Removing
Do not completely remove fastening screws before locking rings are disengaged.
Risk of serious injury!!!
Clean off any rusty areas.
Loosen the fastening screws one after the other only by using approx. ½ turn at a time and by a continuous
sequence (not crossing), until shrink disc can be moved on the hollow shaft.
Remove the customer shaft or the gear reducer. For sizes above 030A to make it easier is possible to inject
low pressure oil through a threaded hole located on the hollow shaft (see below).
"T" outputs can be used for gear reducer shaft mounting on solid splined shaft end and on solid splined gear
wheel flange.
For the assembly of "T" output to a solid splined gear flange consider the following instructions:
– disassemble the metal plugs on splined gear holes pre-arranged for the half-ring fastening screws.
– lubricate carefully the splined shaft surfaces with grease for industrial applications with heavy loads and
long lasting
– insert the O-ring seal on the flange shaft
– in case of mounting with wheel flange: orientate the accessory before mounting; identify the tooth of
splined shaft timing with the relevant recess positioned on gear reducer shaft. Timed tooth and recess are
identified as per hole see sketch below.
– insert slowly the splined shaft so that air can flow out
– assemble radially the cover compressing the O-ring.
– screw with cross tightening the half-ring fastening screws taking care to tighten to relevant torque.
– close the splined gear flange using plugs
