Slide speed droop guide (75) with seal (77), assembled over end of rod (79) and thread into the
housing. Tighten securely.
Insert control spring pin (78) into hole at end of rod (79).
Assemble seal (74) to groove at end of guide (75) and install speed droop cap assembly (73) over
seal.
Install end plate (66), making sure that guide pin (69) enters the slot in the transfer pump liner (72). -
Install flat washers (65), Iockwashers (64), and screws (63) and torque to 25 to 30 inch-pounds.
Thread five full turns of spring (80) onto speed droop control rod (79). Slide the free end of the spring
over the formed ends of the governor arm (86) with the bent-in ends of the spring between the two
tabs.
NOTE
The apparent looseness in the governor parts is normal. Lost motion is immediately
taken up as soon as the pump actuates.
Assemble the throttle shaft assembly (26) with lever (35) installed partially into position through the
housing. Slide the spacer bushing (44) and the throttle shaft lever (45) over the throttle shaft so that
the projection on the throttle shaft lever bore engages the keyway on the shaft. Position the throttle
lever so that its forward tab straddles the linkage hook tab. Apply a light coat of grease to the throttle
and shut off seals (41 and 42). Assemble the shutoff shaft assembly (24) from the opposite side of
the housing with a slight rotary motion. Locate and secure shutoff cam (25).
Rotate the shaft until a click is heard. This is the governor arm (86) engaging the governor thrust
sleeve.
With the throttle shaft in the wide open position, check the clearance between the rear of the throttle
shaft (B) and the vertical tab (A) on the linkage hook. This clearance should be 0.210 to 0.225 inch.
(See figure 3-23.)
NOTE
Adjustment of this clearance is made by changing the effective length of the linkage
hook.
With adjusting screw (C) tight, apply pressure to tab (A). At the same time, rotate one or two
complete revolutions to assure that the linkage is in the full forward position. Loosen adjusting screw
(C) and slide the linkage to the full forward position. Insert linkage gauge No. 18914 between the
vertical tab (A) and the shutoff shaft (B). Slide the linkage hook until the face of the tab is flush
against the gauge. Tighten adjusting screw (C) and remove gauge. Check the adjustment and reset
if necessary.
Check all governor parts for freedom of movement.
Assemble frame assembly (16, figure 3-21), spring sleeve (14), spring (13) and arm assembly (15).
Adjust armature as illustrated in figure 3-24.
Install new insulating tubes (11 and 12, figure 3-21) and secure frame to cover (4) with insulating
washers (10), contact washers (9), and lock-nuts (8).
Install new gasket (6) to cover (4) and secure cover to pump with flat washers (3), lock-washers (2)
and screws (1).
