Section 5: Maintenance
WARNING
Before inspecting, cleaning or servicing the machine, shut off engine, wait for moving parts to stop, dis-
connect spark plug wire and move wire away from spark plug.
Failure to follow these instructions can result in serious personal injury or property damage.
A
Figure 5-7: Press down on point "A" to
remove or install belt.
1. Remove the belt cover. See
Removing the Belt Cover in this Section.
2. Press firmly downward on the cable
mounting bracket (A, Figure 5-7) until it
tilts and the belt slackens.
3. Remove belt (B, Figure 5-7) from
transaxle pulley.
4. Tip the mower onto its side (towards
the muffler) and pull the belt through the
cutout in the housing.
5. Do this step only if you did not
remove the mower blade — otherwise, go
onto step 6.
a. Make sure the spark plug wire is
removed from the spark plug and
moved away from the plug. Rotate the
blade so that one end is somewhere
within the front of the mower housing.
b. Work the belt around and over that
end of the blade (Figure 5-8).
c. Rotate the blade so that the other
end is somewhere within the front of
the mower housing and work the belt
around and off the mower.
d. Work the new belt around and over
the same end of the blade.
e. Rotate the blade so that the other
end of the blade is somewhere within
the front area of the mower housing
and work the new belt around and over
the same end.
6. Seat the new belt into the groove on
the engine pulley that is located on the
blade drive shaft.
7. Grasp one end of the new belt and
insert it in and through the cutout in the
housing.

blade.
8. Tip the mower back down to its
normal position.
9. Apply firm pressure against the cable
mounting bracket on the transaxle
assembly (A, Figure 5-7) until it tilts
forward.
10. Pull the belt over the transaxle pulley
and into the groove.
11. Release pressure on the transaxle
bracket slowly. Make sure that the belt
seats properly into the pulley groove.
12. Check the other end of the belt
(engine pulley) to insure that it is seated
properly into the groove.
13. Reinstall the belt cover. See
Replacing the Belt Cover in this Section.
ADJUSTING
WHEEL DRIVE CONTROL
Loss of wheel drive indicates that the
Wheel Drive Control may need adjust-
ment. This condition could also be the
result of not completely engaging a wheel
speed gear setting. Before you adjust the
wheel drive control cable, move the Wheel
Speed Control 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. Remove the belt cover (See Removing
and Replacing the Belt cover) and locate
the wheel drive clutch spring.
2. Measure the length of the body of the
wheel drive clutch spring (Figure 5-9).
Figure 5-9: First measurement with drive
clutch spring disengaged.
3. Engage the Wheel Drive Control Bail
and measure the extended length of the
spring body again (Figure 5-10).
Figure 5-10: Second measurement with
drive clutch spring engaged.
4. The difference between the 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, Figure 5-11) while
turning each adjuster (B, Figure 5-11)
away from the turnbuckle 1/2 turn each.
