1. CHECK BELT ADJUSTMENT
New Belts may stretch after the first few hours of operation
resulting in loss of power.
a. 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 Varidrive 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 Boit"A" (Fig. 16).
f, Start engine and move Varidrive Control Lever to
" slow " position (Fig. 11). Primary Belt should ride
flush to 1/16" out of Variator Sheave (Fig. 16 - Inset).
g Adjustment is complete when the Secondary Beit 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.
i- if Belt cannot be adjusted as described in step g, replace
V-8ettSo Refer to Belt Replacement , page 12,
