I have had a crash course in tractor hydraulics 101. I completly tore these down to the bare essentials. I found that moisture can and will get into the detent assembly. I glass bead blasted all small parts and used Teflon assembly grease liberaly on this upon re-assembly. Sorry, no before pictures, but trust me, it was funky.Re-assembly went together well after stoning the sides of the housing and deep cleaning in a bucket of diesel. All new o-rings and $75.00 worth of CNH parts to restore the detent assemblies (CR-steel balls, springs, unlatching pistons, ect). I decided to trash the banjo fittings and use ORB to JIC. I hope this is an upgrade. Has anyone done this conversion before? Enjoy the pictures. Also, I have found the TC-88 parts manual to be invaluable!
I have two more valves and an end plate that I may recondition and list on EBAY. I can notify ya'll if interested when I list them. Contrary to the pictures, I cleaned the "work environment" before assembly and wore latex gloves. Can never be too clean with hydraulics! Thanks for all the help with this 1962, 504 D so far. Charles
