Place the spring onto the axle.
Mount on the main wheel to the
back post:
-
Insert the axle trough the ball
bearings of the post.
-
Now push the wheel and post
towards each other, so the
spring is pressed together and
the end of the axle protrude far
enough to make it easy to push
one of the retaining rings into
the groove of the axle.
This retainer has a small
protruding edge for your nail to
pull it out again; naturally this
edge should face outside.
The parts of the “footman bolt
assembly” are already assembled
in correct order onto the socket
head bolt: first the ball bearing,
then the spring ring and at last the
bigger washer. Screw this
assembly into the hole in the
wheel. Use the Allen key to
tighten.
