GM Power Steering Pump conversion

[pmatusov]

Typically Land Rover steering reservoirs have a screen in the reservoir that will cause cavitation in the pump due to inadequate flow. For example, my brother in law's DII steering pump came apart (only catastrophic failure I've seen) and when I put the new pump I couldn't get it to bleed. Turns out the screen was clogged with metal from the pump. Whenever I do a steering repair I always flush the system before repairing and then replace the reservoir.

This one definitely does have the screen, I will check.
FWIW, the catastrophic failure of the pump I had in the white D1 somehow allowed the metal pieces to go through that screen (which likely destroyed the junkyard LR pump I found in St.George in about 500 miles).

Well I would think that when the pump grenaded it sent metal into the steering gear and cooler before making its way back to the reservoir. I'm assuming you didn't flush those out before replacing the pump since there was a catastrophic failure.

LOL, no - I was already stretching my welcome at the junkyard, working on my truck. The Saginaw pump went in with the filter in the return line.

Glad you are happy with it and all but these are definitely what could be called extenuating circumstances.

With regards to the pump application, that "same" ZF pump is used on just about every vehicle that doesnt use the Saginaw pump. Jeeps, newer Rovers, you name it. Calling it undersized is a bit of a stretch.

Same with the ZF4HP22 - trans failure is pretty uncommon with those in general, the issues they do have are design related not strength or size related.

Seems like you are just one of those haters, which is fine

This is my last response before I resort to name calling.
I am not a purist by any means. I love my trucks, and I will not hesitate to use [what I consider] a better part or technical solution if it allows me to keep them on the road longer. This is why my 68 Wagoneer runs on 24-spline D1/RRC axles, and this is why I will eventually rid my mid-90s Land Rovers of [what I consider] fundamentally flawed steering setup. Next step for me - find a way to use Saginaw 76-series steering box in the Land Rovers.

Say no more. I personally just find that ZF stuff is generally good and works. We're allowed to have different opinions aren't we?

With regards to the Saginaw box, its been done. I used to have a blueprint for a new panhard bar bracket that allows the Saginaw box to go on the outside of the frame.

For more inspiration look at the P38 steering box/panhard bar bracket.

No reason for name calling...

I like the idea of the steering box being mounted to the outside frame rail.
Saw a write up of the P38 box in a Series IIA and somewhere have pictures of a P38 install on a ROW 90.

Sent a request to Nick to buy the V8 GM steering conversion kit, but no joy as of yet.

That makes me think of the 60 series Land Cruise in my neighborhood that has a Rover V8.

That totally makes sense for me.
With the Jeep, I should've used Dana 44s from 73-79 Wagoneer, but little jeep people stole them all. So Rover axles were an upgrade from a two-piece rear 44 and a close-knuckle Dana 27 in front.

I mean, if I were to for some reason buy a LC, that would be the one for me!

Sorry for dredging up an old thread here but it's relevant to my current project. I've got a gm engine with the Saginaw style pump that I'm planning to connect to a d1 power steering box. A friend cautioned that the gm pump might put out too much pressure for the box and it might be a better idea to look into using the Rover pump instead. Just wanted to get a read on how things have worked out in the long term for people running this pump with the Rover box.

My brother custom fit a 1600psi pump in his disco 1 and it has been working great with no problems for years

So far so good, for about 25 thousand miles.

Thanks, though it looks like due to space issues it may be that I have to go the other way and mount the Rover pump on my gm engine
