BELLOWS-BEARING ASSEMBLY

TO THE GEARBOX

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.

DISMOUNTING

Dismount the two maintaining collars

off the bellows by means of two rods,
locally manufactured (see the drawing)

Cut and remove the damaged bellows.
Remove as much grease as possible.

Mark one of the groove routes of the shaft

subject to its working corresponding clog by
marking with a centre punch on casing outer
consequently on the shaft.

REMOUNTING

The mounting of the new bellows is to be

performed by means of the PF 573 – 03
device.

Catch the inclined transmission in a vice

with soft jaws in order to avoid the shaft
damaging.

Engage the PF 537 – 03 device over the

tulip of the transmission shaft.

Obturate the small extremity of the bellows

and, abundantly grease with automatic
transmission oil or ELF CARDREXA RNT
2 grease:

- the  all outer surface of the PF 537 – 01

device

- the inner part of the bellows, especially

its smaller diameter part (this operation is
performed for slipping help).

BELLOWS TO WHEEL

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
