Tech Note 1182 Detail

Only 3 wheels of the cart touch the track.

Affected Products:

ME-6950 PAScar (Set of 2)

Only 3 wheels of the cart touch the track.

PASCO Solution:

This condition typically does not affect the performance of the carts and may disappear when the carts are loaded.

If the tracks are level, this condition can be easily fixed by adjusting the tension of the 10 mm Torx screws (T10 driver) that hold in the wheels:

  1. Remove any load from the cart.
  2. Check that all of the suspension springs are in place. If not, contact Teacher Support for replacements.
  3. Tighten any Torx screws that are loose.
  4. Alternately compress and decompress the suspension a couple of times to make sure that the springs are fully set.
  5. Check for a wheel that does not contact the track.
  6. Slightly back out the Torx screw underneath that wheel and check it again.
  7. Repeat Step 5 until the wheel touches the track.
  8. Repeat Steps 4-6 for any other wheels that do not touch the track.
