Drive Belt Removal
The Invance Driven Clutch (transmission clutch), is
manufactured with a 6mm x 1.0 threaded hole in the clutch
face. This hole is provided to assist in spreading the driven
clutch pulleys apart by threading a 6mm x 1.0 thread bolt in
through the face. This bolt should be a least 2” in length with
full thread. Spreading the pulleys allows for easy removal
and installation of the 127-137HD drive belt. Figure 7-2c.

Drive Belt Installation
If this procedure is not carried out as described, the edge
of the fixed face may cut or damage the drive belt.
1. Position the belt around the driver clutch first.
2. Ease the belt over the edge of the fixed face on the driven
clutch and at the same time, turn the inside, movable face
clockwise.
Drive Belt alignment and tension are pre-set at the factory
and are not adjustable. They are critical for proper operation
of the drive system. Return the vehicle to an ARGO dealer if
rapid belt wear occurs.
7.2.2 CLUTCH MAINTENANCE
Disassembly and repair of the driver and driven clutch requires
special tools. Return the vehicle to an authorized ARGO dealer
if the clutch units need servicing. The following indicates that
clutch service might be required:
•
a drop in vehicle performance
•
the clutch does not shift smoothly

MAINTENANCE INFORMATION
Figure 7-2a. 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 7-2b.
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.
4. After adjustment, check belt level by placing a drive
belt between the sheaves. Belt position should be
anywhere from flush with the top of the sheaves, to
1/10" above. Re-tighten jam nuts and torque to 60-75 in.
