be pinched between the drum and outer rails so that it is
impossible to rotate them by hand. Move the wheels further on
and they should both simultaneously be released somewhere
between positions M and N. If this is not true, adjust the left
and/or right hand bearing plates as described in 4.2.2 above, but
without referring to the gaps between the rail ends and the drum.
It may be necessary to release and adjust the top or bottom rail
ends to clear the drum.
4.4.6 With the drum properly adjusted, reset the gaps between the
drum and rail ends to 0.2 to 0.5 mm by moving the rail ends.
This can be done by releasing the bolts holding the rail ends to
the side panels. Make sure that the rail ends join the rails
smoothly. It is best to first set the rail side of the rail end to give
a smooth joint with the rail and lightly tighten the bolt on that
side. Then set the other end to obtain the required gap with the
drum. Tighten all the bolts and recheck the gaps.
4.4.7 Make sure that the guide wheels are free to move between the
bottom rail ends and the outer rails.
4.5 Changing a tire
4.5.1 Park the bogie so that the rubber wheel is right above the drive
motor.
4.5.2 Refer to section 4.6 and remove both springs from the bogie.
Note that you will have to lift the wheel slightly by hand to pull
out the second spring. The wheel will now rest on the drive
motor.
4.5.3 Remove the 300mm wheel from the bogie:
Refer to fig 8 and undo and remove the two M24 nuts, A & B,
at the ends of the wheel axle. Remove the stiffener plate, G, by
removing the six hex drive cap screws marked, F. The two
trailing arms, C & D, are held in position on the guide wheel
axle by two circlips each. Use circlip pliers and move the outer
circlip of one of the trailing arms as far as it will go towards the
