12-159
Pressure gage should read 75 to 77 psi (517 to 531 kPa). If pressure is within this range
proceed to Sub Para b. or c. of Height Control Adjustment. If not, continue with Step (10).
(10)
To adjust pressure regulator (11) remove cap (12) on regulator and turn adjustment screw (13) left to
increase pressure, right to decrease pressure. Pressure should be 75 to 77 psi (517 to 531 kPa).
b.
Height Control Adjustment (Right Side).
(1)
Start engine and build air pressure to 110 psi (758 kPa).
(2)
Loosen low pressure limit capscrew (1) and adjust load sensing valve (2) until the air pressure gage
connected to air tank No. 4 (3) reads 31 psi (214 kPa) 2 psi ( 14 kPa).
(3)
Rotate low pressure stop (4) until tab on the stop touches the control shaft cross pin (5). Tighten
capscrew (1) to 72 to 84 lb-in (8 to 9 N.m).
