68 JD 400 hydraulics acting up.HELP!

[Barry 1]

My 400 uses a AR26375 and there are plenty available on Ebay and amazon etc, Mine was crushed and needed replaced. I see one on amazon for $24, most are around $32

R53169 is a nylon instead of steel version of that AR26375 suction screen but it appears to cost about the same amount as the metal screen.

Ordered one from EBay today. I’ll update when it gets back together and if it fixes the problem.

Is it in good enough shape to put back in? If it's not badly damaged (no holes or crushed) clean it thoroughly and put it back in. The bigger question is what does the sump look like? If it's got a lot of crud in it then it really needs a good cleaning. From my research that has a piston pump. Hopefully it's not trashed it from starving for oil. If it cavitates you can hear it clearly believe me. What does the fluid look like? After the fact and no ever does anything with the fluid until they start having issues and then it may be to late. If it's dark that isn't a good thing. It should be pretty clear and light yellow.

The filter was all collapsed, new one is due tomorrow. The fluid wasn’t dark or burnt but it wasn’t clear. It looks a little cloudy and kind of green- gray. I’m sure there is a little water in there somewhere. I tried to rake out the bottom of the sump as best as possible but it seems like most of the junk was sucked up to the screen . I bought the machine about 3 years ago and the previous owner said that he had it for about 20 years. Not sure if that screen was even cleaned before.
