Maintenance
5. Loosen but do not remove the hardware that
secures the stationary idler pulley (
B
) and the
adjustable idler pulley (
E
). This will allow the
pulleys to be tipped up away from the belt keeps so
the belt can be removed.
6. Loosen the hardware that secures the belt keep by
the blower pulley (
C
) and rotate the belt keep out of
the way.
7. Remove the old belt and replace with a new one
(
A
). The flat side of the belt (colored black) must
contact the flat side of the stationary idler pulley
and the V-side of the belt (colored gray) must
contact the the V-goove of the blower pulley and
the adjustable idler pulley.
8. Position the stationary idler pulley belt keep (
A,
Figure 60
) so that right side of the belt keep is
parallel to the bend in the idler plate (
identified as
“1”,
Figure 61
) and then tighten the stationary idler
belt keep hardware (
B
) to secure it in place.
This positioning is necessary to prevent accidental
contact between the stationary belt keep and the
adjustable idler pulley during operation.
9. Position the adjustable idler pulley belt keep (
C
) so
that the face of the belt keep is parallel to the face
of the idler arm bracket (
identified as “2”,
Figure
61
) and tighten the adjustable idler pulley belt keep
hardware to secure it in place.
10. Position the blower pulley belt keep (
A,
Figure
62
) as close to the blower pulley (
B
) as possible
without contacting it and the tighten the blower
pulley belt keep hardware (
C
) to secure it in place.
11. Push on the adjustabler idler pulley belt keep (
A,
Figure 61
) to move the adjustable idler pulley
towards the stationary idler pulley (
B
) and install
the bel on the mower deck double pulley (
D,
Figure 60
). The V-side of the belt (colored gray)
must contact the V-groove of the pulley. Carefully
release the tension you are exerting on the
adjustable idler pulley belt keep.
