age will insure that the operator’s steer con-

trol will have full and equal travel for right

and left steer.

(2) The steer valve body assembly in-

cludes a detent arrangement which seats only

when the steer valve is in the No Steer posi-

tion. The operator’s control wheel (or T bar)

must be in a central, or No Steer position, at

that time. Adjust the linkage so that it can be

connected with the control and valve in the No

Steer position.

Check to see that full travel

for right and left steer can be obtained.

e . Throttle Valve Linkage. To obtai n

maximum performance and fuel economy, the

throttle valve linkage must be properly ad-

justed. The throttle lever moves 17° 48' from

a closed-throttle position to full-throttle posi-

tion. A positive stop, located in the selector

valve

body,

indicates

a

full-throttle

valve

travel (fig. 372, fold-out 1). To properly ad-

just the throttle linkage, proceed as follows:

(1) With the rod end disconnected at the

throttle valve lever, rotate the throttle valve

lever clockwise until rotation is stopped. (An

internal machined stop is provided in the valve

body. )

(2) While holding the throttle valve lever

at full clockwise rotation, move the engine

throttle linkage to the full-throttle position

(engine governor).

(3) Adjust linkage to provide full rota-

tion of the throttle valve lever at full-engine

throttle by alining the hole in the rod end with

the hole in the throttle valve lever.

(4) Prior to connecting the linkage check

to insure:

(a ) That full-engine throttle is obtain-

ed. (Additional travel should be available by

utilizing the throttle control yield link.)

(b ) That the throttle valve lever will

allow the linkage to return to the closed-throt-

tle position.

(5) Connect linkage.
