BA 5060 EN 04/2011
In case of gear units fitted with forced lubrication or an oilcooling system, the oil circuit must
also be charged with oil. To do this, briefly start up the gear unit with the addon pump
(observing the description in section 8).
• Screw in the oil dipstick or plug screw.
• Check the oil level in the gearunit housing with the oil dipstick screwed in and/or by means of the
oilsight glass.
When the oil is cool, the oil level should be at the upper mark on the oil dipstick screwed in.
When the oil is warm it may slightly exceed this mark. It must in no case be allowed to fall below
the mark. If necessary, top up to the correct level. The greaselubricated output bearing is
protected by an oildam pipe from oil (see item 5.6.2).
Any oil spillage must be removed immediately with an oilbinding agent.
7.1.2.1 Oil quantities
The oil quantity is indicated on the rating plate fitted to the gear unit.
7.1.2.2 Greaselubricated rolling bearing
The gear unit is delivered ex works with the necessary grease charge for the lower outputshaft
bearing.

A detailed view of the gear unit can be obtained from the drawings in the gearunit documentation.
For longer periods of storage (> 6 months) in a situation which is different from the mounting position,
a corresponding quantity of grease (see table 9) should be repacked using a grease gun prior to initial
operation. For the correct type of grease, refer to the table "T7300" (for a link, see the BA 7300 document
supplied separately).

If the gear unit has not been in use for more than 36 months or if the lower outputshaft bearing has been
inspected or renewed, the bearing space must be filled with the amount of rollingbearing grease specified
in table 10. For the correct type of grease, refer to the table "T7300" (for a link, see the BA 7300 document
supplied separately).
