bolts (M10x40) that hold the
housing to the main housing.

keyholes. Lift the housing up
and then pull it forward to
remove the castor unit. If there
is difficulty in removing the
unit, remove the top two bolts.
f) Remove the nut (M20), pull
out the shaft and replace the
drive castor.
g) When replacing the drive
castor, ensure that the shaft
key aligns with the keyway in
the housing.
h) Tighten the nut (M20) so that
there is no play between the
drive castor and housing. Take
care not to tighten the nut too
tight, or the castor will not turn
freely.
