Hi all,

I have a 1955 2nd series 6400. It has the two speed rear axle. I am trying to clean and prep for painting. I would like to drain the oil out, clean the sludge and refill the oil, however, I am a bit confused on how to go about it. I do not find a typical drain hole on it. I have read some posts to remove the bottom bolt from the cover plate and drain through that. But then how do I refill and to what level? Any tips and pictures would be a great help.
