Table 12-5 Stop 58 influence onto idle RPM
NOTE:
Adjusting the stop 58 based on propeller idle speed difference half, reduce the speed at idle of propeller
with higher RPM, and increase the speed at idle of propeller with lower RPM. This adjustment reduces
difference to minimum.
1 Remove securing of the stops 58, hold the screw with a wrench, use another to loose the securing
nut.
2 Turn the stop 58 on both governors according to value found in the table 12-5.
h) Verify for both governors the dimension „B“, which changes (
±
) 0,35 mm (0,014 inch) when half a turn
is used and (
±
) 0,7 mm (0,028 inch) when 1 turn is used. If you will find a deviation, adjust the
dimension "B" to the calculated value. For fine adjustment use 1/3 or 1/4 turn of the stop 58 .
CAUTION:
TURNING WITH THE STOP 58 FOR MORE THAN
±
1 TURN IS NOT PERMITTED.
i) Hold the screw in adjusted position with suitable wrench, use the second wrench to tighten the securing
nut and again verify the dimension "B" for both governors.
j) This adjustment of the stop 58 disturbs alignment of guideline on the cam lever with the governor
scale.
k) Change lever 29 length (figure 12-33).
l) Remove lock wire from both nuts (nuts with left and right thread, the nut with left thread is marked with
letter "L") from the rod 29 and adjust its length with turning such way, that alignment is rearranged.
Press the lever "Bc" in direction of the arrow whole mechanism to the stop 58.
m) Then tighten the nuts and verify again the alignment of guidelines. Safety both nuts with wire.
