8.4
Replace bearings
The bearing service life depends greatly on the operating conditions and so cannot be
calculated reliably. In the operating conditions specified by the operator, bearing life can be
calculated and indicated on the rating plate. If no information is given, changes in vibration
and noise pattern can serve as an indicator that an immediate bearing replacement is
necessary.
8.5
Checking the gearbox for leaks
Note
From the inherent principle of operation, oil mist can escape from the vent valve or a
labyrinth seal.
Oil or grease escaping in small quantities from the shaft sealing ring should be regarded as
normal during the running-in phase of 24 hours operating time.
If the quantities escaping are significant or leaking continues after the running-in phase, the
shaft sealing ring must be replaced to prevent consequential damage.

Film of moisture
on the shaft seal-
ing ring
Film of moisture as a
result of the inherent
principle of operation
(apparent leakage)
Remove using a clean
cloth and continue to
observe.
This does not represent a
fault; frequently, in the
course of operation, the
sealing ring dries off.
Leakage at the
shaft sealing ring
Identifiable small trick-
le, formation of drops,
also after the running-
in phase
Replace the sealing
ring, determine the
possible cause of the
sealing ring failure and
rectify.
During the run-in period, the
shaft sealing ring beds into
the shaft. A visible track can
be seen on the shaft. Opti-
mum preconditions for a
perfect seal are obtained
after the run-in period.
8.6
Replacing the vent valve
To ensure correct functioning, renew the breather valve yearly.
When replacing, prevent dirt and damaging atmospheres from entering the gearbox.
If too much oil is contained in the gearbox, oil will escape from the breather valve. Correct
the oil quantity and replace the breather valve.
