Shaft Installation via Key Connection
On the EAS
®
-Compact
®
with a keyway, the clutch must be axially
secured both EAS
®
-side and lastic-side after mounting onto the
shaft, e.g.:
for Types 490._24._ and 493._24.0
with a press cover and a screw, screwed into the shaft
threaded centre hole
for Types 494._24._ and 496._24._
on the EAS
®
-side with a press cover and a screw, screwed
into the shaft threaded centre hole and on the lastic-side
with a locking set screw:
Locking set screw (20.4) for hub (20.3), see Fig. 1 on
page 3 and table 10 on page 7,
Locking set screw (35.1) for hub (35), see Fig. 1 on page
3 and table 13 on page 8.
Joining Both Clutch Hubs (Items 1 / 27)
Type 493._ _4.0 (Fig. 1)
When mounting the hubs (1 and 27), the joining
force must not be transferred via the steel
bellows
=> danger of bellows deformation.

Joining Both Clutch Components (1/20)
Type 494._ _ 4._ (Figs. 1 and 7)
The flexible elastomeric element (19) is pre-tensioned between
the metal claws by joining components 20.1/20.2/20.3 with
component 18. 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 (19) in
completely assembled condition.
Keep to distance dimension “E” acc. Fig. 7
and Table 10!
Joining Both Clutch Components
Type 496._ _4._ (Fig. 1)
Join the misalignment-flexible part and the overload clutch and
screw together with cap screws (Item 40) to the tightening torque
given in Table 5.
The cap screws (Item 40) 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 15) when tightening the cone bushing
(15).
Because of this effect, please ensure that on
the EAS
®
-Compact
®
clutch with disk pack
(Type 496._ _4._), first the cone bushing (15) is
completely tightened, then the other (disk pack)
side.
