Blade Servicing - Woods RM550 Operator's Manual

BELT REPLACEMENT
One of the major causes of belt failure is improper
installation. Before a new belt is installed, check
pulley shafts and bearings for wear. Check pulley
grooves for cleanliness. Make sure spindles turn
freely and without wobble. If grooves require clean-
ing, moisten a cloth with a non-flammable, non-toxic
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.
IMPORTANT
J 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.

Figure 8. Belt Routing
1. Disconnect idler spring from deck lug.
2. Slide belt under drive pulley "A" and over idler arm.
Position belt around drive pulley "A".
3. Loosen bolt holding belt guide "G" and swing it
away from pulley "B". Route belt around pulley "B",
idler "C" and pulley "D" as shown.
4. Make sure belt is on drive pulley "A", route around
idler "F", and connect idler spring to lug on deck.
5. Grasp belt between spindle pulley "E", spring-
loaded idler "F" and spindle pulley "D". Pull spring
loaded idler with belt to obtain enough belt length
to route it over pulley "C". Make sure spring-loaded
idler pivots freely with belt installed.
6. Adjust belt guide "G" to provide 1/16" to 1/8"
clearance from belt. Tighten bolt to 85 lbs.-ft.
