Hi,i converted my car some years back.I used a lhd rack turned upside down it had to be shortened and the mountings altered .I used an electo/hydraulic pump from an astra cica 2003 reg and mounted the pump into the n/s/f end of the bumper.The pipes were therefore short and the wiring could go straight to the battery keeping the car looking as standard/unmodified as possible.Mobile 07811115791eve if more info is requierd regards john

Hi,
Hope to help if I can.
The belt driven pump will require a bespoke bracket, which mounts both the alternator and the pump, not rocket science stuff, but I have not seen a spare one for some years. Making one is probably the option. the reservior is a remote unit, standard off the shelf ZF part, VW LT van if I recall correctly. The pump itself is a ZF unit, however the flow rate needs to be modified, to reflect the potential engine speed. I can get the part number of a pump for you, if that would help. The pipe runs themslves are easy enough, but will require the gearbox out to install them neatly, along the top of the tunnel.
The electric pump option removes lots of the dramas, however locating one in the front can be a pain, I have seen a couple of real foul jobs done in the past.
Whatever you choose to do, make sure you use a suitably pressure rated hose on the feed side, there can be significant peaks on full lock for example. Dont be temted by cheap fittings either, they are just that.
Shortening the rack is rather specialist work. The casing needs to be shortened and a new rack bar made. getting the length if this right is vital to preventing bump steer.
Cheers
Simon

Great i think i have a good idea of whats involved now, in two minds which way to go.
Got a quote from Julien Godfrey now for the full conversion which is reasonable, but i like to work on my own cars, mainly because i enjoy it and it also gives me a better understanding of how everything is put together on these cars.
I may ask Julien to just supply a modified rack and take care of the install myself, which sounds straight forward.
Simon (blue oval boy) would be useful if you can provide some part numbers for the ZF pump and resevoir
Cheers to all that have provided their advice so far, if anyone has anything new to add that can help with the mod feel free to post.

This is the mounting bracket you would require, as Simon says High pressure line is better with a swaged hydraulic type hose, like what a JCB would use on hydraulic ramscxa2000 wrote:Great i think i have a good idea of whats involved now, in two minds which way to go.

Torqueatif, thats a hell of a mounting bracket, cant quite work out how it would fit looking at those photos, but i assume it all becomes clear when i come to do the work
Is that a spare bracket you have available, or do you know where i can get one

I got it with spares I purchased, it is the works type and written on it was "LAST BRACKET PATERN ONLY"cxa2000 wrote:Torqueatif, thats a hell of a mounting bracket, cant quite work out how it would fit looking at those photos, but i assume it all becomes clear when i come to do the work

It is not for sale as it is for my car. As Simon says they are very rare, I think you would have to get one fabricated.
The Pump I discovered is from Audi 4000, all models to 84-87 including quattro (zf 7671955140)
What would be helpfull is if anyone has a spare bracket i could borrow as a pattern for a fabricator, can anyone help with this.
I assume the ZF pump you mention (torqueatif) is the one that the bracket is made for, so once the bracket is on its a simple case of simply bolting the alternator and pump to it.

Yes, I assume the same thing as I have not done it yet, Simon will know for sure has he has fitted them.cxa2000 wrote:What would be helpfull is if anyone has a spare bracket i could borrow as a pattern for a fabricator, can anyone help with this.

Depending on your engine revs you may need a different size pulley, the Audi probably revved no more than 6000-7000 rpm. if you have a 10,000rpm BDT obviously it will over speed the pump. Maybe Simon could fill us in here as to whether the pump needs a different spring rating or is okay with just pulley changes?
You can borrow my bracket If you Promise to look after her and keep her warm and well fed!
Torqueatif, the bracket could'nt be in better hands i will even read it a bed time story every night and give it a cup of cocoa, i will drop you a pm.
Simon (blue oval boy) any chance you could confirm that the bracket that torqueatif has is suitable for my standard 1800bdt engine and any mods required to the pump as per torqueatif's previous post.

Hi Guys,
Torquative's bracket looks right from the photos, I will give him a call and talk it through.
I remember there being a number of variants tried, as you say it is a bit of a beast. It's worth considering the loads involved, the weight of the pump and alternator bouncing about and vibrating, shock lodas from the pump and so on.
The pump needs both pulley and spring mods, one influences flow, the other pressure. I may have a pulley, they are not hard to make either.
If you want to talk it through, give me a call, 07521 803489.
Cheers
