Rear Castor Wheels

•
Use the flat-bladed screwdriver to
carefully pry the rear plastic cover off, as
shown in the picture.
•
Prop up the wheelchair by lifting it up on
the side that you want to work on and then
placing the wooden block underneath the
battery box on that side.
•
Loosen and remove the 19 mm nut (1)
that holds the castor wheel using the socket
wrench. Hold the wheel so it does not rotate
while removing the nut.
•
Pull the steering head shaft down and
out of the steering head tube.
•
Remove the washer and the bearing
race from the top of the tube. The other
bearing race should be on the shaft.
IMPORTANT REASSEMBLY INFORMATION!
The pictures show the wide rim on the outside of the bearing race
(A) and the narrow rim on the inside (B).
The bearings must always be assembled so that the narrow rims
are facing each other (inwards)! The steering head bolt and the
nut must always press against the wide rims from the outside!
Otherwise the bearings will be forced out apart by the pressure of
the bolt!
