Stihl MS 661 32" bar size maximum?

[MCW]

Was running a brand new 661 a week ago with a 36" .404" .063" Stihl ES bar with Windsor semi chisel non skip on a 7 tooth rim. Did it easily buried in dead Sugar Gum which is HARD stuff and harder than basically anything you'd find in the states. Was a very impressive saw. With the oiler pin adjusted there was ample oil. Saw was an Australian delivered model bought by Ben (Bennn*e).
.063" bars will definitely carry more oil as .050" bars tend to pack out the groove with woodchips a lot easier. Not all timber species tend to pack out the bar groove but it's not uncommon in our timber to have woodchips jammed that tight in a .050" groove that it is a real struggle to get them out even with a bar cleaning tool. You don't see this in .063" bars.
If Stihl started saying that you could run a 42" bar on a 661 they'd never sell another 880

Piltz kit I see haha

PILTZ ?????
thats a FREAK 066 (if you ask me) !!

 

[G-Man!!!]

The 0.063 is a ***** to sharpen tho. Had to buy heavy duty files.

HuskStihl - If I'm not mistaken, .063 and .050 is a reference to the size of the drive link. Other than the drive links being different sizes, the .050 and the .063 should sharpen the same???

Two things ..............
#1. Awesome post !!!!
#2. I had a mutha scratchin hard time getting my 36" .404 setup on my 661 with a 7 pin. Had to drill new bar holes. Did you get a chaince to look at the bar itself with the side cover off ?

Yup. I've never run a 661 with a 42" bar in hardwood but in pine, fir, or cedar they do a fine job.
Anything over a 42 I'd probably reach for that 880 though.

I run a 16" bar on my 661. I think my oiler is up to high because I have to fill the oil tank twice before the gas tank is empty. .......

I always thought .050 was for homeowner saws?

We had no dramas mounting the 36" ES in .404". Clearance off the rim and bar adjustment was fine. It may just be your photo but are you sure the bar you have is a 12mm 3003 mount bar? It looks like you have a bit of clearance between the bar studs and bar slot. It's not a 14mm 3002 mount bar is it?

You have the wrong bar sir,a regular. 063 3/8 bar is the same as 404.just the bar tip is different and the drive sprocket has to be 404. That bat may be for an ms880 maybe?

Both chains share the same cutters so yes sharpening is the same different brands will differ though, stihl has the widest kerf I have found so far

I've had good success with a .404 picco setup with a 9 pin on my 445. The saw is running belRay at 32:1, so it's quite a bit stronger than stock however.

I forgot, was this thread about whether a 90cc saw can run a 36" bar, or why would a manufacturer specify a particular bar length? I know the answer to both, just PM me if interested.

If it won't run a 50" I'd throw it in the trash

I was going to say we need a video for proof and scientific reasonin', but I see you covered that too.

You spelled troof wrong, dumbass


Edit: I stopped taking this thread seriously a few pages ago, if y'all are still being cereal, I'll pull it together

066 cutting:

That's how my 660 cuts, but I have to go through logs half again larger dia. That's the way elm and cottonwood grows around here -- big. So, the 661 is worth another $350 today? Seems hard to believe.
