Sorry mate I'm a bit lost, you made up a new pipe to replace the original long routed pipe that cools the fluid?

stevieturbo

I thought it was pretty obvious what I did seeing as I took photos of what I made ?

I made adaptors to fit into the rack to allow the fitment of -JIC/AN fittings.

After that you can use whatever hoses or pipes you want as long as they are suitable.

I understand that, but your previous reply seems to make no sense to me.

My question was, if you quip the rack, would there be any reason why you could not quip both ends of the long original cooling pipe, to keep the cooling capacity. You answered you can do either?

stevieturbo

The cooling pipe is low pressure. So in reality, putting silly looking stainless steel hose on it would be an absolute waste of money. It would not need any fancy ends, as hose would simply push on.

Obviously if you welded threaded ends onto it or adapted it in another fashion, yes you could use any style of hosing that mates to those ends, be it stainless or otherwise.

But a long length of any flexible hose will have negligible cooling effect compared to a similar length of solid metal pipe. Preferably aluminium if it is for heat dispersal purposes

JamesH

Cheers, so it is worth keeping the solid pipe in the system then

stevieturbo

That depends if you have an issue with the fluid overheating or not

You could add a proper cooler, larger reservoir, reservoir with a cooling loop inside, an external cooling loop.

You can do whatever you want no matter what way you do it

instead of drilling and taping like the grp a racks could you not weld on suitable steel aeroquip fittings? welding in short burst to keep heat down,

What size would be suitable for the fittings? -6 seems about right to me

can you take the rack apart or is it pressed together etc

Thanks

hi marc i made adapters that on one end were the original fittings ie o rings etc and on the other - 6 male all one piece just replace with the pipes and screw your goodridge fittings on the end made of stainless

look at the pic i put up
thanks mark

stevieturbo

Same as mine. Best thing about it, it means the fitting can swivel, so easier to fit hoses without putting any strain on anything, and virtually no chance of anything working loose.

How are the fittings held in the rack then Mark? as it isn't threaded or anything, i have never had a cossie and just have a new rack so no original pipe work!

Are they held in via a circlip or similar?

Thanks
Marc

its like a double hourse shoe with a 6 mm hole and a bolt goes in that 6mm thread in between the two holes marc
mark

stevieturbo

You can sort of see the retaining plate on mine that holds them in. Just held by a single M6 bolt in the middle.

Stevie - I can just make it out I think, il have to hunt one of them down then from a breaker, they same 2wd and 4x4 racks?

MARK - Would you be willing to make 2 more dash 6 adapters for the steering rack for me please?

Thanks
Marc

MK MOTORSPORT

iTrader: (1)

hi marc ,that plate comes on one of the pipes ,i made a new stainlees one to match fittings marc

yes i could make some more mate

thanks mark

Mark how much for the bits to do this conversion?

M K

iTrader: (9)

i also need to quip the supply fitting from the electric power steering pump,

Here is the original fitting with a similar style o'ring fitting as the cossie rack except this one is compressed as the nut is tightened,







Mark - could you make this up with the original fitting thread as shown in the pic on one end and -6 on the other end? you would not even have to make the o'ring fitting as part of the threaded fitting for this as i can just cut the original down and insert it in the end seperate,

If i can find the thread size of the original there may even be an adapter out there already,

M K

iTrader: (9)

Just checked and the saxo pump fitting is m16x1.5 so all i need is an -6 to m16x1.5 steel adapter for Ł2.88 from think automotive and insert the standard cut down o'ring fitting piece in the end as shown in the picture above and thats that part sorted

Unfortunately the return will have to be a jubilee clip as its just a plastic tube that is moulded as part of the electric pump resevoir and takes a standard push on hose so cant quip that

jon@work

iTrader: (5)

Marc - instead of using the standard 'O' ring seal, couldn't you use a dowty or copper washer to seal the M16 adaptor to the pump ?

M K

iTrader: (9)

i think a normal pump runs at about 90bar so not sure if a dowty seal would be ok?

jon@work

iTrader: (5)

if you have a look here (for example) :

http://www.cejn.com/Products/High-pr...ssories/Seals/

the maximum pressure for their dowty seals is 100 MPa, or 1000 bar

M K

iTrader: (9)

Jon - As the o'ring pipe piece that slides in needs nothing other than a claen up and shortening il just use that, plus I know this will work,

Mark @ MK Motorsport is making me up the other fittings for the rack end

M K

iTrader: (9)

Well i got my adapter today from THINKAUTO for my electric power steering pump from m16x1.5 to -6 and it already comes with the pump o'ring seal part of the standard fitting



Get them here for Ł9.94 plus vat and del

What's to stop you just welding steel -6 weld on fittings straight to the rack with some really neat tig welding? Short bursts to keep cool, don't think there is anything close enough that would melt is there?

stevieturbo

Firstly, welding steel fittings to an aluminium rack might prove tricky.

And even if you could weld it, why make it so complicated and difficult by actually doing so ?

When a simple fitting can be made up that just slots into place.

M K

iTrader: (9)

didnt realise the rack was aluminium, But surely aluminium fittings could be used instead and i only thought of it because the rack is new and on the bench as the car isn't built yet and i have a friend who is a fully coded welder so would be a piece of cake for him to do

Any other reason why not to you can think of?

MK MOTORSPORT

iTrader: (1)

if you didnt want to put these adapters in mark ,you would be better tapping the holes than welding to cast housing mate

thanks mark

M K

iTrader: (9)

Have you had a chance to make them yet mate?

Thank
Marc

MK MOTORSPORT

iTrader: (1)

yes mate ,but if your going another way ,no probs

thanks mark

M K

made my fittings at home on the lathe and am happy how they have turned out



What i want to know now is regarding hoses!

Mark - you said you have used normal braided Aeroquip hose and alloy fittings and had no problems but when you read up on it online especially via Earls website is says you should only use steel fittings and special hose due to the 1000psi+ pressure you see in a pas system

Obviously power steering fluid is highly flammable and could be disaster if it burst,

Does anyone else apart from earls sell suitable hose?

Thanks
Marc

stevieturbo

Whilst I use Earls myself, they are probably being 100% safe in their approach.

I think mine is about the only car Ive ever seen that has used such hose for PAS lol Every other car that has made their own pipes just use regular Stainless braided hose.

Although wouldnt really have matter. I wasnt using stainless hose no matter what

M K

iTrader: (9)

Think maybe I will get Pirtek's to make me up some fully swaged hoses, as high-pressure stuff is the norm for them ok it won't look as nice but will be safe and probably cheaper

stevieturbo

I'd say their hydraulic hose would be more than adequate. Probably stronger than most stainless stuff.

I'd say it would look better. But then I just hate that stainless stuff lol

Overall though, for all you need even the Earls stuff isnt expensive.

You'd only need one 90deg steel -6 fitting and a straight -6 and slap a banjo onto the pump to connect to. And then a short section of hose.
The Earls stuff is handy purely because you just make it yourself.

There is obviously no requirement for pressure rating or steel fittings on the low pressure side. Just hose that is suitable for PAS fluid. Although most petrol style hoses will be fine.

M K

iTrader: (9)

Well I ended up ordering the proper Eaton Aeroquip high pressure hose rated to 2250psi along with 15ft of hose,

Least I can be safe in the knowledge that the whole lot is done in the proper hose with proper steel fittings

I ordered enough to do all fittings even the low
Pressure side, plus I have steel through bulkhead adapters as my electric pump is in passenger footwell so bought 7 90degree fittings in the end and 15ft hose to be sure Im not short.
