Hi,

In the process of complete rebuild for my 1985 2.5 TD 90.

It currently has a 2.5Td with no power steering.

I don't intend to change the engine (just yet) as it was rebuilt 20,000 miles ago and I want to give it a run for its money before I upgrade to a 200TDi.

i want to fit power steering and would like to confirm the requirements.

I have been told it is a case of sourcing a PS pump, hydraulic hoses and a steering box.

Can you confirm if the above items are all i need and do they have to come from a 90 or will steering box, pipes and pump fit from a 200TDi Disco?

Thank's in advance for your help.

Best regards

Grant

Steering box from the disco will fit fine. so will the reservoir, and possibly the pipe from the box to the reservoir, but the other two (box to pump and reservoir to pump) might well be different. as the pumps are different between Tdi and the old TD, and in a different place, the pre-formed metal pipes might not fit (although with a big enough hammer they might be able to be made to fit!)

If you have the disco to strip, then if you can get all the bracketry you might be able to make the Tdi pump fit the TD, and when you upgrade to a Tdi later on, the same bracket should fit straight on.

Disco PAS pump will bolt onto your engine ok - but you will need to lengthen/modify the pressure pipe from the pump to the steering box. The pipe exits the pump at the rear and the one I fitted - fouled on the engine mounting. The pipe itself was too short and slightly the wrong shape too. The hose can be lengthened quite cheaply by any hydraulic hose place, and with care the steel tubing part of it can be re-bent, although it looks a bit messy.

Where I wanted to put the oil cooler on catflap meant that the pipes were too short and the wrong shape. I tried to bend the pipes, but they were then creased and looked bad. Fortunately I had another pipe and did it like these pictures show.

The original shape of the pipe, and where it needs to go.



I removed the bends, straight bits, and the end to make a 'jigsaw'



Then I used the appropriate bits to construct a pipe of the exact correct shape.



The welded steel will rust quickly, so you will have to paint as well.
The inside of the pipe will have developed loose scale and carbon particles due to the welding, so you will have to flush then through before fitting them.
Oil cooler pipes are lower pressure, but I would do it this way to a PAS pipe as well if I needed to.

Hi Les,

Just realised I hadn't replied.

Thanks again for your help.

How much would you roughly expect to pay (2nd hand) for the steering box and pump?

cutting and welding up a pipe?!?!?!

why not use a flexi with a connector for the whole lot?
