Not reverse threaded - normal right hand
threads. If there is any play at all in the arrangement you are using
to keep the shaft from turning - its going to be tough to loosen the bolt.
Normally, I have found a impact wrench will do it on the front bolt - but as I
said if you have any play in holding the pulley or if the pulley has any play on
the shaft (bolts a bit loose), it seems to ... ah hem ... lose its impact (pun
intended).
You say you don’t' have flywheel - then is there anything
you could clamp the counter weight retaining nut (the big one on the other end
of the engine) into that will prevent it from rotating?
I've never tried to remove the front bolt without
restraining the flywheel - but, there must be a way, perhaps one of the other
guys can be of some help.
Good luck.

Subject: [FlyRotary] E-Shaft Lock Bolt HELP!
I
am tearing down a 13B (1st time) and have spent the last few hours
trying to remove the eccentric shaft lock bolt. Is there some secret to it that someone
can share? I don’t have a flywheel
for the engine so I am holding the shaft with a pipe wrench on the pulley
boss. I have bent the handle on my
3/8 drive ratchet and couldn’t break it with a 24” breaker bar and a 5’
extension. I cranked-up my
compressor and couldn’t do it with my impact wrench. I tried turning clockwise to convince
myself that it isn’t reverse threaded. I would try heating but my torch won’t
stay lit for some reason (another thing to fix).
Does
anyone have a magic trick to get past this hurdle?
Is
there any reason that holding the pulley boss would prevent the lock bolt from
turning?
Any
and all suggestions are appreciated.
