## Discrepancy

THESE MCCAULEY PROPELLERS COME PLACARDED TO LUBE TORQUE TO 40-45 FEET/POUNDS.  THE CESSNA MM SPECIFIES 80-85 FEET/POUNDS DRY TORQUE.  THE CESSNA TECH SAID BOTH ARE ACCEPTABLE, BUT DO NOT MIX THE TWO.  TECH SAID 80 POUNDS LUBE TORQUE WILL PULL THE STUD OUT OF THE HUB.  THIS COULD BE CONFUSING, AND HAS CAUSED EXPENSIVE PROBLEMS.
