ISMO UNTING
Remove the two collars (5) taking care not to damage the channels made on the steering
knuckle surface.
Cut and remove the damaged bellows.
Take out maximum of grease.
For GE joint bellows replacement it will be necessary to dismount the joint parts
towards the gearbox (joint JI 69) ( see previously described method).

NOTE:
It is absolutely necessary to observe the prescribed grease quantity ( 26,0 cl ).
Position: the bellows reinforcements in the steering knuckle casing channels and in the shaft
rod channel.
Mount the GE joint collars.
Remount GI joint parts.

LONGITUDINAL TRANSMISSION ( CARDANIC )
II.LONGITUDINAL TRANSMISSION ( CARDANIC )
CHARACTERISTICS
Longitudinal transmission is specific and is equipping the D1304, D 1307 vehicles
(rear wheel drive or f.w.d. 4 W D) and has the purpose to transmit the motion from GB to
rear axle (drive axle). It is composed of three asynchronous cardanic joints open type and
two longitudinal cardanic shafts, the first one assembled to the gearbox, sustained on a
support with intermediary bearing, the second one assembled with the first and with the
main transmission, owing an axial compensating coupling (slotted joint).
In the cardanic joints areas there are mounted the lubricators G which have the purpose
to distribute the grease through the channels made for the access to the four bearings.
D
ISMO UNTING
Dismount:
- the four bolts M10 x 1,25 - 35 assembling the cardanic flanges to the side towards
the drive axle;
- the four bolts M10 x 1,25 - 35 assembling the cardanic flanges to the side
towards the drive gearbox;
- the two bolts M 8 x 1,00 - 25 positioning the transmission relay on the cross bar.
Dismount the cardanic transmission off the vehicle.
R
EMO UNTING
For remounting, perform in reverse order the dismounting operations.
Additionally, observe the following conditions:
- before assembly the shaft flanges must not show shocks marks, marks, paint
marks, oxides, etc.
- when assembling the intermediary support on the cross bar, the screws will be
oriented from top to bottom.

LONGITUDINAL TRANSMISSION ( CARDANIC )
IMPORTANT !
The cardanic joints forks which are mounted at the both ends of the longitudinal
transmission are to be placed in the same plane.

CARDANIC TRANSMISSION MAINTENANCE
In order to avoid arising of same problems in exploitation such as : noise, joint clearance,
nooses gutter wear, it is necessary to perform the greasing of the cardanic transmission
every 5000 km.
The operation is performed within adjust in within the periodical technical revisions by
means of the Tecalemit (grease gun).
This to be applied on the lubricators from the joints areas (cross-head) and the
corresponding lubricator to the gutters. Needle roller bearings and the gutter connection is
to be lubricates under pressure using UM 185 Li 2 type grease or its equivalent.
Greasing is considered adequate when by the sealing elements (gaskets) the old grease
is eliminated and the new one is coming out.
The intermediary support does not require maintenance.

GENERAL PRINCIPLE SCHEDULE OF A BRAKE CIRCUIT
IN PARALLEL WITH BY-PASS CIRCUIT
The DACIA commercial vehicles, are equipped with hydraulic braking system, double
circuit by-pass brake pump , brake amplifier, pressure limiter in order to avoid the rear
wheels blocking.
The front brakes are disk type and the rear brakes are drums type.
The brake disks are aerated, for the wheels with 5 attachment screws and non aerated
for wheels with 3 attachment screws.
