Here is the pump mounted onto my V8 just before the transplant


See http://www.4wdaction.com.au/forum/viewt ... 5&start=25 for the write up of my powersteering conversion..

Finally got of my arse and went to the wreckers and scrounged around for some 60 series stuff to do a power steer conversion on my 40. Picked up a steering box, Fj55 steering column (even though its 2inch longer than a 40, it has a spline at the fire wall for uni joint). These are the main parts needed so far. I also got drag links, tie rods etc but after fitting up today found out I didn't need them. I also have the p/steering pump from a holden V8 with brackets. All this stuff only cost me $320! The only outlay i will now have is getting the high pressure line made up from the pump to the box (via intercooler which I will just get off a falcon or commodore etc). Low pressure lines I will just use 5/16 fuel hose and hose clamps as its only a return line. I have to chase up a collapseable shaft with uni's to go between the box and column on the fire wall. The wreckers here haven't got one. I dont feel comfortable cutting and welding the shafts I have to make it fit. I would rather keep it standard parts.

This is how it all looked before I started...


This is the 60 series P/Steering box. These are all the same from the 60 series right thru to the late model 79 series ute. So readily available for this conversion.


Here how the 55 Series steering column looks. It has a spline on the end which allows for the uni-joint to slide on. When changing columns the 55 is slightly longer (will show in later pic) but only by a couple of inches, the plate that bolts to the firewall has to be swapped from 40 column as the 55 is different.


Here you can see that the 55 shaft is a couple of inches longer and the column cover sits out from the dash a bit further.


Here is the P/Steering box vice griped in place. I made sure the pitman arm balljoint was positioned directly in line with the position of the old tie rod from the dampner plate to the left side. That way when the link pushes or pulls it will run parralell with the tie rod from wheel to wheel. The draglink from the pitman arm to the other side is just the one used from the old box to the linkage with the steering dampner on it. I unscrewed the old one from the ball joint on the left side and removed the ball joint from the end of the link I was going to use, then just screwed it on. Using this quite simple method it allows all FJ40 ball joints to be used.




I still have to make up a strengthening plate up to go between the box and chassis and also a backing plate for the other side. I will hopefully get all this finished and stuff before I go back to work on the 8th of Jan. Will post progress up here as I go.

The sreering is better nut but still lots of slack dont know if it may be the steering damper.
