[R-390] PTO friction ?

[Pete Williams]

G'day all..from my experience,over both Cosmos  and Collins PTO some
friction/resistance to rotation is inevitable ---- question is one of
relativity.   Those who can 'freely' turn the kHz knob with one  finger have
hitherto undisclosed digital muscle  development in my view, or definition
of 'freely'somewhat elastic!

The lead screw and sliding restraint have non negligible resistance.. It
would be better if there was a turning torque stated as so many inch- ozs.
to a pull point on the spigot that connects to the Oldham coupler.

Anyone got or want to quote a figure ?
