Power steering.

ok - its time to bite the bullet and get it done - not least becuase my steering is soooo loose it was an mot failiure at one gge and i had to get it motd again with a sympathetic tester for a pass :)
Its a 3500s with the normal box and id like to convert it to PAS. is there an online guide for this? i note the threads below which seem to involve using a corsa component of some sort but TBH i dont really understand how that would work and also id like to hang onto some originality.
can anyone help? i seem to remember finding such a thing before - i remember there being some wierd complication inc moving the wiper motor but cant find it now!
ive got a SD1 PAS pump sitting around from a previous project, is this any use?
 
Hi Paolow.

The best thing you can do is get a complete PAS set up from a p6v8,including the wiper motor set up.And then its only a matter of bolting it all in!!
It can all be done with the engine left in,but it can be a fiddly job.
If you are a capable mechanic,and your car is not a daily driver,then I reckon you could easily do the transplant over a weekend!

Hi guys, great forum - somehow I haven't come across the site before.

Anyway, I was looking for a little info on converting a P6B auto to PAS and here's where I found myself.

I currently have a reservoir, pump and PAS steering box sitting aside. They came out of a wrecked low-mileage (10,000 or so!) P6 and after having them cluttering up my garage for more than 10 years I'm finally keen to put them in my 3500.

What do I need to know? What's this about the wiper motor? I notice that my standard front pulley has a second groove in it. Can this be used to run the pump? What belt do I need? Etc, etc?

Best regards,
Warren
 
Hi Warren.
Are they all still connected with the pipe work,and mounting brackets?
The lower pulley 2nd groove is for the PAS belt,just buy a std P6V8 PAS drive belt!
I remember somewhere saying that the wipermotor set up is different for the PAS due to the positioning of various items!!
My car has PAS as std,and the V8 I broke for spares to get the complete PAS system as a spare had a different wiper set up to the non PAS cars!
Sure somewone will say if I am wrong!
If you have all the parts,its just a matter of fitting it all on in the right place!
The most difficult bit is the steering box!!
Easier to do it while the engine is out if you are restoring it!! :wink:
Good luck!!

Hi Dave,

I have the pump, reservoir, and steering box. There is also a large mounting bracket and the reservoir has two large rubber hoses attached to it. It's pouring with rain at the moment but if there's a break in the weather I'll nip out to the garage and lay everything out for a photo and you guys can see what's what.

Years ago a friend of mine owned a 2000 which he was converting to a V8 (he wasn't really a purist, this guy). The donor car was a low-mileage example that had been written off in a crash in about '79 when it had only 10,000 miles or so on the clock. I remember Jon starting the conversion in about 1991 and then giving up towards the turn of the decade, at which point I obtained the PAS parts from him. So as far as I know they are low-mileage parts but have been sitting unused for 30 years. I intend to get them cleaned up and overhauled before installation of course.

My own P6 is a lovely original 1972 example in extremely good condition that I've owned since the mid-90s. It is not in need of restoration so the conversion will be done with the engine in situ. I recently quit my job (workplace stress was rocketing skyward; workplace morale was going down the toilet) and suddenly being without a company car after 10 years I decided my best option was to get the Rover roadworthy again after 7 years of mostly sitting around in storage. So far I've had to overhaul the brakes and the carburettors but the rest has been plain sailing and the old girl is getting close to a WOF (NZ-ese for MOT). After resurrection I'm planning to get a few cosmetic details attended to (some chips and dings taken out of my 10 year old bare metal respray job; a small crack in the dash; etc) and then it will be some regular use at last. Lovely car, can't contemplate replacing it with a modern.

Thanks for getting back to me.
 
Here's a photo of the car itself, taken during a rare jaunt outside the garage about 4 years ago.

Hi Warren, thats a familair P6 :wink: It will be good to see your Rover getting some road time again. This site certainly has some good hints and tips, I only recently stumbled across it, I dont know if Ben is on it but I am sure you will inform him.

Well of all the people! Hi Graeme - it's a small world isn't it? I only came across the site this morning while Googling. It's nice to get some prompt answers back too. We'll have to catch up some time. I don't think Ben knows the site but then he's not paying much attention to his P6 at the moment. It's currently stored in a container belonging to me and my father...
 
I too found it whilst looking for some aftermarket parts for mine particularly a new Mallory distributer, but it has rekindled interest in some other mods such as upgrading the sway bar etc.

