Power steering not working

David Wayne · Mar 30, 2011

I posted this under construction, no replies so i will try here.

I have a ford 4500 TLB that I have been fixing up for the last couple of months. I have pretty much rebuilt the front end to reduce steering slop. Now the power steering doesnt work.
I dont suspect the pump as it worked before, oil level is OK. It shares the oil resivore with the backhoe. Pins & bushings are not too tight, I can turn it by pulling on the tire while it is jacked up. I did go the cheap route when replacing the hyd. fluid & bought 303 that is on sale at TSC & it is a bit thicker oil?? And I dont know what the little linkage is on the PS cyl that controls a valve, or how to adjust it. Any help will be much appreciated.
Photos will be along later I am not good on the computer, thats what I had kid for. And sorry for the spelling, cant find spell check. Got to go to work now. Thanks again.

Today I adjusted the linkage on the cyl. with the wheels off the ground. I cant go either way without the wheels turning so I guess its set right. Also tells me the pump is working, 1st adjustment was with the tractor not running,turnned it way too far. when I started her up she was turning quick & I couldnt stop the steering wheel,had to shut it down.

i veey much doubt it was a lube issue.. probably could put atf int here and it would work.. though not the ideal fluid.

start checking for flow and pressure..

post back.

Got busy working on other things, now i am back to the tractor. I decided to take it all apart again since the PS cyl leaked some. With the parts on the bench I was figuring out how this works & I think I screwed up. While re-rounding holes & adding bushings to take out slop,I took out the play needed for the rod to operate the valve on the cyl. So all I need to do is remove my bushing. I will know in a few days for sure when I put it back together.
I will post how it went (with pics.) when I get done
