5. Remove the spring anchor hardware (D) that anchors the
idler arm spring (E) to the mower deck.
6. Remove the old short right hand belt (F) from the front
idler pulley (G) and the center spindle pulley (H).
7. Install the new short right hand belt onto the center
spindle pulley and the front idler pulley.
8. Re-connect the idler arm spring. Install the 3/8 washer
and then the spacer onto the shaft of the 3/8 bolt. Install
the hook of the idler arm spring around the body of the
spacer and then install the bolt into the spring anchor tab
and then secure with the 3/8 nylock flange nut.
9. Rotate the spindle drive idler arm clockwise, which will
relieve tension on the belt exerted from the idler arm. Re-
install the belt on the right hand spindle pulley and then
the rear idler pulley. Make sure that the V-side of the belt
runs in grooves of all four pulleys. Carefully release the
tension on the spindle drive idler arm.
10. Set the mower deck to the 3-1/2" (8,9 cm) cutting
position.
11. Measure the coil-to-coil length (I) of the idler arm spring.
The measurement should equal 6-1/8" (15,6 cm) ± 1/8
(0,32 cm). If not, loosen the jam nut (J) on the carriage
bolt (K) and the 3/8" nut (L) that secures the rear idler
pulley (B) to the deck. This will allow the rear idler pulley
to move in it's adjustment slot.
12. Turn the adjustment nut (M) until the measurement
is achieved. Tighten the jam nut and the 3/8" nut that
secures the rear idler pulley to the deck.
13. Re-install the long left hand deck belt. See Long
Left Hand Deck Belt Replacement for re-installation
instructions.
14. Re-install the mower deck guards and the floor pan.
15. Run the mower under no-load condition for about five (5)
minutes to break in the new belts.
