Many thanks, Paul. I guess I had some bad information about them being closed. This helps out a lot.

Good to know about Northern Tool. Thanks again.

Okay, after further research of this splitter, I've pretty much determined that this unit was originally a Northstar (Northern) product. It has a 2500 psi Prince tie rod cylinder and control valve. The pump is a Haldex Barnes (# 1057) which has a Northern nameplate attached to it.
As I've said previously, the oil reservoir has no drain plug on it. After inspecting the low pressure hoses (1-1/4"), I've purchased both pieces that run from the tank to the pump and also from the valve to the filter, but I haven't installed them yet.
What is the best way to get as much old fluid out of the entire unit before installing new hydraulic fluid? Thanks in advance

There is no drain plug on the bottom of the tank - only the filler neck on top (see previous pic) and the outlet on the side where, I'm assuming, a strainer will be that I can remove. It has a vented filler cap (pic) and no dipstick.
If push comes to shove, I could remove the tank, fill it with a half gallon of diesel, shake it, and pour it out.

I've also gone the route with Northern about a whole unit number, but to no avail.
