Replacing the Wheel-Axle Assemblies (PASCO ME-6957A - set of four)
Warning! When the baseplate is removed, the wheel-axle assemblies may pop upward because they are supported on
compressed springs. Pull the baseplate with one hand and cover the wheel-axle area with the other hand. This will help
keep the wheel-axle assembly from popping out.
1. Using a Phillips screwdriver, remove the screws from the
non-plunger end cap.
NOTE: The screws that connect the end cap to the body of
the Plunger Cart are thread-forming screws and may require
substantial force to remove and reinstall. A #1 Phillips point
screwdriver is recommended.
2. Position the Plunger Cart with the baseplate facing
upward.
3. Begin to slide the baseplate out of the cart. Be careful to
“catch” each wheel-axle assembly as it is uncovered.
4. With the car in a stable position, lift the wheel-axle
assemblies from the grooves.
NOTE: Be sure to keep the components such as springs,
plunger, and magnets in their proper orientation. Rearranging
or moving any items could change the operational capability
of the Plunger Cart.
5. Place the new wheel-axle assemblies over the suspen
-
sion springs.
6. Push the rear axle down against the springs first, and
slide the baseplate back into a position that covers the
wheel-axle assembly.
7. Push the front axle down second, and slide the baseplate
all the way back into its original position.
8. Replace the non-plunger end cap with the two screws.
