Changing oil in differential 1923 Super Six

rhurst

Changing out the oil in the differential of my 1923 Super 6. Using the recommended 600wt but it goes in very slowly.

I removed the inspection plug in order to let the air out and got a little better flow. Does anyone know

how many ounces that it takes to fill the rear end? I'm going on the second day of filling it.

I cleaned out the intake pipe as it had a 90 degree turn and a lot of old oil maybe 98 years old seemed to block the entry.  I have put in 1qt, does anyone know how much it

takes?  1923 Hudson Super 6.

Glove box manual says - keep filled to lower level of over flow plug in rear cover

Yep that's just what I did.  Put in 3 Qt's It's happy now and the wheels turn easier!
