MAINTENANCE INFORMATION
6. Shake loose particles out of the screen assembly.
7. Clean the screen with a wire brush. (Soak it in oil solvent
if necessary.)
8. If any breaks in the screen or weldments are discovered,
replace the assembly with Part No. 607-171.
9. Return the screen assembly to the tailpipe and outlet tube
assembly and re-fasten it with the screw and internal tooth
lock washer from Step 4.
7.2 DRIVE SYSTEM & TIRES
Do not attempt to adjust, repair or replace the drive belt,
clutches or any moving part while the engine is running.
Doing so will cause injury. Before servicing the vehicle,
disconnect the battery to prevent accidentally starting
the engine.
Keep the engine compartment hood, clutch guard and
firewall securely in place when the engine is running.
Severe injury can result if the drive belt, clutch compo-
nents or other moving parts come loose.
If engine compartment inspection is necessary while the
engine is running, use EXTREME CAUTION! Keep en-
gine RPM low. Avoid standing directly in line with mov-
ing components. Use a mirror to view the components.
7.2.1 DRIVE BELT
The drive belt transmits power from the driver clutch (on
the engine) to the driven clutch (on the transmission). These
components are located on the left side of the engine compart-
ment (Figure 7-3).
Figure 7-3. Location of drive clutches and drive belt.
Check the drive belt after every 25 hours of operation, or
whenever there is a noticeable reduction in clutch perfor-
mance. Replace the belt when:
•
the top width of the belt has worn to 1-1/16" (27mm)
•
cracks, fraying or shredding is apparent
•
it becomes contaminated with oil or some other fluid
Refer to the ARGO Parts Manual for correct drive belt part
number.
Drive Belt Adjustment
To extend the life of the drive belt, the INVANCE driven
clutch allows for some adjustment to reset the belt height if
necessary. If belt wear causes the belt to start sitting below
the sheaves at idle, adjustment can be made to bring the belt
back up to flush or 1/10" above the sheaves.
1. Remove the driven clutch from the vehicle and move to
a clean work bench.
2. Loosen both jam nuts located on the fixed face of the
clutch. Figure 7-4.
Figure 7-4. Loosen jam nuts.
3. Using an allen wrench, turn the adjustment set screw
either in (to lower the belt) or out (to raise the belt) be-
tween the clutch sheaves. Figure 7-5.
IMPORTANT
Loosen set screws uniformly 1/2 turn at a time. It is
crucial that the clutch faces remain true and parallel to
each other around the entire circumference of the sheaves.
