ƒ Before mounting the second bearing on the shaft
push in the circlip (932.51) between the two bear-
ings.
ƒ Before mounting new bearings, warm them up to
80°C in an oil bath or using a bearing heater. If
necessary use a tube to force the inner ring onto
the shaft by gentle taps with a hammer. Hold the
outer ring to avoid vibrations of the balls.
ƒ When bolting together the bearing bracket (330)
with the bearing bracket lantern (344) and the
bearing bracket lantern with the volute casing
(102V), screws should be positioned in the centre
of the drilled holes. Failure to do so could result in
improper oil setting.
ƒ Push the flinger (507) onto the shaft (210) till it
rests axially against the shoulder of the shaft. Be-
tween flinger (507) and Bearing bracket lantern
(344) there must remain a clearance of at least
0,7 mm.
ƒ If necessary you can use a driver for mounting
(see picture 14).

ƒ Do not use excessive force.
ƒ For mounting of the shaft sealing (packing or me-
chanical sealing) see separate description
"Mounting Instruction of Shaft Sealing" and chap-
ter 8.5.
ƒ For impellers with back vanes the axial clearance
between the back vanes and the casing cover
(161) should be checked after mounting the im-
peller (230) and tightening the impeller nut (922)
(see chapter 8.7.1).
ƒ After the mounting of the back pull out assembly,
and its assembly into the volute casing, turn the
shaft and control the free moving of the pump in
this way. The shaft sealings will cause slightly re-
sistance when turning, but there must not be any
contact between metal parts.
ƒ
Before starting the pump check alignment of the
coupling. This can be dropped on pumps with
spacer coupling, if pump casing and motor were
not disassembled.
Before starting the pump do not forget to fill in
oil!
Before starting the pump do not forget to install
and connect all security devices.

To ensure optimum availability, we recommend
that suitable quantities of spare parts are held
in stock, especially if these are made from spe-
cial materials and in the case of mechanical
seals, because of the longer delivery times.
