Title: 011 AV
Post by: Jim_I on December 03, 2012, 04:43:45 pm
Got an old 011 AV that my Dad had but couldn't keep running.  After some fiddling with mixtures I can keep it running do about 20 minutes of cutting.  Then when I squeeze the throttle it tries to die.  Been reading some other stuff that suggests leaving gas in it all winter is not a good idea, although I keep mine treated with Stabil.  Anyway, others have suggested that the gas line might be **** and/or the carb might need to be rebuilt or replaced.  It's a handy little saw to have around.  Any ideas?

Most likely the carb needs rebuilt would be my guess .No sense nurse maiding just get-er-done .

Just do it all in one clip.Clean and rebuild the carb (kits are cheap on ebay),fuel line and fuel filter. The impulse travels through the intake block, you'll see a very small hole. Make sure you line the gasket up correct.
Any troubles just post back here for help.
Their good little saws.I have 2 I won't part with.  Scoot

Pulled the carb this afternoon and both fuel(?) lines broke off.  One of the lines has some sort of brass plug in it.  What's that all about?  I'll go to my local chainsaw shop in town and get some new fuel line.  Gotta make sure I get that metal plug back in correctly (I presume it's supposed to be there).  Are there some sort of written directions for this stuff that I can download and print?  Thanks for the suggestions.

You are probabley better off to use the OEM style line in the tank  .I presume the line with the plug is the tank vent line .That brass contraption acts kind of like a check valves so all the gas doesn't gush out all over the place .

That model lists two carbs .WT 29 Walbro or C1 S S1 Zama .Tutorials on rebuilding can be found on each respective web site of the manufacture .

I have one 011 in the shed I've never used .Got it running ,made a few cuts and there it sits .

There probabley isn't anything wrong with it other than the fact I've got better saws for the intended type of work these things were made for .

Only one I have ever had stihl 011AV and it was found in the landfill in case by a friend that worked there. Went through it and sent it to live in TX.

There must be two versions of those things .I repaired one a few years ago that was orange and had a cable throttle linkage .I could not believe one of the local Stihl dealers had one in stock . I think it's an 011 I have in the shed but it's white .
Title: Re: 011 AV
Post by: Cut4fun . on December 06, 2012, 01:26:02 pm
I've seen early orange and later white ones in pics.
Title: Re: 011 AV
Post by: Al Smith on December 06, 2012, 02:44:46 pm
Yep it's an 011 just like I thought .Evidently the white one is designated 011 AVEQ .It has a fuctioning chain brake and if I'm not mistaken that orange one I wrenched on did not , just  a guard .

Ya know that thing weighs just about as much as the 024 in the picture ,has about the same displacement but  isn't half the saw the 024 is .

I have no idea what the intended market was for these things

I seen alot of white 011 but only few of orange ones. I got 2 white ones but one is in pieces. One has old style choke lever that goes up and down and the other has the newer style choke lever thats goes left to right.

Post by: Cut4fun . on December 06, 2012, 02:57:48 pm
Yours is different then the others I had seen in white.   ???  Must have just made different handle designs using the same motors. 

Yeah I wasnt to impressed with the one I had. My little  poulans 36cc 38cc 40cc would take it's 41cc lunch
Title: Re: 011 AV
Post by: Al Smith on December 06, 2012, 04:02:18 pm
About the same for me .When this thing showed up all I had close to it was an s-25 Poulan and it would walk away from the 011 Stihl .

I looked at the IPL and from what I can decipher this is a real old type  of design which is surprising in 1981 .Oddly it shows the rod and needle bearings sold as a seperate unit from the crankshaft which I found odd indeed .Unless it were made in such a way it could be disassembled without special tools  which I've never seen on any saw with a captive rod .

Like I said for no larger than it was it cut okay but did not exibit that typical Stihl zip .After looking at the design it's very evident why .It was never designed to be a race horse .

