Measure distance „b“ from the elastic element face to the seat-
ing area of ange (106-12).
Dierence in the distances a - b = 1 ÷ 3 mm.
Colored (e. g. blue color) material is deposited on the thread
of the supplied countersunk hexagonal screws. Such material
includes a lm of adhesive and prevents its releasing. The time
of hardening of such adhesive material after screwing the bolts
is 4 ÷ 5 hours at the ambient temperature of 20 °C. The opera-
tion of the machine should not start before this time period
has elapsed. Full hardening is nished after 24 hours. At higher
temperatures the hardening can be faster, e. g. 15 minutes at
70 °C (heating performed by a hot air fan). Temperature stability
of the bolts is between -80 ÷ +90 °C (-112÷ +194 °F) and they
can be used three times at maximum. The adhesive material is
sometimes wiped o and it is deposited between the head of
the bolt and the segment. This is not a defect, rather advantage
- both areas will adhere to each other better. If original supplied
bolts are not available, both the bored thread and bolt must be
carefully degreased and a layer of Loctite or Omnit should be
applied to them.
Spring washers are not allowed!
The tandem of hydraulic generators including the connection of
hydraulic hoses and electrical wiring should be installed using
a crane in the opposite way.
