(a) Identify a dimension required to space the clamp
assembly and valve assembly apart and reestablish
positive clearance.
(b) Increase the thickness of the reverse stop with the
dimension required to reestablish positive clearance
between the clamp assembly and the valve assembly.

thicknesses.
2 Select a single stop with the required thickness.
(c) Remove the nuts and washers, if applicable, from the
ends of the three push rods protruding from the jack
assembly.
NOTE: Keep the nuts and washers with the
propeller and jack assembly.

the push rods and sleeve toward the engine are far as
they will travel.
(e) Loosen and unthread the hub nut from the engine
shaft.
NOTE: This will pull the propeller away from the
engine and allow the push rods and sleeves
to slide out of the guide collar on the engine
side of the guide collar.
(f) Allow the jack assembly push rods to completely slide
out of the guide collar.
(g) Turn the jack plate unit until the pitch change forks
disengage from the pitch change blocks.

thickness onto hub.
(i) Position the jack plate unit and the hub to engage the
pitch change blocks.
