CAST IRON REAR DRIVE AXLE

 REAR DRIVE AXLE  OF CAST IRON

DACIA 1304,  1307 ( supplier ARO CÂMPULUNG )

CHARACTERISTICS

It  is a  rigid type cast iron  axle, with differential and  propeller shafts.
It is attached to the chassis by means of the half-elliptical springs and the hydraulic shock

absorbers.

The main transmission is simple type , with hypoid gearing between the pinion and the rim.
The differential is symmetrical, simple, with two differential conical pinions.

IMPORTANT !

  

The interchangeability of the cast drive axle with the pipe axle  ( assembled axle ) is

depenedent of the replacement of the shock absorbers, springs attachment plates,
attachment clips from the springs and shock absorbers buffers.

NOTE:

The dismounting – remounting steps of the cast drive axle ( as an assembly ) are

the same as the ones for the drive axle made of plate, previously presented.
