Check Deck Drive Belt
1. Make sure the V-side of the belt runs in the pulley
grooves (
Figure 19
).
2. If belt is not properly seated, use a 1/2” breaker bar, and
place the square end in the square hole located in the
end of the idler arm (
A, Figures 20
). Carefully rotate the
breaker bar COUNTER-CLOCKWISE, which will relieve
the tension on the belt exerted from the idler arm and
spring.
3. Re-seat belt and carefully release the tension on the
breaker bar.
WARNING
Spring loaded components can kick back
causing injuries.
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring
as the idler arm is being rotated. Injury may result if the
breaker bar is prematurely released while the spring is
under tension.
NOTICE
To avoid damaging belts, do NOT pry belts over pulleys.
