♦
Press the bellows collar out of the guide of the
thrust flanges and then screw the bellows
206
off
the spindle
802
.
♦
Assemble the entire upper section (without
bellows) again with the body
100
.
♦
Screw hex. nut onto the threaded rod (up to flange
contact with spring bonnet
513
).
♦
Screw hex. nuts onto both ends of the threaded
rods and counter with more hex. nuts.
♦
Tighten adjusting screw
538
(turn into the spring
bonnet
513
) until the spacer sleeve is loose.
♦
Undo hex. nuts at the end of the spindle and also
remove spacer sleeve.
♦
Undo adjusting screw
538
and screw it out of the
spring bonnet
513
.
♦
The pressure spring 952/1 is only partially
relieved in this situation.
♦
In order to completely relieve the spring, the two
nuts per threaded rod are evenly turned upwards
until the spring bonnet is loose.
It is imperative to secure the threaded
rods against turning (turning out of the
body flange) with a wrench on the
counter nut
–
Risk of accident!

♦
Assembly
the complete upper section with its
internals without the bellows
206
, plug
204
and
lifting aid
237
.
♦
Grease the outside thread of the adjusting screw
and the inside thread in the spring bonnet (for
adjusting screw) well and, if difficult to screw, also
spray with torsion spray.
♦
Mount a hex. nut on the free end of the spindle so
that when the complete unit is raised the internals
are held and they do not fall down. See
Fig. 21.

Tighten spring bonnet
513
with hex. nuts until they
sit tightly on the body
100
. See
