CAUTION:
MAKE SURE THAT THE SCREWS DO NOT
EXTEND MORE THAN THREE THREADS
PAST THE BULKHEAD NUTPLATES. IF THE
SCREWS EXTEND MORE THAN THREE
THREADS, THIS CAN CAUSE DAMAGE TO
THE AIRCRAFT COWLING.
(6) Attach the spinner dome to the spinner bulkhead with the
supplied screws and washers. Refer to Table 3-3.
(a) Install a screw in the hole(s) centered between each
two adjacent blade cutouts.

cutouts does not align with a mounting hole,
install screws in the two holes closest to the
centerline.
CAUTION:
BE SURE THE SCREWS DRAW THE
SPINNER DOME TIGHT TO THE
BULKHEAD.
(b) Tighten the screws until snug, then turn an additional
1/8 rotation to achieve an approximate torque value
of 20-30 In-Lbs. (2.3-3.3 N•m).
CAUTION:
IN THE FOLLOWING STEP, TIGHTEN
EACH SCREW BEFORE INSTALLING
THE NEXT SCREW.
(c) Working from the screw(s) previously installed at
the centerline toward the blade cutouts, install the
remaining screws.
1 Tighten each screw until snug, then turn an
additional 1/8 rotation to achieve an approximate
torque value of 20-30 In-Lbs. (2.3-3.3 N•m)
before installing the next screw.
(7) Install the lock nut “B” on the low pitch stop with the step
facing the cylinder as shown in Figure 3-19.
