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 m
ist can escape from the vent valve or a
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.

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.
