7.4.6. Shaft assembly removal
Pumps Size 0:
•
Remove the key (61A) from the driveshaft (05).
• Remove the screws (51C) and dismount the rear cover (12B) while
checking that the O-ring (80E) does not stick to both sides.
Pumps Size 1, 2, 3, 4:
• Identify the position of the driveshaft (05) and whether it is in the
left or right position.
• Remove the screws (52) – the screws (51D) at pump size 1 - and
washers (53A) that fix the bearings cover (12) to the gear case (06).
• Remove the key (61A) from the driveshaft (05).
• Remove the shaft assembly from the gear case. Due to the tightness
of the bearings cover (12), a Nylon hammer must be used. Lightly
tap the rear part of the driveshaft (05).
• Check the condition of the Klingerit seal (18A) once the shaft
assembly has been removed, and if there are any defects, find a
replacement before reassembling the pump.