Even the current 211 has a slide off removable rod and a single counterweight crank. I think it is the same cc as the 201T?

 When you pull the jug on the 011. You need to be extra careful or you will loose all the big end rod needle bearings into the crankcase. Ask me how i know...
Title: Re: 011 AV
Post by: Al Smith on December 06, 2012, 07:53:29 pm
Does that crank pin just fit together or something ? I mean I've been to two county fairs and a goat roping and I've never seen anything like that .
Title: Re: 011 AV
Post by: 660magnum on December 06, 2012, 08:03:19 pm
the cranks only have a counter weight on one side. the rod will just un thread off the crank shaft and off one end. if you wiggle the rod, the rollers fall out. you have to put it together with wheel bearing grease to keep the rollers in.

They are just needle bearings that are loose in the rod. I had to use grease to hold the bearings to the crank so i could slip the rod end back over the crank. PITA
Title: Re: 011 AV
Post by: Al Smith on December 07, 2012, 05:14:18 am
I understand about the bearings but I don't understand how you get the rod end over the pin .

Now I can possibley see where you might be able to slip rod in  place on the side opposite end of the counter weight  and drop the bearings in from the throw side but then what keeps them from slipping out sideways ?I'm missing something here .

This is one odd design .The thing shows needle bearing mains both sides .Kind of  like an 020/200T with the roller bearing mains .I got no idea how they hold the side thrust unless it's got fiber thrust washers  in the mains  like the 200ts' which are the weak link in that design . Why good heavens the longer I look at this thing it's a wonder it holds together at all .

The piston/cylinder holds the rod in position.

There are slight shoulders on each end of the crank pin location.

As long as the rod is in position over the crank pin, the needles or rollers cannot come out because of the shoulders.

At assembly, the needles or rollers must be stuck onto the crank pin with grease so you can slide the rod over them.

At disassembly, you cannot get the rod completely off the crank unless the crank shaft is completely removed from the flywheel side of the crankcase.

The 35 and 40cc Quadra engines from North American chainsaws of the late 60's through early 80's were made this way. They were used in the more modern looking Lumbards and other chainsaws of the period. These chainsaws had a clamshell engine design but the cases were metal as plastics still were not stable enough.

Post by: Al Smith on December 07, 2012, 09:45:10 am
I've got a couple Lombards but they are of the Al-42 series design .68 cc or something .I'm not certain about all of them but one that cooked it's top end is in a box  and has a pressed together crank much like a Stihl which I found surprising for circa 1968 or so .

You look at some of these designs and wonder what they were thinking .Like McCullochs grand plan of using the piston pin bearings pressed into the outside of the piston rather than on the rod end ,terrible idea .Then on the other hand the danged things held together for years so it obviously worked .

Post by: 660magnum on December 07, 2012, 10:47:12 am
The Quadra 50 and bigger had a double sided counter weight on the crank.

Finally got the carb rebuild kit for the Walbro WT29, fuel line and tank vent line.  I was gonna do it this past weekend, but Dad's neighbor brought down a 34" Black Oak and asked if I wanted the wood.  Dumb question, but I graciously accepted.  So, now the rebuild is put off another week.  Question - I tried pulling the fuel tank filter and it is either stuck or attached.  Do I have to separate the two halves to replace the fuel and vent lines?  How big of a pain is removing the jug, piston, etc?  Never been this deep in a repair before.  Should be fun!

Wow! I'm way behind on this rebuild!  :o  Also got tied up rebuilding my Husky 55 (am I allowed to mention Husky's in a Stihl forum?)  Anyway, I did separate the case so now I need to get a gasket kit and I also discovered the piston has a hairline crack so gotta get one of those as well.  Parts everywhere!  I'll get busy on this, but just wanted to post to get this thread back to the top so I don't have to go hunting when I have questions!   ;D

Post by: Remington on February 17, 2013, 07:59:48 pm
I got a couple of these too with problems. Let us know what happens. 

