Fasten both thrust nuts
0140b
and
0140c
to the collar
of the straining screw
0140a
. Beforehand, apply some
of the lubricant “DRY FLUID HELI” onto the threads.
(has already been done before delivered). The
lubrication is indispensable (shake well before use).
Otherwise the threads will damage upon clamping
under pressure.
Attention!
The nut
0140b
with a single mark has a right-
hand thread. The nut with two marks has a left-hand
thread. There are no markings on the straining screw.
Find the matching threads by careful insertion.
Preferably start with nut
0140b
(right-hand thread). This
will conclude the left-hand turns on the opposite side.
(note the direction arrows). The milled grooves of both
nuts need to be perfectly aligned by slightly unscrewing
one of the nuts. A slight difference between both gaps
to the collar is irrelevant.
