My 660 died - has anyone rebuilt one of these? dealer wants $500 to fix

[Flatheadyoungin]

No, Rosemount but we have bare land out on 140.......

The big town of Muletown.......

Well, dang!   

Southern Ohio.   I would guess West Portsmouth.

So have to heard of Muletown  about 15 north

First - Thanks for all the help

An update: 

Got the new EFCO and have some comments for anyone considering a MT8200
    1. Starts really easy for a mid-large saw
    2. Runs strong - It will mill, though I won't use it for that for long mainly because I think it would be a bit undersized and the location of the chain adjustment screw ends up behind the mill components when it's mounted on the granberg mill.  I did use it to finish the mantel I was milling.  Also -I'll have the Stihl repaired myself (thanks to all the forum responses) this week.
    3. It's quieter then I thought it would be - my bro.-in-law on the helper handle noticed that too
    4. The way it is put together I doubt I will need the warrantee.
    5. It is a bit heavy - smaller cc's then the stihl but it feels heavier
    6. Cuts like crazy
I like it -

My dad burned up the p/c in his 066 on a Logosol.  I like to work on small engines but I have no experience with chainsaws, but IIRC it took me less than hour to swap out the burned up p/c for a new assembly; it's a very easy repair on this saw.  He doesn't use it anymore but I've made some changes to ensure it doesn't burn up another p/c:

1.  Only use 93 octane, non-ethanol fuel with synthetic oil mix, no older than 1 month.

2.  Port the muffler.  This adds a bit of power and lowers the operating temperature.  Stihl sells a dual-port muffler for the 066 if you don't want to deal with porting the stock muffler. 

3.  Tune the saw for milling.  First I tune the 066 with the standard two-cycle tuning procedure.  Then I begin a milling cut, just cut enough to bring up the temperature, on the hardwoods I'm milling 12 inches is good.  Next I back out the H jet 1/16th of a turn, and cut another 12 inches.  Repeat until there's a drop in power, then return the H jet to the previous setting.  This method ensures as rich a mixture as possible while still maintaining sufficient milling power.

4.  Basic maintenance tasks like cleaning the air filter, replacing the fuel filter on a regular basis, running only razor sharp chain with sufficient oil.  This is probably obvious to most people but my dad only cleaned the air filter once per week when he felt like it, forget about the fuel filter. 

Following these practices has kept the 066 in excellent condition so far.

Log Hogger, this is probaly the best post I have seen in print on how to go about a no nonsense practical approach to tuning a saw for milling. The 66's wouldn't be my first choice for such demanding  work as milling, they are high rpm saws and the torque needed to do milling lacks compared to the older Sthils like the 76's.

I know of a few guys that have done the same thing trying to mill logs. Five hundred bucks is not out of line for a dealer to rebuild a saw like that, Sthil parts are outrageous. Gotta pay for that trademark somehow.

If this happened to me and all I had was a 66, I would be checking that bottom end out to make sure the bearings and seals were in good to excellent shape. Putting a new top-end into a saw doesn't mean the same thing won't happen again. You can get by with so,so bearings and small airleaks in the seals if your just cutting wood. Milling is  hard on the bottom end of a saw because of the torque needed to keep the saw moving forward due to the chain dulling down  and constantly running it on it's side.

yeah..roasted my 660..gotta get the gaskets for it..I was cutting hard in a big oak..I'd imagine It was a bit too lean from the factory...I was really working it in the log and with a 20" bar..

One thing you can do to keep it a tad cooler is pull the spark screen out of the muffler...unless you use the saw in dry woods that is..you still have to tune a bit for the added flow, but what else is new..definetly want to run a bit on the rich side for milling, especially if you are pulling a long chain..

[Al_Smith]

With a 20" an 066/660 should be able to cut if the chain was on backwards .

IMO this is the smallest saw I would even consider to mill with .Since they came out with the "Alaska" type milling guides  there has been unnumerable saws cooked from running them .A majority of those saw were in fact 066's .

Milling is tough on the saws .Milling is an option to salvage wood and some enjoy it .

If it were I ,which it's not I'd find a big old reed valve Mac ,Homelite ,Pioneer ,076 Sthl or something that has some grunt . At least 100 cc's .These things can take much more abuse than an 066 . I see no sense in burning up an 1100 dollar saw when a cheaper option could be used .Save the 66 for what it was built for, a darned good faller /bucker .

