Pump Oil Changes

[Kirb]

How often do you chance your oil in IBA, SS, and compressor pumps?

How high in the sight window should the oil be? I have been keeping it just above the dot so about 5/8 to 3/4 of window is filled, but not sure if this is to high and could cause possible damage.


Thanks,
Kirb

I change yearly in the fall.. If you have a sight glass with a dot , just keep it to the center of the dot(that is considered full)..

I change every 6 months. In the Fall, then again in the Spring.
