5.1.3 - Shaft mounting
Mount the torque arm with bolts of at least class 8.8 tightened to a torque of 70% of their failure stress. Clean
and degrease both the internal coupling surface of the gear unit shaft and the external coupling surface of
the machine’s driven shaft.
Mount the shrink disk to the gear unit’s shaft after lightly lubricating its entire
outer surface . Snug down a
first set of 3 bolts located at the corners of an equilateral triangle (for example: bolts in pos. 1-5-9 of the dia-
gram below). Fit the gear unit to the driven shaft.
Tighten down the bolts (following the triangular pattern) in a circular direction, repeating the operation seve-
ral times until all bolts are tightened to the torque specified in chart 2, in accordance with the type of
disk/gear unit.
N.B.: Do not tighten down diametrically opposed bolts in sequence.

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.
