Tighten the head through bolt accurately, holding firmly in place the
machine or motor shaft, where it is mounted.
NOTE
The ROTOMEC couplings, whose shafts bore are in inches, will be equipped
with grub screw for axial fastening on the shaft, as an alternative to the axial fixing
screw.
4.2.5 - SHAFT ASSEMBLY WITH TAPER SLEEVE
To fit the coupling on shaft with taper sleeve, proceed as follows:
4.2.5a
In order to fit hydromechanic couplings with taper sleeves without key-
way, remove feather key from drive shaft/reduction gear.
4.2.5b
Accurately clean with a neutral detergent all the contact surfaces
between shaft, sleeve and taper hole.
4.2.5c
Position the sleeve using a retainer (to be removed after tightening the
retaining screw on shaft end).
NOTE
The length of the closely fitted shaft must be lower than the taper hole
depth and have a threaded bore on the top.
4.2.5d
For couplings with weight over 30 kg, fully unscrew and remove one of
the screws of coupling shell closure and insert a suitable WESTCAR hoisting
device (available on request).
