3. 44" Models Only:Loosen the jam nut (M) on the eye
bolt (N) and then loosen the adjustment nut (O) to relieve
the majority of the tension exerted on the belt from the
idler arm.
WARNING
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.
4. Using a 1/2" breaker bar (B, Figures53&54) place the
square end in the opening in the idler arm (C) and rotate
the idler armclockwise, which will relieve tension on the
belt exerted from the idler arm. Remove the belt from the
left hand side spindle pulley (D). Pull the length of the belt
removed from the left hand spindle pulley towards the
center of the deck.
5. Rotate the idler armclockwiseso that it is pulled away
from the idler arm stop (L). To remove the belt from the
belt guide (E), start with the leg of the belt between the
adjustable idler pulley (F) and the PTO clutch pulley (G)
and press the belt down below the belt guide and then
pull it around and then above the belt guide. Carefully
release the tension on the breaker bar.
6. Remove the old belt from the front stationary idler pulley
(H), rear stationary idler pulley (I), and the remaining
spindle pulleys (J).
7. Install the new belt onto the right hand side and the
center spindle pulleys (J) and the PTO clutch pulley (G).
Make sure that the V-side of the belt runs in the pulley
grooves and that the belt is correctly routed through the
PTO clutch belt guide (K) and that the back side of the
belt contacts the faces of the front stationary idler pulley
(H) and the rear stationary idler pulley (I).
8. Rotate the idler armclockwiseso that it is pulled away
from the idler arm stop. To install the belt into the belt
guide, start with the leg of the belt between the adjustable
idler pulley and the PTO clutch pulley and raise the belt
up into the belt guide. Pull the length of belt towards the
left hand spindle pulley. Carefully release the tension on
the breaker bar.
9. Verify that the V-side of the belt runs in the grooves of
the right hand side and center spindle pulleys and the
PTO clutch pulley. Verify that the back side of the pulley
contacts the face of the adjustable idler pulley, front
stationary idler pulley, and the rear stationary idler pulley.
Verify that the belt is correctly routed through the belt
guides.
10. Rotate the idler armclockwiseand install the belt on the
left hand spindle pulley.
11. Carefully release the tension on the breaker bar.
12. Set the mower deck to the 3-1/2" (8,9 cm) cutting height.
13. Use the Spring Length chart to determine the correct
spring length for your unit.
