Changing the oil in Hypro D-50

Any ideas how i can drain the oil out of my Hypro pump on my sprayer without taking the pump off of my sprayer. The pump doesn't have a drain plug on it. Any help would be appreciated. Thanks.

I just did a D 30 on Friday, seals blew out. If it's like the D 30, the oil drain should be on the side facing away from the engine, in the lower middle of the unit, looks like a brass bolt head.

Thanks for the help, but there is now drain plug on the pump at all. Maybe there are drain plugs on the new pumps, but this one is about 20 years old. I bought the unit used and works great. Just trying to changed the oil without taking the whole pump off. Thanks.

Here is the main body of a D 50, not the complete break down,
number 66 is the drain on the pump, if your pump does not look like this, try here .

My pump looks just like that but doesnt have that drain plug. I must have an old model. Thanks for helping.
