Hi, I need some help with the transmission oil in my 1952 d125. I cannot see any way of draining the oil or refilling it. I recently removed the circular plate towards the back of the transmission case and oil came out. Is there a filler above this which I cannot see or was the oil overfilled at the time the engine was put together?
The only other access to this area that I can see is the square plate at the end of the transmission case. Am I missing something?
Help please!
Thanks in advance.
