I had an industrial model Ford 4000, but it had a huge cast iron nose and grill. The tractor you are showing is not the industrial model, but it might be a regular 4000. Sorry I can't help much because I gave away all my reference manuals when I sold the tractor. Mine was blue and yellow.
Also, the hydraulic reservoir was up under the cast iron nose, and the pump was on the front of the crank as you describe. The nose ended just before the hood lift-up hatch. Somewhere I have a picture of the "beast" I'll try to find this weekend and send you a scan.
