d. Reassembly (fig. 46).
(1) Slip a new O ring (5) into the groove around the inside of the slowdown body (8), and insert the plunger (4)
down into place.
(2) Assemble the plunger pin (3) into the adjusting screw (1) and screw the adjusting screw into the slowdown
body.
(3) Install the elbow (7) and shutoff cock (6).
e. Installation (fig. 41).
(1) Screw the tube tee (17), with elbows (19 and 23) and drain cock (18) attached, into the slowdown body.
(2) Fasten the slowdown assembly to the crankcase cover with the two hex head bolts (24) and lockwashers
(21). The slowdown plunger pin must engage the lower end of the governor lever.
(3) Connect the tube assembly (25) to the elbow (23).
f. Slowdown Stroke Adjustment. The slowdown assembly should not be adjusted unless the engine does not return
to idle speed when the compressor unloads. Lengthen the slowdown stroke, to further reduce engine speed, by loosening
the locking nut (2, fig. 46) and turning out the stroke adjusting screw (1). Tighten the locking nut. Check operation. If the
engine still runs too fast with an unloaded compressor, turn the stroke adjusting nut out further. To increase the engine
speed while the compressor is unloaded, reverse the above procedure.
110. Governor
a. Removal (fig. 47).
(1) Remove the hex nut (4) and lockwasher (3) and disassemble the control rod (2) from the upper end of the
governor lever.
(2) Remove the hex nuts (7) and lockwashers (6) from the governor mounting studs, and carefully lift the
governor (1) and mounting gasket (5) from the crankcase cover.
b. Installation (fig. 47).
(1) Position the gasket (5) around the governor mounting opening, and carefully install the governor (1),
meshing the governor gear with the accessory governor drive gear. Install the hex nuts (7) and lockwashers
(6).
(2) Connect the control rod (2) to the upper end of the governor lever and install the hex nut (4) and lockwasher
(3).
