1.2
Fm KRG model, remove hall coupling G (Ilem 29
- FIG. 4):
For KRD model, disassemble
shaft D (item 31
- FIG. 1b). In case fhe fluid coupling
is stHI filled with oil, drain it or, to avoid possible
losses, position it vertically
with lhe shalt D upwards;
alter disassembling
the shaft D, block the bearing carrier (item 14) with at least 2
nuts and washers
(item 11 and 12),
Check that the threaded
hole at the end of the motm 01'gearbox shalt complies with DIN 332 (TAB. A1-A2 and FIG. 4),
1,3
a) without
taper bush
1A.a
Fit the coupllng
on the motor shaft by using a threaded
bar
with S dia. (TAB.
A 1 and A2) as shown
in
FIG. 1a, and
using 2 wrenches
(hold
a to avoid shaft rotatlon, and tum b
to draw the coupling on to the motm shalt),
1,5.a
For a correcl
assembly,
lubricate
the connecting
surfaces
wlth
oil 01' antiseizlng
paste,
For hot mouniing
(not
recommended),
do not overcome
a temperature
of 90°C,
Wllich causes Irreparable
damages to oil seals,
b) with taper bush
1.4.
In
case the bush is not provided with keyway (ílem 50 or 51
-
FIG. 1b), remove
the key from motor
or gearbox
shaft
(reverse mounting).
1.5.b
Carefully clean all surfaces contacting
the bush by oil,
grease, etc., possibly
usmg solvent,
whether they belong to
motor, gearbox 01'fluid coupling.
1.6.b
Fit the bush on the motor or gearbox
shaft,
intoducing
a
screwdriver
into the axial cut to make
mounting
easier;
assure that bush goes as far as the shaft shoulder.
For KRG series, fit half coupling (item 29
-
FIG. 4) on driven shaft, taking care that the shaft end does not protrude beyond face X.
Fit the fixing screw and the washer (items 25 and 26 for KR models;
items 26 and 27 for KSD models) holding the motor or the gearbox
shaft still; lock
the fixing screw with a torque
wrench,
respecting the torque reported in TAB. A 1 and A2.
Only for
13/15
KR
KSD
models (FIG. 3): fit the allan screw (item d) with flat washer (item e). Holding the motor or gearbox
shaft
with a 38 mm wrench b 01'1 the end c, lock the allan screw with a torque wrench a, respecting
the torque reported in TAB. A2.
N.B.:
For a correct
assembly
with the taper
bush,
strictly
apply
to the prescribed
locking
torque.

1.8
For KRG models,
lock and peg the driven machine,
positioning
the motor as far as the gap K (FIG. 4) between
the half couplings
reaches
the Indicated
values
listed in TAB. C.
The error on radius can be checked
with a gauge and a straight-edge
(FIG. 4): the
angular gap with a feeler, by rotating the coupling at 4 points 90° apart: the errors should not exceed those listed in TAB. C.
Fm KRD model, reassemble
shaft D by locking nuts and washers (items 11 and 12 - FIG. 1b) at the prescribed
torque (TAB. B).
