Re-lubricating the Taconite seals
The grease nipples of the Taconite seals must be filled with grease until clean grease emerges
from the grease gap. Remove and dispose of escaping grease. Recommended grease: Petamo
GHY 133N (see Section 6.2: Klüber Lubrication).
Note!
Optimal re-lubrication is achieved by rotating the gear unit shaft in 45° steps when lubricating
and pressing in grease until clean grease emerges from the shaft.
Checking fans for dirt
The inlet and outlet openings on the fan cover and the fan wheel must be kept clean.
Danger!
High pressure washers and compressed air must not be used for cleaning, as particles
or water may enter the gear unit.
Danger!
Before recommissioning, observe the notes in Section 4.4.
Changing the oil
The figures in Section 6.1 show the oil drain screw, the oil level screw and the pressure vent
screw for various designs.
Procedure:
1.
Place a catchment vessel under the oil drain screw or the oil drain cock.
2.
Completely remove oil level screw, screwed sealing plug with dipstick if an oil level tank
is being used and oil drain screw.
Danger!
Warning: Hot oil!
3.
Drain all the oil from the gear unit.
4.
If the screw lock coating of the oil drain screw or oil level screw is damaged in the
thread, a new oil level screw must be used or the thread cleaned and coated with
securing lubricant, e.g. Loctite 242, Loxeal 54-03 prior to inserting. The seal ring must be
replaced if damaged.
5.
Support the seal ring, insert the oil drain screw into the hole and tighten to the correct
torque! (See Chapter 6.4 for torque values)
6.
Using a suitable filling device, refill with oil of the same type through the oil level hole
until oil emerges from the oil level hole. (The oil can also be filled through the pressure
vent screw or a sealing plug located higher than the oil level). If an oil level vessel is
used, fill the oil through the upper inlet (thread G1¼) until the oil level is set as described
in Section 5.2.