Y'all  'scuse me, but I almost get a heart attack every time I read the title of this thread on the Forum.  To prolong my worthy life, I'm going to stick a "My" on the front of the thread to keep my heart out of my throat.  ......carry on. 

[Dalden]

Thanks for adding the "my" - I am advised by counsel that my liabilty insurance does not cover inducing corinary problems in others, though the dealer did not seem to mind nearly giving me one.

MY  -   EFCO still running fine even though I milled a bit more with it - Stihl in bits and pieces - but I'll get 'em all put back. I got a service manual from EBAY. 

I wonder - TOM ??  Does the forum have a place where really techy folks could place scanned versions of manuals like that in PDF form for forumites to use?  Idea ?  maybe forum donation to see into that file archive type thing

soory thinking outloud.

My kid just bought a Poulan Pro 54cc to buck my scrap into firewood, now that he has saw dust on him I'll never get him outta here.  Bet he ends up making more $$ then me.  Thanks to the forum advice I'll get him to set his a little rich too!  (the box made a special note that the saw was EPA approved)

Might be copyright issues.

If you do a Google often times you can find the IPL on commercial sites such as parts tree . Others may be contained on certain other web forums but because some sites get a tad fussy about it I won't provide a link .

A few years ago  myself ,Mike Acres ,Lewis Brander ,Magnus ,MacBob and others spent months and months scanning and posting .


With Stihl you can get the operaters manuals on line but for reasons unknown they get a tad cranky about giving out the IPL's or actual tech manuals like it's top secret or something . Typical Stihl .

 You might get somebody to scan and send them via regular E-mail but it takes about 6 e-mails to do that because of the size files .

I bet you could find it in German.

Copyright is always a question that must be considered.  You, and the forum, could get tied up in long, expensive court battles if Copyrights are abused.

There are places on the forum where stuff, relative to maintenance, could be kept.  One is the forum itself.  You just have to title the thread specifically for that item so that it could be found in search.

If there were no room in the post, then "additional Options", below the Photo Upload statement, will allow certain sizes of documents, like PDF's.  That is what it is for.

You could also provide the information, by either copying a post, or typing your own, and putting it on the "Knowledge Base".  You get to it through Forum Extras at the top of the page., in the banner.

If you use the knowledge base, it's best for the info, or a note saying it is in the knowledge base, to also be in a post so that a search will find it.

Never take copyright lightly.  It is serious law.

[Jeff]

I doubt if manuals have copyright notices in them but I could be wrong.  Al, have you ever noticed one in any of the manuals you scanned?

[SwampDonkey]

Depends on the manual. A user's manual probably not, but a service/repair manual I wouldn't be surprised. My friend's father was a traveling salesman with service manuals and they were not cheap to buy, so I assume someone has copyrights on some at least. And because a manual can be found on Google, doesn't mean it's not copyright. They are treading some thin waters. There has been much discussion over scanning and providing documents online. Google has been kind of sneaking bye, by just displaying parts. Some documents state that copying even parts of them is forbidden without permission. My brother purchased a PDF version of an Elan snow sled repair manual, and they won't touch it at Staples. Staples offers a printing service for files and they won't print it. In Adobe Reader it says it's a "Secured" document. Allows printing, but not content copying or assembling for publication.  He has no printer of his own, so he comes and prints a page or two at my place.

[Al_Smith]

Actually I never scanned a manual only the IPL's .The only manuals I have and those being tech manuals are Stihl and McCulloch and those are on microfiche and I have no way to copy them as such .
The Homelite stuff is all contained in a large book which covers all models but keep in mind they are all old as the hills .


I wouldn't put at risk some web forum though by posting the IPL for that matter .However as I see it those IPLs are my property because I paid for them ,dearly I might add .If I as a private person want to loan them to someone for no profit what harm is that ?

Now I could see the almighty Stihl making a big fuss if I sold them .The operators manuals I suppose are nice but all things considered really a saw is a saw they all work the same .Nice perhaps to have but not a "must have" but opinions on that may vary as they should .


As I typed this I took a peek at my Stihl IPL's which are in a big dealers book about 6 inches thick .I don't see any place is says one thing about copyright unless it's in German .Fact is the one and only manual I have for Stihl,042/048 doesn't say anything either .

This is a part from the introduction of the MS660 workshop manual.
I think the bit I have highlighted could be taken to mean that passing on technical info is not smiled upon by Stihl
