We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the hubs lightly (approx. 80 °C) allows for an easier mounting on the shaft.
STOP
Touching the heated hubs causes burns.
Please wear safety gloves.
!
With the assembly please make sure that the distance dimension E (see table 1 and 2) is
observed to allow for axial clearance of the spider when in operation.
Disregarding this advice may cause damage to the coupling.
Mount the hubs on the shaft of driving and driven side (see illustration 5).
The internal sides of the hubs must be flush with the front sides of the shafts.
Shift the power packs in axial direction until the dimension L
R1
is achieved (see illustration 1).
Fasten the hubs by tightening the setscrews DIN EN ISO 4029 with a cup point (tightening torque see table 3).
