MACHINE SETUP AND CALIBRATION
Measure Blade Leading Edge Height
1. Fully pitch machine by pressing and holding Twin pitch
up button until pitch cylinders fully extended.
2. Choose a blade on both LH and RH Rotor. Using Gauge
P/N 32044, measure height of raised leading edge
ensuring it is 2.00” ±.060” (Figure 37). If the blade slides
under the first step but not the next, it is within limits.
Figure 37. Measuring Leading Edge Height
Leading Edge Height Adjustment
1. If leading edge height is within limits (2.000” ± .060”)
for left and right side, then no adjustment is needed.
Otherwise, proceed to next step for adjustment.
2. Flatten blades (bottom out the pitch cylinders).
3. Remove clevis pin (Item E, Figure 38). Loosen jamb
nuts (Item C, Figure 38) and adjust clevis (Item D,
Figure 38) to cylinder (Item A, Figure 38) position, to
raise or lower pitch as required.
