OPERA TION ANO MAINTENANCE
3.1 The normal operaling procedures have lo be carried on
keeping balance and temperature under control.
l\jol 10 damage Ihe coupling seals, lemperalure musl no!
overcome 90'C. For hlgher values, all Ihe seals bul Ihe rolaling
ones In Viton (items 15 and 20), have lo be made of a special
material 100.
As eVldenced in TAB. F where the causes and the relalive
remedies are reported, a high temperature value may be
caused by the following condillons:
a) Insufficlenl oil fill
b) Higher absorbed power Ihan motor rated power
C) HIgli Clmbíenl lemperature
d) High starting frequency per hour
e) Excesslve slartlng time
f) Too many consecutive start-ups
g)
Inadequate aír ventilation due to cover guardo
TRANSFLUID can supply all operating
data upon request.
3.2 After the first 20 days operalion, check the
oil fill (this operation to be carried out
with cold oil), the tightening of the screws,
the molor and the driven machine.
3.3 Repeal Ihe above checks every 6 months
-
For the KRG models, check the gap K
(TAS. C) of the elastic coupling. If the
torsional gap is excessive (about 2°),
replace the rubber elements.
3.4 Fluid couplings are supplied with fusible
plug al 145"C (120°C, 175°C and 198°C
settíngs are available upon request) as
shown in FIG. 14.
If the fusible plug blows al regular intervals
during normal service, then checks a), f) in
par. 3.1, and relalive T AS. F should be
considered.
3.5 In case the switching pin or the electronic
overload controller are mounted, check
that the dístances shown in FIG. 9 and 11
are wilhin the values imposed during the
assembly phase.
3,6 Oil should be replaced after 4000 hours
operation.

4.1 Disassemble lile fixing screw (ilem 25 for I<R models; ilem 26
tor KSD models).
4.2 Screw threaded bal In10 tapped hole al Ihe em! of tlle iluld
coupllng and proceed as shown in FIG. 8 The said tllreaded
bar (dimensions Q reported in TAS. G) will pusl-I the coupling
off the molor sllaft.
4.3 For Ihe couplings assembled witll a laper bush, a very small
displacemenl is sufficienl to disengage the coupling from ItS
sea!. In case the laper bush is to be removed 100, a
screwdriver may be used to push inlo the keyway cut.
Do nol force into the taper bush to avoid damaging the
contact surfaces and then compromise the correct
reassembly of the par!.
