are we to assumme the pitman arm is attached in the correct location on the steering box, or is there a method to check?

what is the best way to flush the system of the existing PS fluid?

Will I need any O Rings etc for the hyd fittings?

Any nuts etc that should be replaced during this procedure?

cheers

Hey serg,

The arm will be correct, there are 3 master splines and 2 of them make the arm face completely in the wrong direction

O rings are generally not a problem, make certain you tighten the clamp bolts on the column unis tightly.

any tricks to getting that column uni of the SB shaft? I see it just has a pinch bolt, but am thinking it may be on there good???

remove the bolt completely, it is keyed to a flat on the shaft. soak in crc and may even have to spread it slightly with a small flat blade screwdriver.

I have picked up some Castrol Transmax Z for the powersteering fluid. I want to flush the system before removal and refitting of the new box. Do I have to use the Castrol or can I use something cheaper?

How much fluid does the system hold?

According to my Defender manual 2.90 litres for power steering box and reservoir. It also says steering box-manual 0.43 litres. So I guess this means the steering box itself holds .43 litres and all the rest of the power sterring paraphernalia holds 2.9 - 0.43 = 2.47 litres.

The book also says the fluid should be ATF M2C 33 F or G whatever the hell that might be or Dexron IID.

Castrol's got a chart showing all the recommended lubricants for all sorts of vehicles but it's too well hidden, can't find it.

Found it!

According to Castrol's site Transmax Z is the all singing dancing fully synthetic Dexron III replacement.

My old favourite Transmax M the common or garden variety Dexron II equivalent has now been re named Castrol ATF Dex II

I've got no idea apart from a GM vs. Ford type thing what the difference is but my mechanic maintains they (Dexron II and Dexron III) are not interchangeable. Don't know if this counts for power steering though

I would have thought a Dexron II type fluid is what you needed ?

Transmax Z was recommended to me by another Landy enthusiest with a 98 Defender. I trust his judgement .

My head says good practice would require the same brand/type fluid used in the flush as the refill, but my wallet wants a second opinion

I think you might be buggered. Not only are you changing Dexron II for Dexron III you're changing mineral for synthetic at the same time.

So what you're after is a Dexron III synthetic cheaper than Transmax Z for flushing purposes ? Now there's a challenge.

Dexron VI ?
