Installation:
1.
Carefully slide the screw spindles (imperative in pairs) onto the shafts. The left-hand spindle
will then be located on the driver shaft (long shaft) and the right-hand spindle on the driven
shaft. Observe correct seat of the O-rings when sliding the spindle onto the seal.
2.
Insert O-ring 2194 into the greased groove of the spindle nuts.
3.
Screw in spindle nuts on both shafts and slightly tighten alternating, manually at first, then
using an open-end spanner. In this process, just hold shafts and spindles in place manually.
•
The seals are prestressed when slightly tightening the spindle nuts. Check to
see that exterior stator 1A is slowly pushed into the seal housing against its
spring.
4.
Tighten the spindle nut on the driving shaft (long shaft) while holding the shaft in place in the
drive shaft with the steel mandrel inserted in the hole. Torque = 150 Nm.
5.
Tighten driven shaft spindle nut using torque of 150 Nm and block the shaft by inserting a
wedge made from soft material (aluminium or copper).
6.
Let pump housing 1033 slide into the dowel pins via the screw spindles, insert and tighten
screws 1016 with washers 1015 via the bearing housing.
7.
Further pump assembly in reverse order.
Possible damage to property
•
Carefully slide the screw spindles together onto the shafts.
•
Before screwing in the spindle screws, wet both threads on the spindle screws with a
thread-locking compound (factory uses Loctite 270).
•
Observe the required tightening torques (Chapter 4)
•
When replacing screw spindles, you will also need to synchronize them via the pinion gear
drives (see Chapter 9.6)
