important the belleville washers are installed in the configuration shown in
Figure 1-22.
4b Place the screw support bracket in front of the carriage screw. The two
threaded holes in the bracket should face the two matching holes in the
carriage. Loosely install the two 1/4 x 1/2-inch button-head screws.
4c Before tightening the screws, apply some pressure to the bracket to
compress the belleville washers. The handle should still turn freely, but the
turning force should now be around five to six pounds.
To adjust the force needed to turn the crank handle, adjust the compression
of the belleville washers.

While installing the calibration weights, you should notice the Torque Gauge on the
DynoTrac Window moving from 0 to about 500 foot-pounds.
Note: The Torque Gauge may or may not be in this range.
• If the torque cell has been previously calibrated incorrectly or has not been
calibrated for a while, the gauge may show values out of this range until
calibration is complete.
• If you use the bolt pattern in the center of the calibration arm, the gauge will
show values around 250-260 foot-pounds.

purposes only and may not read correctly. The gauge remains uncalibrated until the
calibration process is complete.
• If the torque cell has been previously calibrated incorrectly or has not been
calibrated for a while, the gauge may show values out of this range until
calibration is complete.
• If you use the bolt pattern in the center of the calibration arm, the gauge will
