Replace Belt
■ Use care when installing or removing belt
from spring-loaded idler at step 5. Springs store
energy when extended and, if released suddenly,
can cause personal injury.
One of the major causes of belt failure is improper
installation. Before installing a new belt, check pulley
shafts and bearings for wear. Check pulley grooves
for dirt. Make sure spindles turn freely and without
wobble.
If grooves require cleaning, moisten a cloth with a
non-flammable, non-toxic degreasing agent or com-
mercial 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.
1. Loosen bolt holding belt guide A and swing it
away from pulley B.
2. Pass a loop of belt underneath front of gearbox
stand ahead of gearbox pulley C. Use care not to
over-bend belt as bending can cause internal dam-
age.
3. Route belt over pulley D.
4. Route belt around gearbox pulley C and route a
loop underneath rear of gearbox stand.
5. Use a 1-1/4" open end wrench to rotate idler arm
E counter-clockwise enough to install belt around idler
pulley F.
6. Route belt around spindle pulley "G" and idler pul-
ley H.
7. Grasp remaining belt loop with both hands and
pull the spring-loaded idler enough to route belt over
spindle pulley B. Make sure spring-loaded idler E piv-
ots freely with belt installed.
8. Adjust belt guide A to provide 1/16 to 1/8" clear-
ance from belt. Torque bolt to 85 lbs.-ft.
