Title: Clutch tools and flywheel removal tools
Post by: Cut4fun on January 14, 2012, 10:34:09 am
Just another Thank you for a clutch tool Al Smith made me to take clutches off the dolmar 166 back when I owned them (had one stuck on the racer and it would not come off with homemade bar with studs or 3lb sledge and punch method).

The other day it was the only clutch tool that came close to fitting a dolmar 111i and I was able to remove the clutch easily.

Even though I have a clutch tool for poulans, its for the smaller ones  >:( . Come to find out I think that clutch tool will fit the bigger poulans I have in the 330 etc. So I will no longer will have to use the hammer and punch method with them. 

So what other methods are guys using to remove their stubborn clutches or flywheels?

There has been talk of taking a scrench and on the big end to cut out slots with a cut off wheel to make the scrench fit the clutch hub. Then to use your impact wrench and a socket over the small end to removed clutches.

Near me there is a surplus store that has all sizes of misc. screnches.

Some of the Stihl clutchs can be a bear to get a socket on .Not much "nut" sticking out .

A standard socket has a tiny bit of taper on the end and as such doesn't gain purchase on the nut .My hillbilly fix is to chuck up a black iron socket which I have by the buckets full and trim the end down in the lathe .You have to use carbide because the socket is made of heat treated 4140 steel and is hard as nine miles of bad road .

I suppose if nothing else you could use a belt sander and get the same effect .

My clutch removal tools
WOW!!! Bought this tool 20 some years ago for like $30.00.

http://buy1.snapon.com/catalog/item.asp?.... store&tool=all

It is truely a great universal clutch remover tool. All brands.
Has 2 set of pins 1/4" x1/2" long and 3/16 x 1/4 long.
Either insert tool in pin holes in clutch hole or in gap between clutch shoes.
Works like a charm.
Also have made some out of 3/8" x 12" key stock. Drill ends for size pins you want and put a # 41 roller chain connector link in holes on other end to hook then together like a hinge.
Also works great and can cost as little as $5.00 . A very usefull tool for a bargain price. You can truely feel how tight it was and know you got it installed fairly tight. If not tight they can self loosen sometimes if you start a saw up without a bar and chain on.
I try not to do that unless the clutch has a keeper or nut to hold it on. If it comes loose it can fly A LONG ways!! Hopefully not right up your forehead!! Saw that happen once!!

I have one of these. It is all forged and black. Looks rough like it was made in a country blacksmith shop but it works

http://www.amazon.com/Stanley-Proto-JC483-Adjustable-Capacity/dp/B002759GP6

It has 1/4" pins and 3" capacity. Proto makes another that has 3/16" pins and is 2" capacity.

We call that thing an adjustable pin face spanner at work ..It's used as a rule to take certain couplings and gears apart on machine tools .Meaning high speed automotive type manufacturing .I've got a few myself .

Problem is I'm not sure how they would work on a chainsaw clutch because  they are pretty tight ,might be okay though .In many instances  on machine tools they are snug but not tight as a bulls butt in fly time and  they have a back up locking gizmo to hold them in place .

The one that Cut4fun has that looks like yours sure works nice.

I've never used my adjustable pin spanner on a clutch. I'll have to try it for that?

I've used it for 25 years to get angle disk grinder nuts off - on.

Same one. I just used screwdriver shaft for pins to keep from shearing off the hollow pins.

LMAO why didnt someone bring to my attention I spelled flyweel wrong. (http://i59.photobucket.com/albums/g289/doemaster789/smiles/canspellsmiley.gif)  NOT!


Has anyone ever tried this style of flywheel puller?
Title: Re: Clutch tools and flywheel removal tools
Post by: Al Smith on January 22, 2012, 07:26:07 pm
 Those were "pull dowels " which have a thread in them for extraction from a blind hole .They were only ones I could find at the time .

A lot of this home grown stuff is experimentation .Usually it works after a few minor adjustments . ;)

Problem with a screw on clutch is they get tight as a mouses ear .What ever you use often times has to be able to with stand some impact because it often takes a mighty wack with a hammer to get it broke loose .

