Getting final tweaks done to be operational. First the manual, nor the small info pack on the hydraulic motors tells you what size the fittings for the hydraulic lines are. I pulled a motor off and took it with me to the hose place so they could make sure the fittings were correct. Additionally, for newbs and non tractor people, the remotes on the back of tractors are typically a Parker 9006-001 yy (sometimes Pioneer, made by parker by the way.) If you have these, the male end for your hoses will be an 8010 series connector. The ball versions have no alpha character, 8010-4. The poppet version has a P in the part number like 8010-4P. The break under pressure version of the poppet connection has the "DC" suffix 8010-4P-DC. The difference in the number in the middle is the threaded end size: 8010-4 is 1/2 NPTF 8010-15 is 3/4. If you look at the fitting for the break under pressures there a little hole in the poppet in the bottom. Any of the 8010s will fit these 9006-001s; poppet or ball. However it makes no sense to pay the extra couple of bucks for the break under pressures if your tractor side is ball or regular poppet.
So more learning.
