MULE DRIVE BELT TENSION:

1.Stop engine and remove the key.

2.Check to make sure the bolt head in the spring loaded idler pulley, on the left side of the engine deck is positioned between the two alignment holes in the left support plate

(See Fig 4).

3.If adjustment is necessary, loosen the adjustable idler pulley on the right hand side of the engine deck so it can move up and down in the slot. Place a wrench on the 3/8" nut in the center of the spring loaded idler pulley and rotate the idler upward to relieve the tension on the belt. Reposition the right side pulley in the slot and tighten. Recheck alignment of the bolt on the spring loaded idler.

THROTTLE LEVER TENSION:

1.Stop engine and remove key.

2.If throttle lever becomes loose, tension may be adjusted by tightening the pivot bolt. The pivot bolt holds the throttle arm to the throttle mounting bracket which is located under the console. Access is gained by removing the foot plate and the kick plate. See page 3.

REVERSE SPRING DETENT ADJUSTMENT:

1.Stop engine and remove key.

2.Rotate seat latches out to release seat. Located at the bottom rear of seat. Put seat in rear slide position, tilt seat forward, remove seat stop rod bolt and nut, tilt seat forward to rest on front frame.

3.Start with either the right or left motion control lever. Move the motion control lever to the neutral position then pull the lever back until the clevis pin (on the arm below the pivot shaft) comes into contact with the end of the slot. At this point slight spring pressure should be felt ( See Fig 5a).

4.Check where motion control lever is relative to the neutral slot in the console. The lever should be centered to allow it to pivot outward into the neutral slot.
