If through-holes ( flange B5) are used for fastening, carefully select the length of the fastening screws, which must be long enough
to ensure a sufficiently extended clamping section to ensure correct fastening of the gearbox to the machine.
Before tightening the bolt be sure that the eventual centering of fl anges is inserted properly
Screws must be tightened diagonally with the maximum torque indicated in Table 5.2.1.
In the fastening screws and in the fl ange mating surfaces use
locking adhesives.
