I am going to convert my 'arm-strong' 12J 2.5 NA to power steering, if possible. It is a bit of a bear to maneuver at low speeds in the woods and I am not getting any younger. I know that some of you purists will scoff, so scoff away!

The truck is a LHD 1995 ex MOD with am MA serial number.

I have tried to source a used PAS system from a Discovery, but there is not much to pick from on this side of the Atlantic and their condition is sketchy at best.

If anyone has photos of a 12J engine with power steering, I would appreciate seeing them.

From the information that I have been able to get on this forum, I will need a NTC9070 pump and the NTC1581NOR steering box (this is Paddock's number).

I have the bracket to hold the pump to the side of the engine. Also I have found the part number for the pulley for the pump - ETC5783.

What other bits will I need? Any parts numbers would be appreciated. In particular puctures or part numbers for the three hoses that I will need.

I can see the parts on this page for the hoses and reservoir, but the page does not give part numbers.

The PAS box is in! Here are some pics of the installation should anyone else want to do the same.

First shot is the bracket for the pump. The Alternator fits on top.

Second shot is the comparison between the old 'armstrong' box and the new box.

Third shot is the location on the frame where the new box will go.

Here is the new box in place.




The PAS pump. NTC9070. with pulley attached. Do this before attaching the pump to the bracket unless you are a masochist!

I had to drill new holes in the pump mounting plate in order to 'clock' the pump 45 degrees. Otherwise the hoses would be either blocked by the pump mounting bracket or the frame.


The flange that attached the steering box to the tie bar is thinner than the one on the manual box and I was too cheap to get shorter bolts, again. The reservoir mounting bracket is home made as I could not justify £58 for the proper bracket.





Final installation with alternator in place. PAS Belt ETC5815 (Dayco 13A0725C) was too short so I used NAPA belt 7280 which is a narrower belt and works just fine. The shiny coating is Rust Check undercoating as this all will get muddy soon. I'll take the drop arm from the old steering box to have as a spare.

Cheers,

Colin

That's a cracking job, it looks better than the factory!
Congratulations on getting it sorted.
