Halfway through a switch to the heavier steering option on a 1700. (Wow does it ever help having a pit and an overhead crane!) Can't put my hands on part numbers with a decent drawing as the plumbing is slightly different between LS3 and LS7. I have had the parts kicking around for a while so they don't look familiar and am wondering if anyone has a decent picture with associated part numbers. I have the maintenance book pic but of course no part #'s. I am hoping to use original reservoir. Lower steering shaft boot looks to have a different engagement to the top of the steering box. The LS3 had a nylon disc that fit over the splines and the boot wrapped around this. Anyone out there worked this switch that can illuminate me on the fiddly bits? Thanks

Here is diagram; I am looking for part numbers for all the pipes/hose/tubes/banjoes etc. that run from reservoir to pump to box. Thanks in advance for any info.

Curious, what is the difference in these options. I really didn't know they existed.

Ones Heavy Duty? jk, no idea, but here's the LS-7-F from a U1700 (435-110), is that what your looking for?

Thanks Trev; do you have the corresponding drawing that shows what goes where? (similar to that pic I posted of the piping)
The 'Heavy Duty'...LS7 develops more steering effort (if that is the right term) according to the specs in the maintenance book. I always seem to have a lot of weight on the front end so I think this should be what the doctor ordered. It is quite a bit bigger in the steering box portion. The pump looks almost identical in size at first glance. I haven't taken the old pump off to compare but they are not much bigger than a fist. The pics I have taken so far are too sh**ty to post...I'll see if I can make a better job of that for those that are curious.

No, I have all the sectional views ect from the repair manual but no overall hookup diagram.

apparently there was an LS3, LS6, and LS7

There's a LOT of documentation, some talk of flow limiting valves ect ect...

LS7 requires different pitman arm ( splines are larger)

Does anyone have one of these larger spline pitman arms around?
I believe the part# to be A4254630501

I am tying up a shop bay so time is definitely an issue.
Thanks
