Searched through the old threads about this and a lot of speculation was there, but no results. Has anyone upgraded the Range Rover style PS pump to a Saginaw unit? For a RRC you cannot have the Canned Ham style pump with the integrated reservoir as the PS pump is mounted underneath the alternator. I am upgrading some of the hoses and adding a PS cooler and thought I might consider upgrading the pump while I'm in there.

If there is nothing easily available (Not sure I want to really undertake this one yet...) I will probably just mod the existing pump with KC's instructions and see what that does for me.

edit: Can anyone verify that the '95 RRC pump is indeed a sag pump? There was some speculation of this a while back.

One more thing, for my '90 RRC I don't have a serp belt, I have the dual pulley on my pump.

Why not try to mod your pump first and see how it works for you. It literally took 30-40 minutes to do the job. I *think* I used a 5/32 bit and it helped a bunch. You might want to try a smaller bit at first if you still street drive cause mine is SENSATIVE; that may be due to the hydro assist and the increased flow. In the lower RPM range it is still a bear but when you get bound up just step on the brake and get the RPMs up a bit and it works like butter.

This is the direction I am leaning. My pump is about 4 years old and hopefully still has a lot of life left in it. I am definitely having better hoses made that hopefully handle the increased pressure.

Larry, what are you doing for hoses? I visited this a while back and the local Hydro shop said not much can be done with the plastic LR resevoir. I was thinking along the lines of HD fittings of some sort but basically they said, "With that plastic crap there their ain't much you can do other put a hose clamp on it..." I would be curious to hear what your working up. Did you use a different res?

You dont need to upgrade the res hoses, cause they are low pressure.

Wasn't planning on upgrading it due to leakage, just thinking about replacing the plastic reservoir with a metal one that has an actual fitting on it. I thinking more long term and durability more than anything with that. Ultimately I will go with Ram assist and I might as well upgrade everything accordingly.

Ryan, I am thinking about making a much shorter high pressure hose out of braided hose. Probably take mine down to the local race shop and see what we can dig up. I'm also going to have 2 braided hoses made up for the tranny cooler lines as well. Probably keep the stock hard lines that run to the bottom/front of the radiator and cut them there. Then flair and fit some more standard fittings that will continue to the Tru-Cool Tranny cooler I picked up. I'll try and take some pics as I go along.

It's a ZF.

Saginaw makes several different configurations, some of which have the remote reservoir.

As for hoses, they're no big deal. Lop off the metric bump fittings (or flared if working with non-serp), braze/silver solder more common fittings in place, go to tractor store and buy mating hoses.

There are many alternatives for the reservoir.

Larry,
if you do want to get away from the Rover pump you can try a Pump from a 83-9? GMC 6.2/6.5 diesel. Its the same pump as the GM canned ham pump, but it has a remote resevoir. It does have two return line fittings in the pump, but it is easy enough to cap one off.
For the Hi Pressure hose its simple to make up hases using Earls fittings and hose, all available from Summit. It might help to save some $$. Specially since you are doing tranny and PS. You want #6 hose and fittings. And then 6-to-? fittings.

Pete:
Are these hoses capable of withstanding ~1500 psi?

I have the part numbers for bump to AN fittings at home. You might try a search on the general forum-that's where I found the reference :flipoff2:

After just visiting the speed shop I suspect the answer to this question is no. Not sure what a good alternative is. I think the tractor supply might be the best option. I also want to shorten the high pressure hose from it's factory 80 feet to something a little more practical, maybe 12 inches.

The basic hose is 1500psi. But they do make PS hoses rated at 2500psi.
Same goes for the fittings.
A 6' section of Aeroquip's TFE racing hose is 34$.
A 6' section of Summit(1500psi), for the tranny, would be 24$
6AN fittings for the TFE are 6.40ea
Regualr 6ANs are 4
Adapters are 2-10$ depending on the use. My Hydroboost uses o-ring fittings and were on the hi end. Pipe thread adapters are on the cheep end. I used all the same hose for the three pressure lines, 2 return lines, and lines to the cooler. Also add in 10' of 8AN hose and fittings for my oil cooler line and some 4AN hose and fittings for the clutch line. I spent between 150-200 for all of the hoses and fittings. I still have a couple feet of 6 hose to use for my fuel lines.

Are the values you found for the saginaw pump or the Rover pump?
All of the saginaw fittings got listed in a billavista thread...by me :)

3' is the shortest I have seen. 19$
I use a dremal but a hack saw blade works great.
So 32$ and you will have the base hose, minus adapters.
Depending on the size you need, there are some other ends besides just 6an available. Might save a few more $. :D

This sounds familiar. Just today I was getting all the materials to do this for the Transmission Cooler.

My hoses all use JIC fittings. Very ccommon in industry, but not as common as John Deere whicch is the direction I'm going.
With respect to the power steering hoses, the length is kinda critical as space is limited and the hoses aren't as flexible as one would expect/hope.

Braided stainless looks cool, but in my experience, is every bit as frail as the stock. The NAPA shop-made hose I now have seems to be more robust, but I carry a stainless as a trail spare.

I've found some tranny fluid pressures. If the Rovacom is to be trusted, tranny pressures can run as high as 325 PSI.
