a. Tighten the screw/rod up to abutment while counting with attention the
number of groove intervals it rotates to come into abutment (and therefore
how many half degrees the propeller pitch has changed). Write down this
variation.
b. Remove the screw/rod and read the number stamped on it.
c. If the screw/rod is the one intended to adjust the forward motion pitch, the
so-founded aforesaid pitch variation must be detracted from the value of
the pitch stamped on such screw/rod , on the contrary, if the screw/rod
is the one intended to adjust the backwards motion pitch, the so-founded
aforesaid pitch variation must be added to the value of the pitch stamped on
such screw/rod.
PRACTICAL EXAMPLE CONCERNING
THE FORWARD MOTION PITCH
To reach the abutment position the forward pitch adjustment screw
/rod has rotated of 5 intervals, that is the forward motion pitch has
increased of 2,5 degrees ( 5 x 05 = 2,5). The number stamped on
the screw/rod is 22 (corresponding to a forward motion pitch of 22
degrees). The propeller forward pitch was therefore set at 19.5
degrees (22 – 2,5 = 19,5).
PRACTICAL EXAMPLE CONCERNING
THE BACKWARDS MOTION PITCH
To reach the abutment position the backwards pitch adjustment screw
/rod has rotated of 5 intervals, that is the backwards motion pitch
has decreased by 2,5 degrees ( 5 x 05 = 2,5). The number stamped
on the screw/rod is 1 (corresponding to a backwards motion pitch of
16 degrees). The propeller backwards pitch was therefore set at 18.5
degrees (16 + 2,5 = 18,5).
