of the center spindle pulley and the PTO clutch pulley.
Make sure that the back side of the belt contacts the face
of the adjustable idler pulley. Make sure that the belt is
correctly routed in the belt guides (F & I).
9. Using a 1/2" breaker bar place the square end in the
opening in the PTO clutch drive idler arm and rotate the
idler arm clockwise, which will relieve tension on the belt
exerted from the idler arm. Install the long left hand belt
onto the left hand spindle pulley. Carefully release the
tension on the breaker bar.
10. Measure the coil-to-coil length (A, Figure 65) of the long
left hand belt tensioning spring (B). The measurement
should equal 10-1/4" (26 cm) ± 1/8 (0,32 cm). If not,

rotated. Injury may result if the idler arm is prematurely
released while the spring is under tension.

clockwise, which will relieve the tension on the belt
exerted from the idler arm. Remove the belt from the rear
