ADJUSTING
WHEELDRIVECONTROL
Loss of wheel drive indicates that the
Wheel Drive Control may needadjust-
ment. This condition could also be the
result of not completely engaginga wheel
speed gear setting. Beforeyou adjust the
wheel drive control cable, move the Wheel
SpeedControl Lever to 1 (all the way
back) or to 3 (all the way forward). If the
wheels still do not engage, adjust the
wheel drive clutch spring.
1. Removethe beltcover (SeeRemoving
and Replacing theBelt cover) and locate
the wheel drive clutch spring.
2. Measurethe length of the body of the
wheel drive clutch spring (Figure 5-9).

clutchspringdisengaged.
3. Engagethe Wheel DriveControl Bail
and measurethe extendedlength of the
spring body again (Figure 5-10).

4. The difference betweenthe two mea-
surements should be approximately 1/4".
Adjust if the result does not meet this
specification. Spring extension is
adjusted with a cable adjuster (R, Figure
3-1) on the wheel drive cable. To adjust,
hold the turnbuckle (A, Figure5-11) while
turning each adjuster (B, Figure5-11)
awayfrom the turnbuckle 1/2 turn each.