You do not have to separate the case for a fuel line. A pair of tweezers or needle nose will pull the hose out enough that you can cut off the filter and sacrifice a few millimeters .. and then just pull out the rest through the carb side. The hose is just generic 1/4" or something like that and it's a bad design as you probably realized by now. you'd think there would be a grommet or something but the hose just pushes through a hole with no protection.
Title: Re: 011 AV
Post by: 660magnum on February 17, 2013, 08:19:30 pm
The hose should fit the hole snug though
Title: Re: 011 AV
Post by: Jim_I on February 19, 2013, 06:37:28 am
Too late, the case was split.  No biggie.  I did get new fuel line and as long as everything is apart I'm gonna replace the vent hose as well.  Already have the vent plug back in the hose.  Pushed it in, didn't screw it in so I should be good there.  A piston for this little bugger isn't cheap ($75), but you have to be careful as it looks like some of the 011 models used single ring pistons.  Mine is of the double ring variety which, it seems to me, makes the piston more stable in the cylinder and also gives better compression. 

Yeah, it looks like the hoses should have been passed through a grommet rather than a metal case.  I think part of my initial problem with the saw was a **** fuel line.  When I pulled the carb the fuel line broke right at the spot where it went through the case.  Probably pretty common.  The real reason I split the case was because the fuel filter wouldn't budge.  I was worried it was attached and didn't want to bugger something up so I decided to split the case and see what was going on.  As I was pulling the case apart the fuel filter fell out.  Don't know what was jamming it up, but something was.

If I can get a second saw back up and running I'm likely to break my arm patting myself on the back!   ::)

I had the 009 out today. Cut fine on a few branches and then it didn't want to start the second time, could be because it was sitting in -5C for 2 hours. I got it started for a bit but it sounded like crap.  seems to work better in warmer temperatures.
Title: Re: 011 AV
Post by: Jim_I on February 22, 2013, 10:14:30 pm
More than half-way there!  Had a rough time getting the cylinder on and keep in the bearings on the crank.  Had 'em greased to be sure, but couldn't figure out how to get the piston in the cylinder without losing one or two bearings.  Finally figured it out on the fourth try:  put the piston in the cylinder just past the second ring, put the gaskets in place, slide connecting rod over bearings and push case halves together, then bolt down cylinder.  Presto!  The hard part is finished.  I'll get the rest of it finished tomorrow and hopefully it'll start!   ;)

sounds like four hands are needed?

I'd have to use some of the old style waxy stringy heavy wheel bearing grease?

I'm just waiting on a few parts myself.  It turns out the fuel hose I was using is .005 mm too thin. I filled it up the other day and put on its side and today it was half empty.
Title: Re: 011 AV
Post by: Remington on February 28, 2013, 05:09:27 pm
Any suggestions here for a fuel line work around.  The dealer was a snake and pretended its generic because he didn't want to order a $5 part.

 Of course it isn't generic and the first tygon I tried is too thin and leaks and the one he sold me yesterday is too thick and can't even be pushed in with a screwdriver.

I'm trying to avoid having to go back there for a $5 sale, since I'm not buying a kubota tractor for cash they get really upset.

You could drill out the hole to fit your new fuel line. Or theres always Ebay
Title: Re: 011 AV
Post by: Remington on February 28, 2013, 08:53:23 pm
Drilling was my first idea but I didn't want screw it up.  I found something better and a temp fix is in.

I took the end of a old fuel filter and snipped it and cut the fuel line halfway and inserted the fuel filter piece to act as a coupler. It expanded the tygon just enough to make a good fit at the wall. I will try to find a longer coupler but this fix is fine for now.

Post by: Remington on February 28, 2013, 10:58:36 pm
Here it is 20 minutes ago with the new tygon lines.  The vent hose is just dangling in the hole but it works great as is. That was some dead wood but it did go through pretty fast

Some 015's have the same design of individual roller bearings,with a removable rod.
