Picked this up last Friday. Everything works, but the chuck is stuck on the spindle. After an hour I got the nut loose, but no go on the chuck. I would assume the idea is to use the nut to push the chuck off. I went this route, but no luck. Any suggestions? I thought about heating the chuck thread area up to help release it from the taper, but I haven't yet.

I also would like to get the coolant pump running, is this worth it or should I go with some.sort of replacement?

I'm also in the market for a steady rest if anyone has one laying around. I've attached a few pictures of the machine.

Tear down your coolant pump and rebuild it with fresh seals and bearings. Everything is rebuildable on these machines, and usually with nice common parts you can source from any supply house.

Hopefully that L0 won't give you too much trouble. The key probably rusted inside. Remember, if you gotta reef on the chuck, put a piece of wood down on the bed to protect your ways.
 
You loosen the nut and rotate it CW looking at it towards the headstock, put the wrench on it and whack it in CW rotation with a hammer on the wrench, and the chuck should pop off the taper.
 
If the ring is loose, get a long pipe, bigger is better so no bend, grip it in chuck then wiggle the end, it should come loose.

Leave the ring on one turn to keep chuck from falling off.

If you get lucky the coolant pump might not need anything more than a good cleaning. I've had a Startrite saw that's coolant capable for over 20 years. The saw was built in the 1980's and spent the first 20 years of its life in a production shop. When it became obvious the saw was undersize for the jobs at hand the owner sold it to me rather than run it into the ground.

I've never used the coolant system because I hate the mess and the smell of rancid coolant. Late last year I had to replace a seal on the gearbox so I thought I'd take a look at the pump. The only problem turned out to be dried coolant seizing the impeller to the bottom of the reservoir. A good cleaning with soapy water resolved the problem. I've tried it a few times with water only and the system works great. I still haven't filled the reservoir with coolant because the saw has been working fine in the dry mode.
 
Victory. 3 days of Kroil oil, tightening the nut as tight as I could get it, and a bit of heat did the job. Spindle has basically no run out.

Nice score on the lathe! I love the travel dial! I'm glad you got the chuck free.
