3. Using a 5 mm internal hex wrench for the neutral
adjusting shaft or a 3 mm or 4 mm internal hex
wrench for the neutral adjusting screw, rotate clock-
wise until the pressure increases in one of the
pressure gauges. Note the angular position of the
wrench. Then rotate the neutral adjusting shaft or
screw counterclockwise until the pressure increases
by an equal amount on the other gauge. Again note
the angular position of the wrench.
4. Rotate the neutral shaft or adjusting screw clockwise
half the distance between the locations noted above.
The gauges should read the same pressure (case
pressure), indicating that the control is in its “neutral”
position.
5. Hold the neutral adjusting shaft or screw stationary.
Tighten the neutral shaft lock nut (early production
controls) to 22 Nm (195 lbf•in.). Tighten the neutral
adjusting screw lock nut (later production controls) to
7 Nm (62 lbf•in.) for the 6 mm screw or 13.5 Nm
(120 lbf•in.) for the 8 mm screw.
Do not overtorque
the nut.
6. Once the neutral position is set, stop the prime
mover, remove the gauges, and install the gauge
port plugs. Reconnect the external control input.
