This tool is designed for use as an aid in properly adjusting belt tension on most motorcycles equipped
with a secondary drive belt; always refer to your service manual for the location to check your belt and

proper belt tension specication.

1. Position the small O-ring on the tool directly over the 10 lbs. mark on the shaft.

2. Position the U-shaped belt cradle against the lower bottom strand of the belt. Making sure the tool is
perpendicular to the belt.

3. Push upward on the rubber bumper until the small O-ring just touches the bottom of the tool body;
this means 10 lbs. has been applied to the belt, If your model does not have a method of determining the

amount of belt deection you can use the large O-ring and graduated scale on the body to calculate the
amount of belt deection. With the U-shaped belt cradle against the lower bottom strand of the belt nd a

reference point on the bike to align the large O-ring with and record the reading on the graduated scale.
After pushing upward on the rubber bumper until the small O-ring just touches the bottom of the tool body
align the large O-ring with the same reference point on the bike and record the reading on the graduated

scale. The difference between the initial reading and the nal reading is the belt deection at 10 lbs. force.
Always refer to the service manual for specic specications for the model being serviced.
