look over on flea bay.....though, I love custom tools so I may go that route as well.....I have to fail atleast 5 times usually before I give up and just buy the tool.....lol

The piston stop was pretty easy, just bust up a spark plug, then some file work. The center hole was already sized close to the tap drill for 3/8-16 (about .020 to big, but should be fine). Then I just used a brass bolt....its 1 1/2" or 2", I had both, not sure which one is in pic. Nice and adjustable.

Thanks for the info. I've got some old plugs one the bench, so I think I'll make one. Tired of using the rope trick.

When you tap, tap from the spark side, not the porc. side.

The first 2 I did I tapped from the porc. side because it was tapered and seemed the best, but the ended up @ a sever angle for some reason. The third one I did from the spark side and it is perfect.

Got it, thanks. Now I have to dig out a brass bolt from my not organized stuff pile.

I know how that is, I have been organizing my shop for the last 4 years.....lol

I did however have all my brass bolts in a single bin.....so that was easy to find......

Use a pair of needle nose Vice Grips locked down closest to the crankshaft. They fit nicely in there. Then use a flat bar or suitable tool as a t handle between the jaws of the Vice Grips. I just used this method yesterday. Slick and quick.

That's down and dirty for sure......maybe adding some small hose on the jaws would be a good improvement.....I may just try this and see.........

Thanks

not sure if I have the right vice grip though..........

If you use that setup in a saw with an angled sparkplug hole(modern saw) you will damage the piston, as with most piston stops.

Use an impact wrench or rope, not both.

thanks for the tip......I figured on the angled deal, the 011 has a straight down plug thus the need for the piston stop.

I am also working on a few more stop designs with rubber tips.....we shall see what I come up with, I brought home a bag of moddable possibilities today.....lol

Let me raise the bar a smidge;

 

[bplust]

I've never had one of those saws in my hands, but regardless, I doubt it could be assembled much differently than the rest. I'd put of piece of clean rope down the spark plug hole as a piston stop that won't damage the piston and unscrew the clutch (reverse thread most likely). Cheapest and hasn't failed for me yet. Good luck!

More Vise Grip stuff............

I hope your Stihl 011AV project turns out well. I've got one also, it was the last saw my father used and it's very special to me!! Thanks to your thread I now know how to do the clutch removal which is something I'd been wanting to do.....lubrication of the clutch hub bearing!!

I hope the Vise Grip tangent isn't tooo distracting from your thread.

As noted by last picture in my previous post I've been to DeWitt, Nebraska.......the once proud home of Peterson Manufacturing. That company was started by William Peterson, the inventor of the Vise Grip!!

My friend and I even went out to the cemetery to pay homage to William and his son Christian Peterson.

All I can say is I'm CERTAIN William Peterson would be rolling over in his grave if he knew what has happened to his once proud American manufactured tool business!!

 

[xdmp22]

Nope, I have been to DeWitt as well, a month before they got bought out.

I too have some rare vise grips, Ill post them up tomorrow.

Glad to see the pics and help out with the 011.

I also did a sculpture for vise grip back in the studio days, Ill see if I can find those pics to.

We sell vise grip @ my work, and the quality is sure not what it used to be............

Thanks again
