5.4 - Shrink-disc Ot 3233 to Ot 3533
5.4.1 - Mounting
Remove all grease from shaft and hollow shaft bore.
1 - Lightly oil the seating of the shrink-disc on the hollow shaft.
2 - Draw shrink-disc onto hollow shaft. Slide shaft and hollow
shaft into one another.
3 - Tighten diametrically opposed clamping screws by hand
whilst aligning the shrink-disc so that the clamping flanges lie
parallel to each other.
Tighten the clamping screws one by one with a torque wrench to
tightening torque. Repeat several times. The tightening process
is only finished when none of the screws can be turned any
further. (Refer the tightening torque indicated in Chart.)
Tightening torque for bolts of shrink-disc
Dismantling
1 - Part-release the clamping screws evenly in stages in order to
avoid any tilting of the clamping flanges whilst taking great care
for safety reasons that the clamping screws are not completely
released from the thread bore as the pretensions in the shrink-
disc could cause the discs to jump apart.
2 - Draw the shrink-disc off the hollow shaft, and if applicable,
clean oxidizing on shaft and hollow shaft bore.

All the bolts must be screwed up to 70% of their
elastic strength.

5.6 - Hollow shaft

1 - Check that the cylindrical shaft has been machined in
accordance with standard NF - E 22 - 175, with a slide fit: g6, (the
hub is: H7).
2 - Check that the key is standard and the shaft is the minimum
length tapped at the end (O.Z).
3 - Before mounting, degrease all the parts, taking care not to
splash any solvent on the seals.
Use grease (PAO compound) to lubricate any parts in contact, to
avoid corrosion.

5.5.3 - Torque arm mounting

Screw the torque arm (17) on the fixing side by using screws
(195). Centre torque arm. Place the pin.
The screws must be stopped by an anaerobic adhesive (Loctite
Freinfilet normal 243 for example). This adhesive must resist to
vibrations and may allow dismounting of torque arm if necessary.
Braking torque of fixing screws
Tighten screws simultaneously and progressively.
Mounting
O ring seal
Mounting should be performed as described in the procedure
above, without jolting.
The Ot gearbox is mounted on the machine shaft using a
threaded rod, screwed into the shaft.
By screwing the nut down onto the washer, the shaft is smoothly
inserted into the cylindrical hub.
Dismantling
O ring seal
Use a spanner with a diameter corresponding to the shaft thread
and turn until the shaft comes out.
