My oil pressure is about 5 lbs at 180 to 190 degrees.Seams a little low.Can I roll in a set of mains from the bottom without engine dissasembly? Thanks in advance;

What tractor? Thats probably about right for a WD. You can also add or remove (I forget which) a shim on the oil pressure regulator. Oil pressure on a W engine is controlled more by cam bearings than mains. I'm sure you could roll in new mains, though.

On these, you don't "just roll in new bearings"..
You must adjust the shims on each one..

Oil pressure can be affected a great deal on these by the Back-Pressure (restriction) to flow in the standing tube, in the oil filter..
Are you sure it is in there..??
Few gauges will read accurately at such a low pressure..even AC gauges vary..
Put one on from an AC that shows proper oil pressure, to check your gauge..
