TABLE 9-5.1. TRANSMISSION SHIFT CONTROL AND LINKAGE ADJUSTMENT (FIGURE 9-47)
PRELIMINARY STEPS
A.
Open engine exhaust grilles and remove engine access cover (Figure 9-3, step 3 through 5). Place wooden
block approximately 2-1/2 inches thick on engine step plate under grille support. If access to bulkhead is
required, also remove intake grille (Fig. 9-3, step 1).
B.
C.
Remove two screws, washers and protective plate from transmission control cable support (Figure 9-4, item 12).
D.
TRANSMISSION SHIFT CONTROL ADJUSTMENT
1.
At transmission, remove cotter pin and clevis pin and disconnect shift linkage from shift lever.
2.
Move driver's shift control to any drive range then back to "N" (NEUTRAL) position.
3.
Align hole in driver's shift control with hole in pad on shift quadrant. Insert a 1/8-inch dia. pin in hole provided to
4.
Adjust late design control assembly by using jam nuts at mounting bracket in driver's compartment, to obtain
measurement of 1/8 41/16 inch from control cable tube to clevis jam nut.
4A.
Adjust early design control assembly by using jam nuts at mounting bracket in driver's compartment to obtain a
measurement of 2 inches from control assembly wiper-seal to threads on race rod.
5.
Move shift lever on transmission (by hand) to "N" (NEUTRAL) position as indicated by selector indicator on
transmission.
6.
At transmission control support bracket, adjust control assembly jam nuts to provide a free pin fit at transmission
shift lever.
7.
Remove 1/8-inch dia. pin from quadrant, operate driver's shift control in all positions and check for proper
synchronization between driver's and transmission shift levers (clevis pin at transmission shift lever should fit
freely in all shift positions). (Replace cotter pin).
NEUTRAL SAFETY SWITCH ADJUSTMENT
8.
Perform step 3,
9.
Loosen two neutral safety switch mounting screws.
10.
Position switch so that roller is in center of heel of lever and is depressed sufficiently to actuate switch (switch
closed). Tighten mounting screws.
11.
Remove 1/8-inch dia, pin, set parking brake and start engine to check proper operation of switch. Attempt to start
engine with driver's shift control in other than "N" (NEUTRAL) position. If switch is adjusted correctly the engine
starter will not activate.
