In Reply to: 8N oil pan removal posted by Jim Menke on January 07, 2023 at 17:35:38:
Was the pressure loss all of a sudden while running or was it noticed after the tractor had been sitting for a while? I assume you'll drain the oil and reach up into the drain hole to verify that the pickup tube isn't intact. Lots of things can cause a loss of pressure. One of my 8Ns sometimes loses pressure if I let it sit for weeks without running. This is especially true in cold-weather months. It's an easy fix by removing the 13/16 nut near the water pump and shooting in a few squirts of heavy oil. I may have worn oil-pump gears, but it's not bad enough to justify tearing things apart to fix. (My normal oil pressure is 35 pounds on startup and 25 pounds when warm.) You may have other problems than the pickup tube and screen; I'd hate to see you pulling off that heavy pan without checking other things that may be easier to fix. (Gauge, lines, etc.) Good luck with it.
