Loosen clamping screw of the coupling half on the motor/ gear shaft:
ETH032, ETH050, ETH080:
Loosen radial clamping screw of the coupling half (see Figure 14 Pos. 3).
ETH100&125:
Loosen all clamping screws (see Figure 15 & Figure 16 pos. E2) carefully
(approx. 3 mm) and screw two of the screws into the open threaded holes.
Now tighten screws evenly until the clamp collar (please refer to Figure
17 Pos. 4) is released from the coupling hub (please refer to Figure 16 Pos. 2)
and can be freely moved.
Remove coupling half from the motor / gear shaft.

Loosen clamping screws of coupling halves for the motor/ gear shaft.
ETH100&125: Clamp collar (see Figure 18 Pos.4) and clutch hub (see Figure
18 Pos. 2) must be loosened.
Slip the coupling half onto the motor / gearbox shaft and align to be flush with
the shaft if not stated otherwise by Parker (see Figure 18 Pos. 2).
ATTENTION!
Shafts and bores of the hubs must be free of burrs, dirt and grease.
ETH032, ETH050, ETH080:
tighten radial clamping screw with tightening torque (see Table 1).
ETH100&125:
Tighten the fixing screws (please refer to Figure 18 Pos. E2) crosswise with a
torque wrench in 3 turns with 1/3, 2/3 and full tightening torque (please refer to
Table 1) until the final tightening torque is attained and the clamp collar touches
the coupling half. The dead stop (please refer to Figure 19 Pos. 1) on the
coupling half (please refer to Figure 19 Pos. 2) prevents too high pretension of
the conical clamp collar and ensures high rotational accuracy.
The second coupling half and the elastomer ring of the coupling are mounted on
the ETH cylinder at the factory. If not, fit the elastomer ring onto one of the
coupling halves.
Joining with the Elastomer crown requires an axial mounting force. This force can
be reduced by cleaning and lightly greasing the spider element and the contact
surfaces.
ATTENTION!
Oils and greases containing molybdenum disulfide or other high pressure
additives as well as sliding grease paste may not be used.
Place motor/gearbox on the mounted flange, so that the coupling halves
intermesh.
Secure motor/gearbox against dropping.
Eye bolts must be used with suitable lifting devices for motors and gearboxes with
eyes bolts.
Equip screw with washer and tighten (please refer to Figure 14 Pos. 6, Pos. 7).
