Shaft Installation via Key Connection
On the EAS
®
-compact
®
with a keyway, the clutch must be axially
fixed onto the shaft after mounting, e.g.
with a press cover and a screw, screwed into the shaft
threaded center hole (for Types 490._2_._ and 493._2_.0)
and/or a locking set screw (for Types 494._2_._ and
496._2_._):
locking set screw (26) for hub (23.3), see Fig. 1 on page
3 and table 10 on page 7,
locking set screw (37.1) for hub (37), see Fig. 1 on page
3 and table 15 on page 9.
Joining Both Clutch Hubs (Items 1 / 16)
for Type 493._ _ _.0 (Fig. 1)
When mounting the hubs (1 and 16), the joining
force must not be transferred via the steel
bellows
=> danger of bellows deformation.

Joining Both Clutch Components (1/23)
for Type 494._ _ _._ (Figs. 1 and 6)
The flexible elastomeric element (22) is pre-tensioned between
the metal claws by joining components 23.1/23.2/23.3 with
component 21. To do this, an axial installation force is required.
The force required can be reduced by lightly greasing the
elastomeric element.
Use PU-compatible lubricants (e.g. Mobilith
SHC460)!
No unpermittedly high axial pressure should be
placed on the elastomeric element (22) in
completely assembled condition.
Keep to distance dimension "E" acc. Fig. 6
and Table 10!
Joining Both Clutch Components
Type 496._ _ _._ (Fig. 1)
Join the misalignment-flexible part and the overload clutch and
screw together with cap screws (Item 30) to the tightening torque
given in Table 5.
The cap screws (Item 30) must be protected using a screw-
securing product, e.g. Loctite 243.
The clutch or clutch hub carries out an axial
movement in the direction of the cone bushing
(Item 13) when tightening the cone bushing
(13).
Because of this effect, please ensure that on
the EAS
®
-compact
®
clutch with disk pack (Type
496._ _ _._), first the cone bushing (13) is
completely tightened, then the other (disk pack)
side.
