REMOUNTING
By means of a tube with the outer diameter Ö51mm and a press, mount the bearing up
to t he c onnection with the drum support surface (carefully not to da mage the sealing ri ng). Set back:
- a new lock;
- the drum on the steeri ng knuckle, previously greased with grease;
- a new nut M20 x 1.5 and tighten at the re quired moment;
- the drum plug.
A djust:
- the shoes by applying a repeated pressure on the bra ke pedal;
- hand brake (see chapter 37-“Control s”). BEARING (25 x 52 x 37)

WHEELS AND TYRES
CARACTERISTICSRIMS
The wheels identification marking is represented in two ways:
- engraved marking for steel rims
- cast marking for aluminum rims
The marking enables acknowledgment of the main wheels dimensions criteria. This marking
may be:
complete,
Example: 5
1/2 B 13 4 CH 46 ; 5 1/2 J 13 4 H2 46
or simplified,
Example: 5
1/2 B 13 ; 5 1/2 J 13 H2
The wheel bolts (studs) are situated on a diameter of 100 mm.
Maximum axial runout : 1 mm measured on the rim edge ( in G ).
Maximum radial runout : 1 mm measured on the supporting side of the tires beads.

The wheels screws tightening moment : 7,5 daNm.
The inflating pressure must be checked at cold.
The temperature raising during driving, leads to a pressure increase from 0.2.
to 0.3 bars. In case temperature checking is done at warm, take i nto account this pressure increase and
never deflate it. A
