I have an older b7100 with a b219 loader, i just rebuilt a cylinder ( just as i have before) . It worked fine at first, then after a bit it's actions got choppy and slow. I'm wondering if i got a piece of debris in there putting the lines back on. Does anybody know if there is a screen in that hyd system, and if so, where. Tyia

There is a screen. In the pic below, the hose clamps to a 90 degree fitting that is screwed into a large hex nut. The large hex nut is actually the filter screen. Only problem is that when you unscrew it, you dump all the hydraulic fluid. There is a little sump below the screen that usually has a lot of sludge & debris in it. Pain to clean, but worth it.
