Re: chocolate milk drained
Murky, whitish coloration of hydraulic oil indicates it is contaminated with water. Before you start draining the system, perform the lift test and determine if cylinder is worn too. You probably have more critical issues than just water in the system. The hydraulic system and steering box are the two most neglected systems on these N's. Why? If it ain't broke... Even PM wasn't done on many of these. On the pump, if water got into the system, if it would freeze, then tractor operated without warming up, the aluminum pump base could crack and render it junk. The leak down test will determine if the whole system needs to be pulled. Simply draining and refilling will not solve those issues. The procedure requires pulling the top cover, replacing the cylinder and piston, cleaning chambers, safety valve, and more. Dropping the pump and rebuilding would be recommended as well. Get the Essential Manuals, documents, and video to know how to do it correctly. I use mineral spirits for all my cleaning operations. It works well to clean, thin oil, and flush system without doing any internal damage to parts. Others use a 50/50 mix of UTF and acetone, and some use diesel or kerosene. Pulling the top cover and dropping the pump aren't difficult procedures, just time consuming and involved. You will want to do it right the first time, avoid shortcuts or skipping steps. Having to do it all over if something wasn't right would be frustrating.
