HiYa Matt-
Welcome aboard the NTC! The best group of Ford Tractor guys in the world! Here is a LINK (see below) to an article on hydraulic repair but it is for the 8N system. The NAA/Jubilee systems were a bit different but use the same cylinder and piston. The NAA pump is a servo-controlled, balanced van type, driven off the engine camshaft gear. If the oil is clear and honey-like, and not muddy, milky-brown, or whitish, and you didn't change it, then perhaps the guy you bought it from just replaced the oil prior to selling it. As mentioned, perform a simple test via the inspection covers. Attach a load, raise it up and leave it, then shut down engine. Look up into housing at the cylinder and observe if oil is leaking down from it. If so, your cylinder is worn and needs replacing along with the piston, O-RING, and leather back-up washer/wiper. A new safety relief valve is also needed but if the pump has not been cleaned, it may need to be pulled, inspected, with chambers and valves cleaned and or replaced so be prepared to do some work. The job is not difficult, just time consuming. It is best and highly recommended that you get a buddy to help do the job. Lifting the top cover should be done with two people. Many of us also recommend too you invest the essential owner manuals to help understand and do repairs better. Get a copy of the OEM NAA Operator's Manual; a copy of the I&T F-19 manuals, and a copy of the '39-'53 MPC (Master Parts Catalogue) -all with detailed specifics on all the systems. We have an older version of the F-19 Manual in our MANUALS library, but the newer editions have much more detailed content. ALL of these manuals can be found at JUST8Ns.com as new repops. Keep us appraised of your progress.
