Been searching and searching for a how too on fitting a saxo/106 electric powersteering pump. Anyone have a link or done this themselves, just like a heads up before i start anything.
Cheers Adam
ps:moved house now and the cars finally got a home of its own....A GARAGE! can actually leave it in parts over night, its GREAT. lol the little things in life.
i think antnickuk runs one - best speaking to him about it :D
i was told that the lines are the same fit - so reasonably plug and play
if you do it - take LOTS of pics for a full write up
Well started the electric power steering task today, relatively hassle free so far. As i was doing it i realised that i was doing some things the hard way but hey trial and error and got it out with no complications so pretty pleased
Started by disconnecting the two attached wires which lead to just under the main fuse box.....does anyone know if any effect will come from just leaving these unconnected? The new pump has only a + and - so gonna run one to ground and the other to the ignition with a small fuse in line.

Then removed the drive belt by loosening the small idler pulley locknut and loosing the adjusting nut on top

Once the belt was off i loosend the low pressure pipe (inlet) keep the fluid reservoir cap on though else it\'ll gush out quick

Drain the fluid into a suitable container, all i had to hand was some rag but this was enough as there was not much fluid, to stop it leaking i pushed a small bung in, this did the trick and kept me from getting smothererd

Once i had that under control i undid the two main pressure hoses screwed into the top of the p/s unit, these are the high pressure lines (outlet). One is larger than the other, models with speed sensing ps have only one high pressure line i believe, but models with electronically controlled ps have two.
Once these were removed and pushed out of the way i could concentrate on getting the ps pump out as it was now connected by no hoses or wires. I decided instead of removing the ps pulley earlier and removing the pump from its metal bracket holding the pulleys to just do the lot in one go.
There are five fixings two bolts and three nuts holding the ps bracket to the engine housing next the crank angle sensor. these were surprisingly easy to get at and remove, in the pic you should be able to see the postion of where it was attached

and this is the unit once removed, you can see the five fixing points, two nearer the front of the car and three nearer the bulk head.

Look at the room!!!! The bolts from where you just removed the ps bracket, which will still be sticking out from the engine housing can be unscrewed with a pair of plyers, just to tidy the whole thing up abit

After a bit of a clean up whilst its easy to get too. Also had removed the HT leads earlier to get some more room for my wrench when removing the bracket bolts.

Next i removed the smaller of the high pressure lines by following it round and undoing any bolts, cable ties. I plan to block this one off by screwing a bolt into the pressure line at the base of the strut tower...see pic - the one high pressure line i will reuse as its the same fittment on the saxo\'s ps unit

This is as far as i have got today, heres a picture of the new electric powersteering unit, it weighs in slightly less, not a considerable amount but is certainly alot smaller and you get the benefit of mounting it lower down so you can easily get the FMIC piping installed.

let me know if you need to know anything
Only thing i am worried about is making some kind of bracket for mounting it?
Once i\'ve sized it all up shouldnt be too bad but at the moment i know how i\'m going to connect it up just not sure how to securely fasten it. Hmmmmm
i fitted mine under the passenger side of the front bumper as i wanted it out of the way. Where the headlight washer bottle went
looking forward to updates on this. im interested also.
I had a go at this and i could\'nt master the turning it down whilst moving? It was great at low speed/stopped but a bit too much for me when doing some spirited driving. so i ended up fitting a NA None PS rack (just becouse i like the feel)
i\'m suprised at that as mine is quite firm all the time and was on my FD, Jay took mine out the other day and thought it felt nice compared to his Non pas rack. Maybe because i have a fairly small steering wheel.............
I was thinking about this before, If it makes any diffrence i used a vauxhaull Corsa Pump becouse it had a Bottle on the top and fit well in the Washer Bottle Hole.
I also had a Momo Race steering wheel if that makes any diffrence??
I know on my Fd i am going to keep the stock PS becouse after i did the Mod on my T2 i could not feel any diffrence at all in power or it did\'nt rev any better etc and as i say the steering was a bit vauge whilst Driving hard.
TBH i did it for a reason (IC pipes) but if i was to do it all again i\'d rather get an FD PS casting and lower the assembly rather than getting rid.
But thats just my Opinion, the saxo pump may be a bit less "OTT" but i used a vauhaull one becouse we had one knocking about.
Any more updates on this???
unfortunately my time over the last week or two has been taken up with breaking the EGI, this is however almost a bare shell of its former self so now i turn my attention to the TII again and get this job finished. I have connected up the two P/S lines and positioned the pump where it needs to be. All left to do is make a bracket, which i have the parts waiting, to stop it moving around and wire it in again another simple job, only a pos and neg to sort, will wire it to ignition so pump starts when ignition is switched on.
Whether it\'ll work or not is another question all together lol
Cheers for the interest, will keep updating as i go
Adam
Cool :)
I\'m watching a couple of pumps on ebay at present... looks like a good project and I think i have a good idea where to mount it where it will be really out of the way :P
Yeah mine sat very well where the stock batt sits, as mine is in the pass rear seat bin, this also allowed me to reuse the stock P/S Lines, they also fitted perfectly. Let us know how you get on
Well i was going to bin the stock lines and use some nice new braided ones.
I\'ve not studied the FD PS rack yet... but in your pics above you were talking about blocking off one of the lines? Did you need to do that in the end?
From looking at the Saxo pump it has two lines and the res.
Will see how i go on... :)
Yeah there is two high pressure lines going into the steering rack, on the stock pump there are two High Pressure outlets, on the saxo pump there is just one, the larger of the two. This is why i\'m blocking of the smaller, dont think it does anything to important and shouldnt cause any concern. It could be blocked off at the actual base of the rack, this i may even do yet. The other line on the saxo pump is the low pressure inlet and yeah then it has the res.
Perhaps it\'s speed sensitive steering or something like that... I\'ll consult the manual and probably come out non the wiser :P
So i assume the second connection on the Saxo pump is a return?
I guess you\'ve retained the stock RX7 S shaped "Power Steering Cooler" - I was thinking of ditching this and running a small PS cooler... what do you think :)
Cheers for the advice
Yeah the second on the saxo pump is the return, the low pressure return line. I have retiained the stock p/s cooler (s shaped) literally took the stock pump out and stuck in the saxo one with the same connectors, just blocking off that smaller outlet hose.
I havnt thought to much about an aftermarket p/s cooler, i think the stock one works well and is ideally located, its also nicely plumbed in and seems an extra \'To Do\' job that i could do without. Would be a nice little upgrade though
whats the pro`s n con`s for this bud? does it make much more room removin the standard one?
Pro\'s for me were that i could fit the piping for my FMIC, this is why i did the mod. Once removed there is alot more room, even more if you have the A/C out too. Not much difference in weight, maybe the stock setup coming in a little more but not much. Should also help take the strain of the Eccentric shaft pulley. I have only the Alt and water pump running from this now.
Any idea what the pressure and flow rates for the pump are?
