I had to buy part 170, the one i got with the case was different or custom. I also had to buy the pieces inside the case because mine didnt match exactly. Instead of the hydraulics going from the pump to the case, i ended up going to the bucket valve first, then the hoe, then the case because this case doesnt have the same inlets. It was a lot of experimenting, trial and error to get things to work, not to mention the money.
