BELT SERVICING
Inspect Belt
One of the major causes of belt failure is improp-
er installation. Before installing a new belt, check the
following:
1. Remove thumb screws and remove belt shields. Set
shields aside. Replace thumb screws on studs to
prevent loss.
2. Check spindle shafts and bearings for wear.
Spindles should not have endplay.
3. Check pulley grooves for cleanliness. If grooves
require cleaning, moisten a cloth with a nonam-
mable, non toxic degreasing agent or commercial
detergent and water.
4. Make sure spindles turn freely and without pulley or
blade wobble.
If grooves require cleaning, moisten a cloth with a non
ammable, nontoxic degreasing agent or commercial
detergent and water.
Avoid excessive force during installation. Do not use
tools to pry belt into pulley groove. Do not roll belt over
pulleys to install. This can cause hidden damage and
premature belt failure.
Remove Belt
■ Use care when installing or removing belt from
spring-loaded idler. Springs store energy when
extended and, if released suddenly, can cause
personal injury.
IMPORTANT: Avoid excessive force during installa-
tion. Do not use tools to pry belt into pulley groove.
Do not roll belt over pulleys to install. This can
cause hidden damage and premature belt failure
1. Grasp belt between spindle sheave E, spring- load-
ed idler F, and spindle sheave D. Pull spring- loaded
idler with belt to obtain enough belt length to route
it over sheave E.
2. Check that spring-loaded idler pivots freely. Clean
and lubricate if necessary.
3. Loosen gearbox mounting bolts, but do not remove.
This will ensure the belt can be slid under gearbox
shaft without pinching or cutting.”
4. Remove belt from remaining sheave grooves and
then from mower. Inspect belt for damage. A belt
that will not lay at on the ground indicates broken
cords.
Install Belt
■ Use care when installing or removing belt from
spring-loaded idler. Springs store energy when
extended and, if released suddenly, can cause
personal injury.
1. Route belt around spindle sheave B, backside idler
C, and spindle sheave D as shown in Figure 17.
2. Slide belt under drive sheave A and over spring-
loaded backside idler F. Position belt in drive sheave
grooves, except for spindle sheave E.
3. Grasp belt between spindle sheave E, spring- load-
ed idler F, and spindle sheave D. Pull spring- loaded
idler with belt to obtain enough belt length to route
it over sheave E.
4. Tighten gearbox mounting bolts and torque to 170
ft-lbs.
5. Remove thumb screws from studs. Replace belt
shields. Ensure tabs on end shields are tted into
slots in deck rails. Thumb screws to be secured
tightly to prevent loss.
