Installation and operating instructions Wilo-CronoLine-IL, CronoTwin-DL, CronoBloc-BL
• Install the new motor with suitable hoisting gear and screw the lan-
tern/motor (and adapter ring for BL pumps) connection together.
• Check the coupling and shaft sliding surfaces. If necessary, clean and
lightly oil them.
• Pre-install coupling shells on the shafts with shims inserted in
between them.
• Slide the forked spacer (Fig. 19, item 10) between the lantern and
coupling. The forked spacer must sit there without any play.
• First, slightly tighten the coupling screws until the coupling half-
shells are in contact with the shims.
• Afterwards, screw the coupling together evenly. In doing so,
the specified distance between the lantern and the coupling of 5 mm
is automatically adjusted via the forked spacer.
• Remove the forked spacer.
• Install the coupling guard.
• Connect the motor cable or mains connection cable.
Pump type design C:
• Loosen the lantern fastening screws (Fig. 6, item 4) and lift the drive
with lantern unit (coupling, shaft, mechanical seal, impeller) off the
pump with suitable hoisting gear.
• Loosen the impeller fixation nut (Fig. 6, item 1.11), remove the coni-
cal spring washer (Fig. 6, item 1.12) beneath it and pull the impeller
(Fig. 6, item 1.13) off the pump shaft.
• Dismantle the shim (Fig. 6
,
(Fig. 6 item 1.43).
• Pull the mechanical seal (Fig. 6, item 1.21) off the shaft.
• Loosen the motor fastening screws (Fig. 6, item 5) on the motor
flange and lift the lantern off with suitable hoisting gear.
• Loosen the coupling screws (Fig. 6, item 1.44).
• Release the shaft (Fig. 6, item 1.41) from the motor shaft.
• Thoroughly clean the sliding/seat surfaces of the shaft. If the shaft is
damaged, it must be replaced.
• Slide shaft (Fig. 6, item 1.41) onto the new motor up to the stop.
• Tighten the coupling screws (Fig. 6, item 1.44).
• Mount the lantern with suitable hoisting gear and tighten the motor
fastening screws (Fig. 6, item 5).
• Pull a new mechanical seal onto the shaft. A commercially available
dishwashing liquid can be used as a lubricant (if required, insert the
key and the shim again).
• Install the impeller with washer(s) and nut, countering at the impel-
ler's outer diameter while doing so. Avoid damage to the mechanical
seal due to jamming.
• Slowly insert the drive with lantern unit (coupling, shaft mechanical
seal, impeller) into the pump housing using suitable hoisting gear and
screw it into place.
• Install the coupling guard.
• Connect the motor cable or mains connection cable.
