Power steering conversion - advice needed (1 Viewer)

[sadam_husain]

I have a variety of different links and arms and tie rod ends etc.

At the moment, rough measurements of the different arms suggest I will be using the following:
60 series relay rod
70 series drag link
60 series (knuckle) arms
60/70 series tie rod ends
70 series relay rod ends
80 series steering box/pitman arm

Looks like I'll have enough adjustment to make all of these work without cutting/welding/re-tapping threads.

I have a 60 series and 70 series pitman arm that I can use (I'm assuming splines stayed the same) if I need to.

If you use 70 series relay rod and drag link with 60 or 70 series knuckle arms everything is the correct length you don't have to cut anything

the tie rod ends wont fit the 80 series pitman arm so you'll have to use the 60 or 70 series pitman arm on the 80 series steering box (splines are all the same)

dunno what the aussie prices are but in NZ we pay $45 for a 70 series drag link or relay rod complete with tie rod ends from Toyota including freight ex japan

I picked up all the linkage arms very cheap. I think $50 for all the 60 and 70 series stuff including the 60 series box and pitman and 70 series pitman...

Good to know about the taper - will probably use the 70 pitman (one it's flatter but mainly because it is loose - the 60 series pitman is on the box)...

One question I have is:
View attachment 940174

In the photo above, the 80 series intermediate shaft has a rag joint/uni joint combination.
From looking on eBay, the rag joint is compatible between 40 series and 80 series... Can anyone confirm this?
If they are the same, it looks like the rag joint on the 80 column is on a spline - could you take it off and put the uni joint on the spline and then mate the rag joint to the 40 series (non-removable) rag joint?
This would mean you don't have to cut the rag joint off and re spline the 40 column...
Knowing my luck the will both end up male ends (or female ends) otherwise I'm sure someone would have done this already....

No, the 80 series rag joint is a different size, that's why you cut the 40 series rag joint off and spline the 40 series shaft, that gives you adjustment?

That's the info I needed - is the 80 series rag joint bigger? Is it better to use the. 80 series rag/uni combination or to just use the 75 uni?
By doing an 80mm long spline (is it 36no. spline?) how much adjustment do you get ?

 

[watrob]

A rag joint reduces vibrations and also reduces flex up thru the steering column.

 

[Mustangstolli]

Ok. Getting some prices to cut a spline on my column.
Does anyone know the spline count?

 

[watrob]

Take the uni joint along with you and they will count the splines per mm.

I have a 60 series box conversion on my BJ 42 and love it

Finally got the grinder, drill, punch and baby sledge hammer out on the weekend.
If anyone tells you the rivets are easy to punch out they're taking the piss
Cut the head off the rivet and tried punching them out. Took a few chips out of the paintwork with the punch being dislodged by the sledge.
Ended up drilling the rivets to the chassis - that made it a bit easier!
Decided to use an 80 series box due to the larger internals, future parts availability and stability at freeway speeds.
Used G-clamps to hold it in position and trimmed the inner guard.

There is only 5mm of clearance between the uni bolt and the shock tower.

Is this enough or should I space the shock tower out by an extra 6mm?

 

[Mustangstolli]

Due to the width of the shock towers and the position of the steering box, the shock is angled with a slightly backward lean.
As I understand it, since the shackle is at the front, it is meant to have a slightly forward lean.
Is this going to be an issue? It's a pin type shock mount at the top - will this help with alignment?

Where is the best place to source the bearings for the steering column in Australia?
All my local bearing places don't have any with the sizes 3/4 ID, 1 3/8 OD.

Try a law mower repair shop. It's a standard flanged bearing for ride on lawn mower wheels.

I've posted the part number in another one of my posts. Will try to look for it but if you search on mud I got it from another post as well - might have been posted by twisty and a few others.
