d) When properly tensioned, the alternator belt will deflect 3/8"-1/2" (9-13 mm)
while applying 22 pounds of force to the belt midway between fan and
alternator.
Belt Guide Adjustment.
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Remove the belt shield on the right side of mower deck.
c) Locate belt guide bolted to deck near the shield support stud and right-hand
pulley. Guide should be 1/8" (3 mm) away from the belt, with bolt-end of
guide near end of slot (See Figure 12).
d) If adjustment is necessary, loosen the bolt securing the belt guide and
make proper adjustment. Tighten hardware.
BELT GUIDE POSITIONING
Brake Link Adjustment.
Check to make sure brake is adjusted properly.
a) Disengage brake lever (lever down).
b) Measure the length of the spring. Measurement should be 2.75" (7 cm)
(See Figure 13).
c) If adjustment is necessary, adjust the nyloc nut at the bottom of the spring to
achieve 2 3/4" (7 cm).
d) Engage the brake lever (lever up).
e) The space between the brake spring bracket and the nyloc nut under the
spring should measure 3/16" to 1/4" (4.8 – 6.4 mm).
f) If adjustment is necessary, loosen jam nut above the trunion roller. Adjust
the nyloc nut under the trunion roller until 3/16" to 1/4" (4.8 – 6.4 mm) exists
between the spring retainer bracket and the adjacent nyloc nut. Tighten the
jam nut above the trunion roller.
g) If a 3/16" to 1/4" (4.8 – 6.4 mm) gap can no longer be achieved because there
is no clearance between nyloc nut below the spring and the jam nut above the
trunion or there are no threads left on the bottom nyloc nut, the length of the
brake rod can be adjusted. Remove a pin from a yoke at either end of the
brake rod and lengthen (or shorten) the brake rod until 3/16" to 1/4" (4.8 – 6.4
cm) gap can be achieved by following steps e) and f).
