WHOA IS MY 300U =(

Well you all remember my 300u hydraulics loading up the engine I decided to tear into her today, even tho it is 15 degrees. It's not really that bad when u put 2 pairs of socks and gloves on. Well I decided best thing to do was to take the res cover off and check out the screen. I got the valves off too and am in the process of tearing them apart so I can match up new orings. I got a big surprise under my res cover tho. My filter is smashed. I mean like caved in all around. I figured its cause it was dirty, which it is, and the pump sucked it into itself. So I decided I would clean it off the best I could and use a coat hanger with the end bend 180 so its nice and smooth to reshape it the best I could. Just out of coriousity I looked into the inlet pipe to see if I could even see through the screen. To my amazement i could and instead of the fine screen it was a very corarse mesh screen, I was like WTF? Turned it over and the area right by the inlet pipe's fine mesh is GONE!!

There is definitely dirt in the system. This is bad news in a sense, and good news as well. Bad news because its been like this god knows how long, good news is the hydraulic system still has more balls then I know what do to with. So I guess its off to the dealer to get a new filter and res cover gasket.

I am happy to a degree. It will be nice knowing everything is the best it can be. Also to help flush the pump, I'm going to fill up the inlet hard line and bump the starter over so it shoots out the pressure line several times to get as much crap oput of the pump as I can.

Now, why is the filter crushed? Too much buildup caused the pump to suck it in and eventually to rip some of the fine mesh loose?
This botheres me.
What is all located in the cover? I got the 2 hardline pump orings out, and the oring/filter. Is the rest just passages or are there mechanisms in there I should inspect? I dont wanna take the cover off the lift If I dont have to as it probably weighs 100 lbs.

Im calling the dealer, maybe they have oring kits for the hydra touch vavles which would be easier and probly not much more then matching them up at tsc, doubtful, but doesnt hurt to ask.

Wish me luck guys!! Maybe just maybe this will help my whiney pump. Maybe just maybe the screen recently ruptured when I noticed no more whine, but that was the same time the pump seemed to labor the engine, maybe the 2 go hand and hand, who knows!!

All I can say is the pump should be fine, maybe not the best pressure like a new one, but it had no problems lifting up the front end of a junk car about 8 feet in there air!! Me and my nephew were having a little destructive fun with it!!
