'Can someone who has responded to this subject explain to me their
reluctance to removing a prop? Is it because they have an Aeromatic?
I too dreaded removing my prop (Ranger W/ Warner hub+ Sensennich
86AB54)...until I noticed some "smoking" at hub/prop junction. Upon
removal, it was discovered (not related to original reason for
removal) that the rear cone was in the advanced stages of galling.
Nearly threatening the hub's integrity. Hub was not loose nor was
nut. I found it no issue to remove prop/hub assemby and made it a
personal inspection point at every other annual. I wouldn't think it
is a "set it and forget it" Ronco cooker. Probably because the
short splined Warner and Rangers use no front cone and if the forward
bronze bushing is worn the hub can walk around (galling the rear
cone) without experiencing a loss of nut torque. Having witnessed
this, if I was McLucky's mechanic and I never saw that prop off, I
would be inclined to remove it as well.
As for finding the "crank time", it has never failed to be spot on
and repeatable to use a dead stop through a plug hole to find BDC and
set the degree wheel accordingly.
