Mounting the YZ-Car and adjusting its lower wheel bearings
Place YZ-Car on the X-Car
The YZ-Car is a single piece that is ready to be placed onto the rails that cross the face of
the X-Car beam.
• Roll the X-Car up to the far left side of the table and clamp it in place to make the
installation easy.
• Remove the lower wheel bearings before setting the YZ-Car in place. Notice that
these bearings are on an eccentric (adjustable) bushing and that there is a small,
precision washer behind the bearing and bushing. This washer is critically important.
• After you have removed the lower bearings, lower the YZ-Car down onto the rail,
seating the upper bearing wheels on the upper Y-Rail. The car will sit in place on
these top bearings.
