How much oil?

[bobsusancart]

Found the fill hole, rubber plug on driver side of differential, about 1 inch in dia and 2 inches above the axle, cart guy local says fill til it over flows. I think that may be too much oil because there's a bolt on top of the axle on the passenger side that drips oil so I think you remove that bolt and fill til that overflows. I think mine is missing the gasket (small fiber washer?) on the bolt and that explains the drip, or maybe I'm the drip...

After cleaning the differential housing I found that all the bolts there are not to hold the housing together, one on the driver side has a rubber gasket, that's probably the fill line and on the passenger side much lower is another with a gasket, that's probably the drain. After inspecting the bolt on top of the axle on the passenger side I found that it has a drilling so it's probably an expansion vent. All this was hidden by dirt and oil mixed all over the diff housing and axle. Hopefully I'm ready to go now. Replied to my own question? Part of the learning curve.