You can take a chance and thump them on the clutch spinder with a brass rod and a ball peen but you take the change of doing harm to the crank shaft stub end . Not good .

Some very crude tools I have made up.  No lathe here so nothing very fancy.  Borrowed a buddies wire feed welder (I never welded before) to make the partner oiler gear remover gizmo in the back.  It's made from a 1/2-3/8" NPT adapter and various pieces shown on the second photo.  The threads on the 1/2" end are 14TPI which matches the oiler gear, but it's a little too large in diameter.  Just shove a small piece of string or rag on the threads to keep things tight.

Flywheel pullers on the left (minus the screws/washers needed) and clutch removal tools on the right that are used gently with an impact wrench.

Solo 665-681 Clutch tool.  Everybody has a bunch of old spark plug sockets in their toolbox.  I used a Dremel and a 1" cutoff wheel to cut out every other face about 3/8" - 7/16" deep.  10-15 min.  Done.  I think it will work on Dol/Mak 6400-7900 too.  Will have to check.

That brings up another little trick .On some Stihl clutchs with a little nut like projection the champfer on a 6 point socket just will not gain enough "purchase " on the nut .Simple fix ,belt sand the champfer out of the socket until it's straight smooth .

Just throwing this out there. Dolmar 166 flywheel removal tool.

I found out that the POLY flywheel removal tool for the stihl 066 660 will work. It is the same threads as the dolmar 166 flywheel since I owned both saws.   ;)

JFYI  Yesterday I was taking clutch off echo 6700 which uses 3 prong. I was able to take a poulan with only 2 prong and off set it and remove clutch needing 3 prongs.

So now that is 2 more clutch tools I want.  ;D

Title: Re: Clutch tools and flywheel removal tools
Post by: Al Smith on September 03, 2012, 05:15:09 am
In looking at that tool it might be such a thing as a more "universal " type might be possible to make by threading a series of hole around the circumferance and using grade 8 cap screws .

The problem with the 166 Dolmar was the fact it went into square holes which of course was over come by the adaptations from the screwdriver shaft .Whatever is used for the "prongs " has to be some tough steel .

I wonder how close this older style echo 3 pin clutch removal tool  is to fitting your 550 clutch.

I just make them as I need them from a old socket or buy a cheap socket the right diameter.

Thats how I started out making out of old sockets. But I kept breaking the tabs off on poulan ones on stubborn clutches. So I gave in and bought cheap oem priced ones.

It looks very close. The distance between pins on mine is 1.035" The pins are .34" in diameter.

Just a update. The echo 3 pin clutch tool does work on the husky 550xp

I had a bar that has 2 studs in it (came with saw from Nova Scotia)  for doing 166 clutches till Al made me the tool.

Al made me one that I could adjust the pins.

Red neck engineering on display....one vid was a home made tool for a clutch with two weights, the other a bought tool for 3 (372's) Pretty simple stuff. Also in the second video simple flywheel removal tool/technic and case splitting tool. Second video has a more "stubborn" clutch. Socket's or clutch tools, air impact wrench and a rag brought to bear.

Home made clutch removal tool made on the fly for a 455....in this vid somewhere
https://www.youtube.com/watch?v=LEV2gtuWxOA


Breaking down cases to replace main bearings is what this is about. Removing 372 clutches & flywheels the red neck way in here somewhere as well.

I had a Stihl 660 in here that I could NOT get the clutch off of, in fact when trying to do so I slipped and buried the top tooth of the inner dog about an inch into my left forearm. Well after a trip to the doc for 12 stitches I was back at the shop and the 660 was on my bench with my blood on its' face laughing at me.

So I thought about it for a while and decided to try a little reverse psychology on the smart azz bazturd. I put my rope back in the jug so it was blocked from turning anticlockwise, then I used a rattle wrench and gave it about three or four burps to tighten it up, then re blocked the piston, and one burp and the clutch was off. Very old trick I learned from a tractor mechanic when I was a kid

I miss placed my poulan clutch tool and went looking for something else to use and in my auto brake tools had a tool for running the "ratcheting" rear disc brake cylinder shafts back in for pad swaps.....it's a square with 6 different 2 prong setups and hollow with each face accepting 3/8" drive tools....worked great!
