I am starting to work on this 8n 1950 ford I bought last fall. Its been sitting outside for a long time. I decided to drain the oil from the rear end, hydraulics and transmission. I have checked on here and if I am correct you fill all three of these departments through the filler cap by the shifter with a side plug on the transmission to check the level at an amount of 5 gallons to fill all three compartments. Is this correct or am I missing something. So far there wasn't any water in the oil. since it is missing the dip stick for the hydraulic reservoir im surprised. I have changed the oil and filter in the motor. installed new plugs. Removed the rear wheels. Brakes on both sides seems to work fine. I don't have any manuals so I will be looking for some downloads if there out there or try to buy them off the internet. All help and comments welcome as I am new to the 8n fords. thanks Norm
