Clean and degrease both the internal coupling surface of the gear unit shaft and the external cou-
pling surface of the machine’s driven shaft.
Mount the shrink disk to the gear unit’s shaft after lightly lubricating its entire outer surface.
Mounting sequence for shrink discs with gear units sizes 300-313 , 310M-313M
• Snug down a rst set of 3 bolts located at the corners of an equilateral triangle (for example:
bolts in pos. 1-5-9 of the diagram below). Fit the gear unit to the driven shaft.
• Tighten down the bolts (following the triangular pattern) in a circular direction, repeating the op-
eration several times until all bolts are tightened to the torque specied in table 2, in accordance
with the type of disk/gear unit.
Mounting sequence for shrink discs with gear units sizes 314-325 , 314M-318M
• Tighten 4 screws equally spaced at 50% of the value of the tightening torque indicated in table 2,
crosswise. (example: screws 1-7-4-10)
• Tighten 4 screws equally spaced at 100% of the value of the tightening torque indicated in table
2, crosswise. (example: screws 2-8-5-11)
• Tighten all the screws continuously up to the point that, by applying the tightening torque indicat-
ed in table 2, these no longer have any movement.
• Check the effective alignment of the inner and outer ring of the coupling.
Do not use molybdenum bisulphide or any other grease, which could reduce the friction of
the mating surfaces and affect the performance of the shrink disk.
Proceed with the installation as follows:
1. Place the gear unit in the vicinity of the installation area.
2.
Mount the gear unit and secure it to the structure at the points provided. The gear unit should be
secured to the structure at all the mounting points (bores) on the mount provided (feet or ange).
3. Tighten down the mounting bolts and check that the service plugs are screwed down to the
torques given in the chart.
