1966 DIESEL CASE 530 CK ISSUE?

[southernbound]

Hi folks- My issue is I've drained all fluids and replaced with high dollar case fluids..My question is I've refilled the torque tube and hydraulic reservoir through the breather next to the shuttle shift. I now have NO reading whatsoever on the dip stick?? I'm lost... Everything I've read told me it was ok to fill through the breather. Is there another fill? I'm looking at lube recommendations and it says with a torque tube and hydraulic reservoir in holds 12 quarts. Is this correct?

I got some pics..I know the differential plug but wanted to give a btter idea of what I'm working with. Is the plug on the right side in picture my actual fill for torque converter area? Can I just fill through breather like I did?

So....like a complete DUMB*SS I was pouring my 5 gal pale of hy-tran in a 1 gall bucket I put marks on at 2 quarts/4quarts....In my confusion of adding oil frustrated I did'nt know where the correct fill plug was I thought I marked 4/8 quarts..I now added correct amount of hy-tran and it reads fine..haHAHA.. If it was not for the stopping to go for beer I'm not sure I'd of realized what I did... Gotta love beer.
Still would like to know if the 1'' plug in pic is the correct fill though
