GSP9700 Series Road Force Measurement System Operation 7. Calibration and Maintenance 129
7.5 Spindle Hub Face and Shaft Maintenance
Keep the shaft and wing nut threads clean and lubricated. Lubricate the shaft without
contaminating the hub face. Select “Clean Spindle Threads” from the “Balance”
primary screen. Run the edge of a rag between the threads while the spindle is
slowly turned by the motor drive. If any signs of dirt or debris appear on the spindle
threads, the spindle should be cleaned immediately prior to mounting a wheel.
CAUTION: Failure to clean spindle properly will result in a loss of
clamping force. Due to the force applied to the wheel by the
load roller, it is critical to maintain optimum clamping force.
Lubricate the shaft with a coating of light lubricant with Teflon
®
such as Super Lube
®
by Loctite after cleaning. Do not lubricate the spindle hub face mounting surface. This
could cause slipping between the wheel and the hub face. Keep the hub face
mounting surface clean and dry.
7.6 Mounting Cone Maintenance
Keep the mounting cones clean and lubricated. Lubricate with a coating of light
lubricant with Teflon
®
such as Super Lube
®
by Loctite.
Do not use cones in any way that is not described in this operation manual. This
could cause damage to the mounting cone and not allow for proper mounting of the
wheel.
