Friction-torque check?

The ROTAX rep advised me awhile back that the friction torque check was unintentionally omitted from the 100-hour list.  It is still a 100-hour item.  This check will be included in their next MM update.

Good observation.

i have deeply study the 100 hrs maintenance manual of old and new book. nothing vale found in specific sheet.

another chapter  12-00-00 sub article  (17.1) Propeller gearbox,  this is the value 

The friction torque must be between 30 Nm and max. 60 Nm (22 to 44.3 ft.lb).

procedure is as

I have diffulty with searching this site.  Some of the answers are way too old. 13y. in top result?????

The manual says "With the crankshaft locked, the propeller can be turned by hand 15 or 30
degrees depending on the profile of the dog gears installed.
This is the maximum amount of movement allowed by the dog gears in the
torsional shock absorption unit."

I have never seen this addressed.  the 15 OR 30°. ?????  How do I know the profile of my dog gears???

Man O Man does Rotax need lessons from Honda for manual construction!!

"Attach a calibrated spring scale to the propeller in distance (L) from the center
of the propeller. Measure the force required to pull the propeller through
the 15 or 30 degree range of free rotation."

Does this mean that the prop is "pulled over" the gear and scale drops to 0 after it "pops over"?

On another thread - "You can measure any where from 24 - 30 inches out from the center of the prop hub. Put your handy dandy fish scale on that mark and make a nice steady pull until the prop stops noting all the time what the lbs. reading on the scale as you pull."

I am old now but my memory is not completely gone.

Never in my life, while pulling  a scale and having the item being pulled come to a "stop", has the scale not continued to rise to a level that I can no longer pull or the scale is overloaded.

Something in the definition of "until the prop stops" has to be spoon fed to me.

I sincerely apologize in advance of my apparent near total ignorance of common English.
