The figures show the disassembly of a size 420 wheel. The removal of other wheels does not essentially differ from this

   Clamp the wheel in the end carriage. It does not matter which side faces inwards or outwards.

   Insert the bolt and distance bush. If necessary, lightly hammer the bolt and distance bush.

   Attach the circlip and neatly lock into place.

   Turn the wheel.

It must move easily.

   Place the coupling bars on the end carriage so the markings (for the installation direction) match.

   Move the coupling bar so that the holes for the flanged bolt are on top of one another.

Tip:

To make positioning the coupling bar easier, insert a rib screw M12x50 with a rib nut M12 into the openings on the edge of the coupling bar and adjust the position of the coupling bar by turning the rib nut.

   Screw a screw M10 or M12 or a threaded rod into the flanged bolt.

   Push the flanged bolt from inside through the hole.

   Guide the flanged bolt with the aid of the screw or threaded rod, and push it right through the coupling bar.

   Put on the cover.

   Screw the rib screws in.
