Replacing the Wheel-Axle Assemblies
1. Using a Phillips screwdriver, loosen the screws and remove the bottom cover plate.
NOTE: The screws that connect the two halves of the PAScar are thread-forming screws and may
require substantial force to remove and reinstall. A #1 Phillips point screw driver is required.
2. With the car on a stable support, gently lift the wheel assemblies from the plastic grooves.
NOTE: Be sure to keep the components, such as springs, plunger, nuts and magnets in
their proper orientation, as shown in Figure 6.3. Rearranging or moving these
items could change the operational capability of the PAScar.
3. Place the new wheel/axle assemblies over the suspension springs.
4. Place the bottom plastic cover over the wheel/axle assemblies, such that the vertical
grooves on the cover align over the axles. Align the bottom cover flush with the frame.
Replace the screws and tighten them until the cover fits snugly against the outside frame.
NOTE: When replacing the cover, be careful not to knock the
plunger release spring or plunger spring from its holding place.
