1 Measure the inner diameter of the propel-
ler shaft in the vicinity of the oil inlet
flange. Dimension. See also section 72-
10-00 Wear limits.
NOTE: It is not the dimensions GB05 or
GB06 which are important, but
the backlash GB05/GB06.
2 Check the propeller shaft for cracks. See
section 00-00-00.
The results of the magnetic particle
crack check must be entered in the form

Treatment of corrosion damage and surface da-
mage on the propeller flange.
See Fig. 13.
The flange of the propeller shaft is susceptible to
flash rust. After the propeller shaft has been
covered with an adhesive plastic tape or a plas-
tic tube, the propeller flange can be treated with
a blasting medium.
NOTICE
WARNUNG
To apply the protective paint, carefully cover the
flange surface, fastening bores and the pro-
peller shaft.
To prevent corrosion damage, the rear of the
propeller flange should be coated with a layer of
anti-corrosion paint.
In the event of more severe corrosion damage
which has affected the material, the propeller
shaft must be replaced.
