ZF Hurth 220A Oil change questions
For those of you who have this transmission, do you drain the oil through the dipstick hole or is there a drain plug and, if there is, where is it located? I see two largish hex plugs on the bottom of the aft part of the transmission. Is one of these for draining oil? I have been draining through the dipstick, which is a pain, but I'd like to rig up a permanent oil drain hose arrangement as is on our main engine (Cummins 6BTA) and on our Westerbeke 5.0kw BCDB generator.
Also, is there an oil filter on the ZF 220A? I don't see one and I don't think that there is one, but I want to be sure I am not overlooking a maintenance item.
