Yep The Safari uses a centrifugal clutch with shoes and clutch linning.
Invariably some dirt(I fly in the Mojave desert) and oil can accumulate in
the clutch making it get a bit sticky. This is especially true if the owner
is not careful with the transmission oil drain or transmission chip detector
installation(I'm learning to be more careful). The ONLY belt on the Safari
drives the alternator. Not counting the seatbelts.

Now I have to ask what type of clutch mechanism is being used.
Everything I have seen under the covers, R22, helicycle, Rotorway, all
use a belt tensioning clutch. Does the sadari use something else?

During pre-flight, I turn the main rotor backwards. If the clutch is
dragging it tries to turn the engine also. In this case the Clutch was
getting sticky requiring the starter to turn both the engine and the
rotor.
Normally just a little brake cleaner followed with a drop or two of
engine
oil does the trick. But no..I was in a hurry. Starter began cranking
and
then a crack was heard and the starter when ballistic.
