Case 530 tractor....has what looks like a filler plug but what goes in it, if anything at all? I don't have a picture from my tractor...so here's an attachment from the Case Parts websight. What is #29? I see 17 is a drain plug...so does any type of fluid supposed to go in there or what? That's housing is where the torque converter goes. I don't think any fluid is suppossed to go in this area...because the case websight is calling #29 a "nut breather tube cover" 21 says it is a "plug drain and timing hole". That leads me to believe that nothing goes in there. Just want to ask questions to be sure as I am not a mechanic per say.