Hello Warren,

The track rod and the mounting bracket for the steering idler are also specific to each steering system. What the actual differences are I cannot say, but I am sure that someone will let us all know.

Ron.
 
Hmmm, that might complicate things a little. I've just emailed JR Wadhams to see if they can shed some light and if they have the required parts.

Cheers,
Warren
 
Hi all.
IMHO!!
The best person to speak to,get the best advice from is Ianp6man!
If any of you guys need help locating hard to find stuff for your cars at our british autojumbles,give me a call!
If its a small item,I can send it to my mum in Waipu, Northland, with my regular mail shots,and get her to send it on to you!
Be aware that anything over 2 kilo costs a heck of a lot to send overseas these days!!
Nice looking motor!!
And yes I think the steering rods are slightly different!
The bast thing you can do is as you say,lay it out,and take a pic,then compare carefully whats on your car now,to what you PAS bits you have!!!

First the wipers. Non PAS cars have a system with a series of pressed steel rods and crank levers to operate the wiper spindles mounted to the drivers side of the car. This gets in the way of the much larger power steering box and was therefore replaced on PAS cars with a more conventional worm drive system mounted on the passengers side of the car. So a wiper transplant is an essential to undertake a PAS conversion.

As far as I am aware the only variation to steering idler boxes was on the 2200TC which used a cable throttle as far as the idler box where it converted into a rod sytem for the rest of the journey to the carbs. 2200TC's therefore have a special idler box mounting casting carrying an extra cast in bracket for the transition. All other idler box arrangements are identical. (this cable throttle system is generally reckoned to be significantly superior to the rod arrangement and is a worth while conversion in its own right) There is a good chance you will benefit from a refurbished idler box and these are available as recons from several sources in the UK and also in Australia - if you need any more guidance ask! The idler box contians a damper to deaden the steering somewhat and I believe there may have been some variation in how stiff these were set, but there is no practical reason why any particular version should be used with PAS. In parctice most dampers will in any case be ineffective at this stage in their lives! - and this will improve steering feel!

There is one variation in the steering linkages. Very early 2000's have a fixed rod between the steering boxes and adjustable side rods from the steering boxes to the uprights. Later cars and all PAS cars have an adjustable rod between the steering boxes and fixed rods to the uprights. Since the output crank on the PAS box is in the same physical location as the equivalent on the manual box I see no reason why an early set up shouldn't be used with a PAS box. But I wouldn't have thought there were any V8's built with this set up.

Apart from the wipers the conversion is extremely straightforward.

Hello Warren,

As your lovely P6B was fitted with manual steering, does your crankshaft pully include the additional one necessary for installation of the power steering belt?

Ron.
 
Re: wipers, only the series one cars have the link type setup fitted to the steering box, all series 2 cars have the rack type fitted to the passenger side (RHD). As no series 1 cars had PAS as standard it was never a problem. 4 cyl cars had the wiper mounted on the steering box until the later type steering box was fitted, (series 2) then they went over to the rack type.

The track rod for PAS has a long and short TRE with an adjuster on one end (drivers RHD) all the others have a normal rod with a TRE at each end.

The additional pulley to drive the PAS pump just bolts to the back of the non-PAS one.
 
Gents, thankyou very much for all the info so far.

The following is a picture of GF148 parked in the garage with the PAS components I'm in possession of in the foreground.

Next up, my existing PAS components in close-up. Please excuse their grubby condition - they've been sitting around for 30 years.

Lastly, the front pulley, which I thought had a second groove, but on closer inspection is merely a single-groove pulley butted up against the flange behind.

So far the consensus appears to be that I don't require any wiper modifications, but I do require the correct pulley, and I may need to change the track rods. Is that correct?

I think a new fan belt will be part of the eventual upgrade - note how the existing one has "made in UK" on it? Here in NZ this is likely to mean it is very old, possibly even original. I certainly haven't changed it in my nearly 15 years of owning GF148...

Cheers,
Warren
 
You can use the non-PAS track rod, it will fit, it's just not the correct one, and IIRC not so easy to adjust the FWA with the PAS box, which I notice has no drop arm fitted so you'll need one of those because AFAIK the one off the manual box won't fit the PAS box. You can bolt a drive pulley to the rear of your crank pulley.
 
Thanks Pilkie. I also meant to say thankyou for the offer of sending stuff out in your mail run. Coincidentally I spent 6 years growing up in Ruakaka, not far from Waipu of course. I attended Bream Bay College with all the local Waipu kids. A long time back now, sad to say.
