FAQ

Do you have questions about the Hansen P4 UniMiner Gear Unit? Below are some of our most commonly asked questions, or you can view our Support area under Knowledge for more frequently asked questions and answers.

What type of lubrication method does the P4 use?

Hansen P4 units use one of the following systems:

Splash Lubrication (standard with horizontal shaft gear units for speeds between 750 and 1800RPM at the high speed shaft. Gears and output shaft bearings are lubricated by immersion in the oil bath. Oil splash from gears fill the oil pockets in the housing, assuring gravity circulation lubrication of the bearings via channels in the housing and covers.)
Force Feed Lubrication (all rotating elements above oil bath level are lubricated by a gear pump forcing the oil through pressure lines. Forced feed lubrication is available as circulation lubrication or pressure lubrication.

What type of lubrication should be used?

Mineral oils containing EP additives, which increase oil film load capacity should be used. Refer to the P4 service manual for recommended oil types.

How often do I change the oil?

The first oil change should be carried out preferably after 100 hours and not more than 800 hours of operation. The removed oil may be used again after filtering. Filter the oil volume at least 10 times using a 10mm filter or smaller. Subsequently the oil should be renewed after 4000 to 8000 hours or maximum of 18 months of operation depending on working conditions. Please refer to service manual for detailed oil change instructions.
