Remove the half shells from the hub body (see illustration 6).
Put the hub body with the cap screws installed on the shaft (see illustration 7).
Position the half shells towards the hub body (see illustration 8). Screw in the cap screws for several pitches.
The radial kerf of the DH clamping hubs must be flush with the front sides of the shafts.
Hand-tighten the components first until the hub bodies with the half shells fit closely to the shaft.
Secure the DH clamping hubs by tightening the clamping screws reciprocally. The screws have to be tightened
at the tightening torques T
A
specified in table 2 by means of a suitable torque wrench.
Shift the power packs in axial direction until the dimension L
R2
is achieved (see illustration 2).

Shift the ZR clamping hub onto the ZR intermediate
pipe (see illustration 9).
Insert the spiders in the cam section of the hubs or
clamping hubs DK, respectively.
Insert the pre-assembled unit between the hubs
(see illustration 10).
Align the ZR clamping hubs to the dimension E
resp. s required (see illustration 1 and 2 as well as
table 1 and 2).
Hand-tighten the ZR clamping hubs first. Tighten the
cap screws to the tightening torques T
A
specified in
table 1 by means of a suitable torque key.
Drill the through holes Ødp (see illustration 1 and
table 1) in the ZR intermediate pipe for the
setscrews with pin DIN EN ISO 4028.
Screw in the setscrews with pin against a stop.
