4.2.10 Electric Clutch Adjustment:
4.2.11 Reverse Indicator Adjustment:
Brake Link Adjustment:
Check to make sure brake is adjusted properly.
a) Disengage brake lever (lever down).
b) Measure the length of the spring. Measurement should be 2.75" (7.0 cm)
between washers (see Figure 11).
c) If adjustment is necessary, tighten the nut directly below the yoke and
loosen the bottom nut (bottom one of the two tightened together) below the
spring. Turn the nut directly below the washer (top nut of the two tightened
together) until the correct measurement is obtained. Tighten the two nuts
together and repeat on opposite side of unit. Turn clockwise to shorten
spring length and turn counter-clockwise to lengthen the spring.
Brake Adjustment:
a) Check for brake link 2.75" (7.0 cm) measurement as described in section 4.2.8.
b) Engage brake lever (lever up).
c) Measure the distance between the trunion roller and the rod collar.
Measurement should be 1/4" (6.4 mm) to 5/16" (7.9 mm). See Figure 11.
d) If adjustment is necessary, loosen the nut directly below the yoke. Turn the
bottom nut (below washer) until the correct measurement is obtained (See
Figure 14) turn nut clockwise to lengthen the gap (screws rod into yoke) and
turn counter-clockwise to shorten the gap (screws rod out of yoke). Tighten
nut against yoke and check opposite side of unit, repeat if necessary.
No adjustment necessary.
a) Stop engine, wait for all moving parts to stop, and remove key. Engage
parking brake.
b) Unhook seat latch and tilt seat forward.
c) Begin with either the left or right motion control lever. Move lever to the
neutral position and pull lever back until the clevis pin (on arm below pivot
shaft) contacts the end of the slot (just beginning to put pressure on
spring), See Figure 13.
d) Check where lever is relative to notch in console (should be centered
allowing lever to pivot outward to the neutral lock position).
e) If adjustment is needed, loosen the nut against the yoke and while applying
slight rearward pressure on the motion control lever, turn the head of the
adjustment bolt in the appropriate direction until lever is centered (keeping
rearward pressure on the lever will keep the pin at the end of the slot and
allow the adjustment bolt to move the lever to the appropriate position).
Tighten lock nut.
