retained on the gearbox as described, dismantle the
overdrive unit in the following order, with the
front end uppermost:-
Remove the operating valve, as described under the
heading "The Operating Valve". This will allow air
to enter the cylinders of the operating pistons and
will thus facilitate removal of these pistons.

the valve seat in the valve orifice using VLC. Key
L.213. Remove the body retaining screw. Screw
VLC. Tool L.205 into the pump body and withdraw

assembly to the o/s of the unit (adjacent to solenoid).
Remove cover.
Remove 2 screws securing solenoid to casing. Ease
plunger out of operating lever yoke and remove
solenoid.
Release the lockwashers securing the four ¾' nuts
retaining the operating piston bridge pieces.
Remove the nuts, lockwashers and bridge pieces
and withdraw the operating pistons by gripping
their spigots with pliers.
Disconnect the balance pipe, if fitted.
Loosen and progressively remove the eight¾' nuts
around the centre flange of the casing. This will
gradually release the four clutch springs. Remove
front half of casing complete with brake ring. Take
the four clutch springs off their pegs on the thrust
plate.
The brake ring is spigoted into each half and will
normally come away with the front half of the
casing. A few light taps with a mallet around its
flange will remove the ring from the rear casing.
Lift out the clutch sliding member complete with
the thrust bearing and sunwheel. If the cone clutch
sticks in the brake ring, a light tap with a mallet
on the rear end of the casing will free It.
Remove the sunwheel from the sliding cone clutch
member by withdrawing the sunwheel clrcllp from
its groove in the forward end of the sunwheel hub.
Remove the thrust bearing and the thrust plate by
removing the large circllp and pressing out the cone
clutch hub from the thrust plate and bearing.
Remove bearing from thrust plate assembly using
VLC. Special Tool.
Remove planet carrier assembly. If necessary to
remove roller clutch, first remove circllp and brass
locating ring which is in an annular recess in front
of the clutch.
Place fitting ring (VLC. Special Tool L.178) centrally
over the front of the annulus and lift the Inner
member of the uni-directional clutch Into it. This
will ensure that the rollers do not fall out of the
inner member. Remove the fitting ring and place
the parts in a suitable container. Remove the spring
ring, located between the hub and the cage.
Remove the bronze thrust washer fitted between
the clutch inner member and the front face of the
annulus.
