Replacing the steering head bearings on the steering wheels

CAUTION! Incorrect installation can damage the bearings and lead to the steering wheels
falling off!
· The single-row angular ball bearing rings are not identical on both sides. This is why there is
only one correct way of fastening them. The assembly instructions must, therefore, be
followed exactly.
Required parts/tools:
· 19 mm socket wrench
· Torque spanner
· Large screwdriver, flat
· Wooden chock (approx. 12 x 12 x 30 cm) for jacking up the vehicle
·
Use the wooden chock (1) to jack up the
wheelchair on the side on which the ball
bearings are to be replaced.
·
Carefully remove the plastic cap (1) using
the large screwdriver.
·
Use the socket wrench to loosen and
remove the 19 mm nut. Hold the wheel in
such a way that it is not able to rotate when
the nut is removed.
·
Pull the steering head shaft downward and
out of the steering head tube.
·
Remove the shim and the ball race from the
head of the tube. The other ball race should
be on the shaft.
