Paul,  this rear counterweight does not appear in Haynes or on
Bruce's
video.  I assume it was added when the manual flywheel was removed.
Is
that standard practice?   Do I use a puller to remove it?    I am
the
third owner of this engine since it was dedicated for aircraft use.
 I
believe the first owner rebuilt it.  This is my first time inside
this
or any rotary.  Thus far it has been good news.  New oil pump and
chain
and all new bolts and is  immaculately clean except for surface
discoloration on the counterweights.   Jerry

Smack it with a hammer and it will pop right off the taper. I see you
got
the hard part done. The big nut is off:)

I spent the last two hours trying to get the counterweight to release.
I've tried hammering as hard as I am willing to go.  Nothing.   I made
a puller using 1/2" all thread for the center post with a nut welded
on
one end.   Probably the welding annealed the all thread because I
twisted the end off of it.  Before the all thread gave way,  I was
pulling about as hard as I could on  the 1/2 rachet.  but I had not
yet
gone to the 22 inch breaker. During breaks from the above activity,  I
went through all the pry bars  I own except for the 36" crow bar.   If
someone knows how to do this, please let me know.    Thanks,  Jerry

p.s.  Do any of  you sharp rotary mechanics live near Northern
Indiana?


What size hammer did you use? Try a ten pound sledge. did you put some
WD40
on there?

I got it off no problem at all once I started to think for myself.
The flywheel bolt holes were threaded all the way through so I was able
to jack the counterweight off the shaft by just running  a few bolts.
Took about a minute.    The engine is fully apart now and looks good.
Assembly grease on every surface.  I will clean it up tomorrow.    Jerry


Now the thrust bearing is shot. Just kidding :)
