Not a Stihl guy helping a friend

[WKEND LUMBERJAK]

How does a non Stihl guy tell the difference between a 066,660 , piston is 54mm. The tag is missing on the air filter cover. Has 1122 ******on several different parts. No floppy caps. Piston and cylinder are extremely scores and lots of transfer. Thanks for any input

same saw same parts

 

[WKEND LUMBERJAK]

What should a piston and cylinder OEM cost

 

[Warped5]

IIRC, an 066 (1) has smaller cylinder hold-down bolts than a 660 (2) the flywheel nut off an 044/440 will fit an 066.

@jmssaws

I think the MS660 started with flippy caps. 066 had regular caps.

 

[dall]

the 066 and 660 did not come with flippy caps the first 066 had a small crank told by the aluminum flywheel then they switched to the poly wheel only difference i know is the top plastics all the bolts cylinders and parts will switch over from one to the other all the 066 and 660 had the m6 bolts to hold cylinders on same as the 046 the 044 and i think the 064 had the m5 bolts jason would know more

When Stihl switched the models to MS all the saws changed to flippy caps with the MS660 being the exception . This was in around 2001 .
The new saws sat in the warehouse till the old style were gone .

 

[dall]

not on the 660 they didnt

 

[dall]

i have 2 flat top first 066s with the aluminum flywheel and small crank also a 066 and a 660 with the poly flywheel

When Stihl switched the models to MS all the saws changed to flippy caps as well . This was in around 2001 .

Ahhhhh.....no. Just sayin.

 

[Nitehawk55]

Sorry , I corrected that , been a while the ol brain getting foggy on some things .

I was close with the MSxxx series for Flippy caps. Lol
I have a MS440, not a MS660. Lol
Close but no cigar.

Is the mmws top end in production yet? If so this could be a route for you kenneth.

Call again if you have any more questions fella

I had an old 066 with the small crank and metal flywheel. Still got the flywheel out there. And the coil too. The coil was different, I think it is like a dogleg style coil, IIRC. 066 to my knowledge is just like dall explained. The later 066 had the curved tops and screw caps before they changed to the 660. So parts should interchange betwwen the two.

my flat tops with aluminum flywheel still has the original coils jason said i should find a spare so if you want to part with your spare parts id take them off your hands

Any coil from 026 up will work just fine on your saw

Man this shipping is getting expensive!!! Lol Maybe we can work something out.... Lol

There is many variations of the 066/660
The very first 066's are a 064 with a different oiler and flywheel and starter.

Have you got a flat top or bubble top?
Does it have a orange stihl badge in the middle of the starter or is stihl cast into the starter under the handle?
