Removing flywheel
By: Giles Date: April 2, 2015, 1:36 pm
---------------------------------------------------------
Any time that I need to remove a flywheel, I try a simpler
method first.
Over the years, I have found that you can loosen the flywheel
nut until it's flush with the crank threads.
With a helper, support the weight of the chainsaw by the
flywheel, and have your helper tap the flywheel nut.
If this doesn't work, look at the surface behind the flywheel,
determine if it's metal or plastic.
If it's plastic, find a suitable piece of flat metal to use as a
backup.
You can use a large flat blade screwdriver or a small crowfoot
for the next step.
Place the screwdriver beneath the flywheel, preferably under the
thick part of flywheel and the flat piece of metal, or case.
Twist or pry gently while TAPPING the flywheel nut with a small
hammer.
Caution and common sense must be used to avoid damage.
In most cases, the flywheel will pop free with two or three taps
but if not, you may have to use puller.
I am not necessarily recommending this procedure, just
describing the way I have done it for many years.

I agree. got so tired of pounding on the crank end (with nut
flush) and then having to either replace the nut or dress the
threads that I started looking for another method. happened to
spot my small pry bar and tried it under the flywheel while
tapping. voila, success. always shoot the shaft/flywheel
interface with kroil before even starting. not always necessary
probly but that's how a do it. even tough ones have come off
easily.

Yeah, that works most of the time, last summer I had stihl 360
pro that I suspected an air leak, two of us with a little
experience at this stuff could not get that flywheel off.
Finally took it to my dealer who had a puller, he gave that
puller quite a wack and it came off.
I found the air leak back there.

I have both but the 372.....and most current models are fine
thread. If I remember correctly, the 266 and some less
expensive Poulans are coarse. Regardless, they are not
expensive and work very well.

I use the hammer method on the end of the flywheel also. The
most stubborn flywheels I have come across so far have always
been on Dolmar saws that I have. It takes some time of prying
and tapping but eventually they all come loose.

I used a ball joint fork on a Stihl 440 once. Popped right off.

Were you able to get the fork wedged or did you use it as a pry
bar.

Wedged it,light tap and off she came. I was a
