Figured it was about time for a new post about this. I'll copy and paste the important stuff from the other thread. Today I took the parts out of my new pump, modded them, and stuck them into the pump on the truck. HUUUGE difference. It works exactly how I hoped it would work. Lock to lock with my pinky, on pavement, at about 900rpm, 6psi in the 42's. Too cool! Pictures- Remove the big fitting from the back of the pump, takes a 1" wrench- Fitting- From right to left, these are the parts inside the pump. 1" fitting on the right- First thing I did was drill out the hole in the large fitting to 5/32"- Next I took the flow piston apart. Requires a 7/16" wrench/socket. These are the parts inside the flow piston. I removed the shim, second from the right, and just barely took a bit off the the small end of the limiting stud (4th from the right) with a file. Re-assemble- Then I stretched out the large spring from inside the pump housing till it was at about 2 1/2"- Just doin those few small mods made all the difference. Before, at anything less than 2k rpms, I had nothing. Now it's lock to lock standing still with my pinky. I got most of the info from the West Texas Off-Road website- http://westtexasoffroad.homestead.com/powersteering.html One other thing I might try, thats not listed on the WTO site, is this mod to the main fitting- Supposed to help flow from idle to low RPM's. That info I found in BOWTIE's photo gallery- http://www.texasoffroad.net/galleries/members/albun67?page=1 Might help bring the assist down to idle rather than the 900rpm's it seems to really kick in at now. All in all I think I had about two hours from start finish on the pump mods. Hardest part was getting the fitting off the pump in the truck- draglink and engine x-member made it hard to get wrenchs in there. Otherwise it's a pretty simple project.
