T h e inboard C.V. joint is equipped with a male splined spigot shaft which engages with the female splines
of the differential output sun gear, and is retained by a round section spring circlip on its end. Each of the two
transmission output oil seals runs on a stepped shoulder on the C.V. joint spigot shaft. T h e outboard e n d of
each driveshaft carries a second C.V. joint whose spigot shaft is used to clamp the hub and wheel bearing into
the hub carrier via a thread on the end of the shaft.

Revised Transmission Output Seals
In order to reduce the possibility of seal
d a m a g e during driveshaft insertion, the two
transmission output shaft seals were modified
in July '96, a n d fitted f r o m t r a n s m i s s i o n
number C 6 B P 2 0 0 9 7 1 3 . T h e new 'B' type
seals incorporate a steel insert to protect the
seal lips, and have a location flange on their
outside diameter.
W h e n replacing a seal, compatibility with
the driveshaft (see below) must be maintained.
Although the transmission casing was revised
for the 'B' type seal to include a machined face
for the seal flange to butt against, if neces-
sary, a 'B' type seal may be fitted in an earlier
type casing.
With the introduction of the 'B' type seal,
a corresponding change to the C.V. joints was
made in order to provide clearance for the
steel insert in the seal, with an identification
groove being added to the joint's outer sur-
face for ready reference. The new joint may
be fitted to both new and old type transmis-
sions/seals, but the o l d t y p e j o i n t m u s t n o t
be fitted into a new type transmission or
'B' type seal.
