Its extensive modularity allows the removal and insertion of bearings
having a minimum diameter from 62 mm up to a maximum diameter
of 85 mm.
This tool set can be used directly on the car, without having to
disassemble the king pin/hub/bearing unit from the car and placing
it on a press.
OPERATION
Both the removal and the insertion steps can be carried
out on-board the car.
REMOVAL
During the removal stages, the tool set's modularity consists in
its innovative removal semirings (A) the diameter of which can be
changed by means of intermediate spacers (B) (see fig. 3) so as to
adapt to the diameter of the bearing to be removed.
After releasing wheel, brake caliper, brake disc, drive shaft, etc.
(see fig. 2) from the support, remove the bearing, by assembling the
following tool set components as shown in fig. 3:
•
2 removal semirings (A) as shown in the figure, with spacers (B),
where applicable;
•
Removal ring, sized according to the bearing diameter (C);
•
Thrust bell (D);
•
Screw M20x1.5 (E);
•
Nut + bearing (F);
•
Counter-nut (G).
Manual operation
- Manually tighten only the nut + bearing (F) on the screw
M20x1.5 (E). During this phase it is important that the counter-
nut (G), the removal ring (C) and the integrated HBU bearing
all move together (jointly) towards the bell until it comes out
completely from its seat (Fig.4).
The bell is sized such that it can fully house the hub during the
removal stages (fig. 5).
Operation with 17-ton hydraulic cylinder
(UPGRADE
OPTION - 1952 004 090)
- EWhen performing the operation using the 17-ton hydraulic
cylinder, fit the cylinder between the bell and a second counter-
nut (G) (Fig.6).
Now actuate the cylinder that, by axially translating the screw,
allows you to remove the integrated hub from its seat.
