MS211

I posted this question on the other site this morning and have
not gotten an answer yet, so I thought I'd give you guys a shot.
When I replaced the oil seals I used 9639 033 1585 that says to
use if engine is opened up. It goes on to say "slip the oil
seal, closed side facing the engine over the crankshaft stub".
OK, that's pretty clear EXCEPT that further in the manual it
says " push new oil seals, open side facing crankshaft, onto the
crankshaft stubs" WTF?????
Same seal part#
What 's going on here ? I'm totally confused now as to which
installation instruction is correct. We debated yesterday as to
which direction to install them, but always came back to the
original statement about closed side facing engine even though
it went against logic. It was just by chance today I found the
conflicting information.
Which is correct????

Never mind, I just viewed a picture of a 211 engine. Closed side
out. Why would Stihl put conflicting information in the repair
manual??
Oh well, live & learn.

All the seals on crankshafts for chain saws no matter who makes
them always has the lip of the seal where the spring is facing
toward the engine.
That would make the closed side facing out.

That's what I thought but because of the conflicting information
above (which I didn't see until that evening), I went with the
first statement even though it just seemed wrong. I've never
totally tore down a saw let alone a Stihl.
I've asked a lot of dumb simple questions because of my
inexperience that the rebuild experts are probably shaking their
heads over and thinking "what a bozo"! :-\
But for me it's been a learning experience that will carry over
to other brands IF I ever decide to go through this again.
Now it's back to pulling the engine, split the case, reverse the
seals and give it another go. >:(
Thanks and have a good day.

It is the way seals are designed to work and not the saw.
We all started where you are right now so ask away.
Remember the crankcase has to hold pressure and vacuum and those
seals are designed to do that.

It's fixed. It was soooo much easier the second time around. :)

Got it back together last week and finally had a chance to put
it to wood.
Started on 5-6th pull, reset the idle and carb jets and just
pizz revved it a little not over doing the rpm. Played around
running it for about 1/2 hour.
Put the bar on today and went a cutting. Nothing big and nothing
long term under load. Sweet saw, runs strong. I'd like to see
the oilier put out more, but it's getting it done.
Went through about 3/4 tank of gas, let it cool down pulled the
muffler to take a look. One faint line but otherwise piston
looks good. I had nightmares about not getting all the transfer
out and trashing the new piston & rings. Hopefully I've avoided
that.
It seems to be leaking oil around the grommet in the tank. I'll
have to take it to the dealer and see if they'll still honor the
recall/fix that Stihl put out.
Have a great day
