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.

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
b o d y . )
(2) While holding the throttle valve lever

(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.
