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
With a little yankee engineering I got that blasted thing off now just some o rings and good as new thanks for the advise
Hmmm....Yankee Engineering? =)
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
