Oil quantity and oil level check
Oil cooling tubes
An oil level gauge is supplied together with the seal kit and must be screwed into one of two tapped holes in the housing base positioned on the opposite side of the oil pick-up ring († fig. 1). Minimum and max imum oil levels are marked on the gauge. Required oil quantities are provided in table 1. Information about the space required by the oil level gauge is listed in table 3 on page 19 as well as in the product tables. If oil is added to the housing during oper ation, keep the level 5 mm below the max imum mark.
In high temperature applications where an oil pick-up ring is used, an auxiliary cooling tube should be used. These are available in different sizes and can be installed via the oil outlet holes in the housing base († table 2). They are available in different sizes. One or two of them can be installed via the oil outlet holes in one housing base († fig. 2). Detailed mounting instructions can be found on page 26. Oil cooling tubes are identified by the basic designation AVA-0001 followed by a size identification, e.g. AVA-0001/3.

Oil outlet Tapped holes in the housing base that are not used for the oil level gauge, the magnetic plug or cooling cartridges can be used as oil outlets.
