PAR 234 TESTS AND ADJUSTMENTS CHAP 5, SEC XXXIV 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 obtain 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. 201
