Has anyone added a 4 port aux rear hyd valve kit on a 2638HST? I just received the kit for my tractor and it cam with no installations. For the most part it is self explanatory except it came with a filter screen and spring and I have no idea where it goes. Fairly certain it goes in one of the oil ports but not certain which one. I contacted my dealer and they have no idea and said they would contact Mahindra but no idea when they would get back to them. I'd like to get it installed ASAP.
