LINKAGE ADJUSTMENT
N O T E : Key numbers in text refer to figure 1.
1. Place transmission selector and shift levers
(9) in " N E U T R A L " position.
2. Adjust selector and shift rods (8) to provide
90° angularity at the lower end of the gearshift
lever (1) to the control island panel (2) as shown.
N O T E : On Model TM-80 with Clark 387V
transmission the angularity between the gearshift
lever (1) and control island panel (2) after adjust­
ment should be 98° 30'.
Adjustment is accomplished by rotating the
adjustable clevis (see Inset, fig. 1) at either the
control island or transmission end of the selector
and shift rods (8). Tighten lock nuts securely.
3. Check adjustment by moving gearshift lever
through the shift pattern. There must be no binding
in the linkage.
N O T E : At the extreme selector and shift move­
ments, clevis pins should rotate freely. Readjust
linkage, if necessary, to obtain these conditions.
4. Replace any worn or damaged cotter pins.
5. Lubricate control linkage as described in
LU BR IC ATION (SEC. 0) of this manual.
