How to replace wheels and axles on the Series 1, 2, and 3.

Features

  • Series 1 Axle - 6"
  • Series 2 Axle - 9.25"
  • Series 3 Axle - 11"

Installation Instructions Below:

Tools needed: two 10 mm (7/16 in) wrenches

You will need 2 wrenches 7/16" or 10mm or two adjustable ones.

Loosening both locknuts with two wrenches

1. While grasping both locknuts with wrenches, turn counterclockwise to loosen each nut. If one side is removed before the other, it may become necessary to use pliers or another method to prevent the axle from rotating while the remaining locknut is loosened.

2. Once both locknuts are removed, the wheels should slide off of each side.

Incorrect axle position: the shouldered end on the wrong side

Incorrect position: the smaller, shouldered end of the axle on the wrong side.

Correct position: the small end enters and exits through the larger hole

3. As shown above, each side of the axle is machined to different diameters resulting in an asymmetrical axle to secure the axle assembly inside the plastic. The axle is only removeable/insertable through the larger of the two holes drilled in the plastic of the case. If not easily removed, please ensure you are attempting to remove it in the correct direction before using additional tools to hammer, push or pull from the plastic, as doing so could result in irreparable damage.

4. Insert the new axle into the larger of the two holes in the lower half of the case. The smaller end of the axle should protrude slightly.

Once axle is installed, if you are replacing your wheels, install them now.

Once wheels have been replaced, it is recommended to hand tighten locknuts first to avoid cross threading.

Finally, tighten each side with wrenches and replacement is complete! Please note: there is no specific recommended torque value other than sufficiently tight.
