MZ52 Hydros Maintenance

[cpurvis]

Trying to change the oil and filters. I got a lot more oil out than I've put back in.

The sketchy info in the owner's manual says to remove (or was it loosen?) the vent plug (see illustration) but there is no callout in the illustration. All kinds of info about how to dispose of the filters, though.

It has the 3100 hydros with a single reservoir.

If you've done one of these, I'd appreciate hearing how you refilled the hydros.

Thanks!

Is it possible to get the air out of a hydro if you can't open the vent plug?

I've got about 3 1/8th quarts in now; book says it should take four quarts to fill both hydros to the vent plugs.

Wonder if that's enough to proceed to the bleed process?
