Old sthil saw question.

[alleyyooper]

Have a old 032 Stihl saw that was my dads. He got it back in the mid 1970's ran it for some time then is sat for a long time. Any how both my mom and dad passed away so I have been clean up the old place to sell and ran across this saw way under the work bench. It is seized up so I would like to try to tear it down and see if i can get it running again. Problem is I haven't figured out just how to get the outer case off so I can even start to get to the cylinder.
Any help in that area, I have removed about every nut bolt and screw I can see. I have the cylinder and maybe crank case full of trans fluid soaking.

You have to take the 4 nuts off the head, and work it off very care full, if it don't want to come off let it soak longer.

There is one bolt on the 031/032 series at the rear on the CLUTCH side of the engine.  That one foils everyone on their first time.  Good luck.  If that saw does not have any spark, lets hope it has points.  Those electronic ignitions can ba a pain, and they are not uncommon to fail.

The 032 was the first saw I bought.Used it for about 5 years.Than the seals started leaking every wheres in it.A nice saw all those years.

[Saw Dr.]

Just wondering if you got the 032 apart yet?  I assumed from the earlier post that you were struggling with removing the flywheel shroud.  That one does have the extra bolt on the clutch side.  All of the other covers on it should come off in a pretty conventional manner.

The best thing to do with an old saw is to blow all the crud off with compressed air before you ever attempt to disect it .Those case bolts can hid pretty well from you .Sneaky little rascals .

[alleyyooper]

got every screw I can see out and that top cover still feel slike it has a huge bolt thru the center holding it in place.
The clutch is even off to see if I missed one way under it.

Say on this old saw that seems to be causing much  gnashing of teeth it lists 7 case bolts .I counted 8 holes but maybe one is for the bucking spike or Stihl forgot about one .

Don't forget though that even if you find and remove every one of the elusive little rascals those case halves have shink fit bearings attached to the crankshaft still plus two dowel pins .

If you can find the dowels they usually can be driven out from one side or the other .

One way to pop the bearing loose is to heat the bearing pockets with a heavy duty electric heat gun as the aluminum will swell enough to let you pop the crankshaft with bearing out .You might try it and tap it ever so gentley with a wooden mallet,dead blow hammer or something .Don't thump it with an 8 pound sledge like you're driving a railroad spike now .It'll come apart with enough finess

Not trying to get the case apart nor the cylinder off I'm trying tpo remove the cover part that fits over the cylinder just so I can get to that part. Glad for my dads sake there was a way to change the spark plug with out removing that stuff.

Well ,don't give up the ship just yet and take a ball peen hammer to it .I'll take a peek at my mico films  .It might add some light to the puzzle .

[Al_Smith]

Aha,got it .You've  got an AV mount on the right hand side up forward top of the cover .Two side mounts on a swivel lower rear handle and one collar screw upper forward the av mount .Actually most likely for that mount but it's hard to say without a saw and just an IPL to look at .

I'd say you'd have to disect the handle etc. as it appears to be a one piece handle with fuel tank  and cover .Probabley pull the carb too .

Worse comes to worse just pull every screw out of it ,something will happen I'm sure .Don't forget how you took it apart .We don't want to see an 032 on flea bay in a box in a couple of weeks now .--take some pictures if you think you might "screw up " .

Well fiddle  with it .If you don't hit pay dirt in a day or so I'll break out the service manual and take a peek .No ball peen now .

Says who???  Mine gots no spark.....  Just kidding.  The top AV mount is the hole just in front of the wrap handle where it meets the orange cover at the top right.  You will have to stick a long flat-blade screwdriver in there to remove the center bolt in the mount.  Usually it takes a magnet a bit of fiddling to get the bolt extracted, and the cover will not come off until the bolt is OUT of the hole completely.  It is a special bolt with a couple of shoulders on it.  You will do yourself a favor by making sure the hole you stick the screwdriver through is completely clear before trying to fish the grimy bolt out through it.

[Al_Smith]

From a peek at the IPL it appears those things were stuck together with slotted screws instead of torx or socket heads .Now let me tell you they can be a real joy to remove if someone didn't have the foresight to grease them up with some type of antisieze compound .I mean it takes an impact driver to shake them .

Now if that's the case spend a buck a piece for torx or use socket heads  unless your some type of a purist in rebuilding saws .Use the never sieze too while you're at it .You'll thank me later .

[Saw Dr.]

Sadly, those AV mount center screws are "special" and only avail with a slot head. 

[Al_Smith]

The 038 Mag uses a similar slotted long shoulder bolt for the top mount .It's like a woodscrew thread because of the thermal plastic handle assembley .Those don't stick like glue ,just the ones that are on metal handles like the 038 Av ,042 etc .

[Saw Dr.]

Yeah, just another good reason not to like those brittle 038 tanks.  The 032 screw is just like the ones on the 045 and 056.  May be the same, I'm too lazy to go look it up....  I was wanting to convert one of my 056 MAG's over to all T-27 bolts, but there are several special fasteners on those.  Someday I'll get a lathe and machine my own.

[Al_Smith]

Get a machine that cuts metric threads then because many of us on the forums that do have lathes can only cut SAE threads . On those metal handles  though if you can shake the bolts loose and reinstall torx with anti sieze they aren't a problem .Something of course they should have done since day one but I don't think torx heads were so common place back in the day but socket heads were .

[Saw Dr.]

I am squirreling away a little $ at a time for a lathe.  Main purpose will be milling cylinders, pistons, and making stuff.  I figure in couple of years I can have $1500 set aside and then start looking.  Any good forums for machining?  maybe I should start keeping my eyes open now.  Good point on the metric threads.

OK thanks for the information. No hammers will be used if all else fails I'll run over it with a tractor after  insuring it.

Friend bought a lathe for less than $500.00 of course it is a really big old one and he had to disassemble just about all of it so he could drop it out a 3d story window to his truck below.
