Maintaining the transmission on the press, on both sides, shall be ensured on the G
groove made on shaft, by means of a device type FACOM U 53 G, ( the flat side towards
bellows) in order to avoid the deflector damages on the wheel side.
The pressing effort of the bearing on the transmission shaft ahas the value of = 100 –
700 daN.
Press again the assembled tripod on the transmission shaft observing the marks made
when depressing.
The press effort of the tripod assembly on the grooved area of the shaft end, shall be
between 60 – 600 daN.
Remount the blocking ring (Zeger lock) in the groove made on the transmission shaft.

tulip of the transmission shaft.
Obturate the small extremity of the bellows
and, abundantly grease with automatic
transmission oil or ELF CARDREXA RNT

Introduce the smaller diameter of the
bellows on the PF 537 – 03 device.
Cover a hand with clean gauze and
place it on the bellows in such a way as to
stretch the first fold.
Take support with the hip on the edge
of the vice (lateral side).
Place the other hand around the first one
and strongly pull it, taking care that first
fold is not huddled together.
Bring the bellows as close as possible
to the device cylindrical part and let it
release till half stroke.
It is recommended to perform many
times this operation (maximum 5 times).
When easy slipping is noticed, make so
that bellows is passing over the device
cylindrical part, the operation being
performed without stopping.
