General Assembly; Technical Data - Vetus Bullflex Installation Instructions Manual

General assembly

LOCTITE 270 Studlock
To achieve a reliably
operating coupling
all the bolts and nuts
must be tightened
with the torques
given. Use a torque
wrench; tightening it
'in the blind' will not
lead to satisfying
results.
The propeller shaft
must be inserted into
the hub for a suffi-
cient length (L) and
the shaft and hub
must be free of
grease and dirt (*).
