ASSEMBLY PROCEDURE
The transmission is assembled in modular fashion and details
of assembly for each module are given under the appropriate
subject. Refer to table 8.1 (at the end of Section 8.3) for the
torque specifications to be applied, and to table 9.10 in section
9.6 for details of all special tools required, when performing
assembly procedures. Technicians overhauling these
transmissions will also require a selection of good quality Torx
bit sockets, in particular numbers 30,40 and 50, and an 8 mm,10
mm and 12 mm double hex socket.
Transmission
Notice
1. Ensure that the B1R circlip is fitted to the case. (If this is not
fitted, the valve will peen its way into and through the
separator plate.)
2. Ensure that the ‘E’ clip is fitted to the cross shaft.
3. Ensure that all aspects of the parking mechanism are
working.
To assemble the transmission, proceed as follows:
1. Turn the transmission case upside down on the bench and
mount it to the transmission cradle No.0555-331895.
2. Install all fittings, plugs and the breather, applying a sealant
where applicable, Tighten the fittings to specifications.
Ensure that the breather is clear, and check that the lube
fitting in the rear of the case is fitted and clear of obstruction.
3. Assemble the B1R valve and spring, and secure with the
irclip. Refer to Ensure that the circlip is completely seated
in its groove.
4. Install the rear servo lever and pivot pin.
