7 MAINTENANCE
This section describes the recommended maintenance procedures to ensure maximum
performance and a long lifetime of the 2AP GD. Regular lubrication of a Gear Drive is necessary to
prevent severe damage to the gears. Periodically check the condition of all cables and connectors.
Important: Gear Drive lubrication
The worm/spur gear drive for both the azimuth and zenith shafts should be lubricated twice annually
if possible. It is recommended that a lubrication be carried out in the autumn (fall) season to provide
sufficient lubrication during the possible extreme cold condition of the winter months.
Tools required:
• Standard hand-pump grease gun with flexible hose (minimum 15 cm).
• Lubricant: Aero Shell Grease #17 (Kipp & Zonen art. no. 8550765).
Important: Lubrication type
Aero Shell Grease #17 is the recommended lubricant to meet the requirements for adequate
worm/spur gear lubrication. Do NOT mix different grease types! Contact Kipp & Zonen if this
lubricant is not available in your area or if you require more information.
The Azimuth worm housing grease fittings (x2) are accessible from the top of the 2AP and the
Zenith worm housing grease fittings (x2) are accessible from the rear, see figure 7.1.
Lubrication procedure:
• Pump 1-2 ounces (30-60 g) of lubricant into each grease fitting.
• Clean any large amounts of excess grease off the brass gears and the outside of the worm
housing to avoid having the grease fall off during operation and come into contact with other
components inside the 2AP.
