Replacing the wheel/axle assemblies on our Dynamics Cart and Track System (DTS) carts is fairly simple. You will need new wheel/axle assemblies for the ones you are replacing. They can be purchased here: Vernier Dynamics System Axles and Wheels for Cart (WHEELS-VDS).

1. Remove the cart end cap using a 3/32-inch hex wrench.
2. While pressing axle down, slide the retaining pins out.
3. Swap old wheel/axle assembly for new one.
4. Hold new axle down while replacing retaining pins.
5. Re-install cart end cap.

Notes

• Center the new wheel/axle assembly in the cart so that the wheels do not rub on the cart frame.
• When replacing the wheel/axle assemblies on the plunger end of a Plunger Cart (DTS-CART-P), the process is the same. The end cap will not come off entirely – because of the plunger – but will separate far enough to allow you to proceed.
• When replacing the wheel/axle assemblies on Motion Encoder Cart (DTS-CART-MEC), the process is the same. Take extra care not to knock the encoder transmitter assembly out of position when removing/replacing the end cap or retaining pins.
