JD300B hose from Hydraulic filter to Transmission Help?

[Tx Jim]

Get a 5000# gauge with a short hose. Connect hose to orifice where plug(key 24) is located on RH side of hyd pump. Connector size required is 0.375 IN/24 TPI/ORB

Okay I will buy and test it out.

Right now what was wrong was the hydraulic fluid was really milky and had a hole in a line squirting fluid. I changed the hose. Now changed out the milky fluid, transmission filter & hydraulic filter.

When I move either of the Backhoe levers somewhere below has a loud continues vibration Thud like sound.

Did you check/clean hyd oil sump screen?

I got it pulled out just a little and it looked clean. I could not get the whole thing out because it was stuck and would only spin but would not pull out.

Screen should pull out of trans case if not clogged or crumpled.

Yea it only came out maybe half an inch? Then was stuck in there and I didn't want to rip it out and break a piece off inside so I just slid it back in and put the fluid in. The fluid was so milky and the filters was so tore up I figured that alone may do the trick.
