Just so you know that picture is of a 4 cylinder BMW, Saab, Audi, or Volkswagon CIS unit. This one pictured has an airflow meter that swings upwards and the opposite direction to the one on a 930.
It's also missing alot of fuel head parts in this diagram/picture and the diaphram and orifice's are different than a USA lambda head but it's better than nothing.

I've never heard of anyone trying to lubricate the pivot bearings on the airflow sensor arm. Some people probably have and you could spray something thin like WD40 with the long straw attachment at them from the inside.
I wouldn't try to remove the circlips and covers over the bearings on the outside.

It would be very difficult to see what you're doing while the airflow housing is installed on the motor.
If all the fuel lines are off the fuel head than there's only 3 - 13mm nuts holding the housing onto the intake manifold and 3 screws hold the fuel head onto the housing.
If you use spray lube at the bearings, taking the fuel head off may be the best way to reach them.
