Hmm...I think you may be referring to a steel tubeline that comes up through a hole in your steering lever plate? If so, loosen the jam nut(a large nut surrounding the base of the fitting), then loosen and unscrew the fitting from the pump. If that's what's leaking, there is an o-ring ounder the jam nut.

Its an old 630 the service manual calls it a port block it has 5 lines coming out of it and the temp and pressure switches in the front there is a large nut/plug on top when you remove it there is a slotted screw looking thing with a hole in the middle I have the o-rings and washer for the leak how do I get the screw out?

Oh-I was wayy off there! Did you try a drag-link socket? That's a socket that fits onto a ratchet-Instead of going on to a nut or bolt it tapers to a blade that fits into the slot. I'm not sure if this is your dilemma-I'll look it up and post back tomorrow.

Yuo I tried a hunk of flat stock but just bent it and I dont have any screwdriver that large Ill look for the right tool do you know what size it is? I bet KD tools makes it. that retainer shouldnt be that tight should it? I had a big adjustable wrench on the flat stock and had to really tourqe on it no movement just bending the part leaks pretty good could this give me hystat troubles?

I didn't get a chance to look over that stuff today-sorry, I'll try again tomorrow. I'm going on memory, here. I think that port block serves to divide flow between huydraulic and hydrostatic returns, as well as provide for switching for warning lights, and filter by-pass. Any thing leaking there could give you trouble with the hydrostats. Are you having some trouble other than just a leak?

yup thats what it does according to the book . sometimes the steering gets hard kinda sounds like its low on fluid but it isnt sometimes all good sometimes not so good I just had head gaskets blow the fins were plugged on the heads and cylinders no airflow=too hot=bummer the trouble may have been heat related poor airflow over the cooler but I figured whilst i wait for the gaskets I can fix some other things like this leak Jeff

Hopefully its nothing like Aussie engineering, we just get a bigger hammer.
no not a bigger hammer just an "enlightned" head and a new day. " the difficult is no problem............the impossible just takes a little longer" James Alto ground surgeon. If that guy wasnt using that as his slogan I would Jeff
