5WPMAN0242 (Rev. 7/21/2008)
Use SAE 80W or 90W gear lube in the gearbox. Fill to
plug on side of gearbox.
Check gearbox daily for evidence of leakage at both
seals and the gasket between the housing and cover. If
leakage is noted, repair immediately. There may be a
small amount of lube emitted from the vent plug; this is
not considered leakage.
Overfilling the gearbox will cause the excess gear lube
to blow out vent plug and ruin the belt.
Driveshaft Lubrication
Lubricate the driveshaft slip joint every 8 operating
hours. Failure to maintain proper lubrication could
result in damage to U-joints, gearbox, and driveshaft.
1. Lower mower to ground.
2. Apply grease at the three locations as shown in
Figure 10.
3. Raise and lower mower several times to distribute
grease.

Belt Replacement
One of the major causes of belt failure is improper
installation. Before installing a new belt, check the fol-
lowing:
1. Check pulley shafts and bearings for wear.
2. Check pulley grooves for cleanliness.
3. Make sure spindles turn freely and without wobble.
If grooves require cleaning, 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.
Belt Installation
Refer to Figure 11.
NOTICE
■ 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.
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 E. Make sure spring-loaded idler pivots
freely with belt installed.
6. Adjust belt guide G to provide 1/16" to 1/8" clear-
ance from belt. Tighten bolt to 85 lbs-ft.
