FIRST HOURS

1_ CHECK BELT ADJUSTMENT

New Belts may stretch after the first few hours of operation

resulting in loss of power.

am With engine running, transmission in neutral, place Vari- drive Control Lever in "FAST" position (Fig. 11) and

check if Secondary Belt (Fig. 16 - Inset) rides flush with outside of Variator Sheave (DO NOT PUSH DOWN ON

CLUTCH PEDAL).

b, If Secondary Belt is riding down in groove of Variator Sheave adjustment is required,

2.V-BELT ADJUSTMENT

a With engine running, Transmission in "NEUTRAL" position, move Varidrive Control Lever to full "FAST"

position (Fig. 11)

b. Shut engine off and loosen Adjustment Nut on Bolt "A" for Variator Stop Plate (Fig. 16).

c, Start engine and run at idle Speed

d Slowly move Vafidrive Control Lever (Fig. 11) forward or backward until Secondary Belt is riding flush to 1/16" outside of Variator Sheave (Fig 16 - Inset).

NOTE: DO NOT PUSH DOWN ON CLUTCH PEDAL. e., Shut engine off holding Varidrive Control Lever in posi- tion as described in step d and tighten Adjustment Nut

on Bolt "A" (Fig. 16).,

f, Start engine and move Varidrive Control Lever to SLOW posttlon (F_g. 11). Primary Belt should ride flush to 1/16" out of Variator Sheave (Fig. 16 - Inset).

g Adjustment is complete when the Secondary Belt rides in the same position on the Variator Sheave in full "FAST" position, as the Primary Belt does in the "SLOW" position,

h Re-adjust as needed thereafter

if Be t cannot be adjusted as described in step g replace V-Betts= Refer to Belt Replacement , page 12.

3.CHANGE ENGINE OIL
