OPERATION
DISASSEMBLY: it can work on bearings with an external diameter
from Ø62 mm up to Ø85 mm.
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
OPTION - 1952 004 090)
- When 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.
- Since the cylinder has a max stroke of 43 mm, if the removal
was not performed completely, this operation can be repeated
several times by discharging the hydraulic cylinder (single-acting
cylinder with spring return) and then tightening the counter-nut
(G) again against the cylinder.
We recommend the use of the cylinder combined with the 700-bar
manual hydraulic pump, 1952 004 001, in our WÜRTH catalog.
