ELECTRICAL MAINTENANCE
DIAGNOSTIC TERMINAL BOX
Your Tractor is equipped with a Tractor Diagnostic Terminal
Box which is used to simplify electrical system diagnosis. The
Iocation of the Diagnostic Terminal Box is shown in Fig. 14.
The Diagnostic Terminal Box provides access to a number of
test points within the electrical system of the tractor.
WHEN USING THE DIAGNOSTIC TER-
MINAL BOX - ENGINE TO BE STOPPED
AND IGNITION OFF,
USE PROPER EQUIPMENT IN THE
CHECKING OF ELECTRICAL SYSTEM
THROUGH THE DIAGNOSTIC TERMIN-
AL BOX.
The Diagnostic Terminal Box is designed to accept the Diag-
nostic Terminal Adapter (optional) (Fig° t5), which is avail-
able from Sears (Part No. 677A823)_ If you order the Adap-
ter, also order the Test Procedure Manual (Manual Nor 8441J),
showing diagnostic procedures and components of electrical
circuits°
To perform the testing with the Diagnostic Terminal Box, a
quality multimeter or automotive analyzer is required.

FIRST HOURS
1_ CHECK BELT ADJUSTMENT
New Belts may stretch after the first few hours of operation
resulting in lossof power.
amWith engine running, transmission in neutral, place Vari-
drive Control Lever in "FAST" position (Fig. 11) and
check if Secondary Belt (Fig. 16 - Inset) ridesflush 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
i f Be t cannot be adjusted as described in step g replace
