Steering rack size

[Chris Gibbs]

Just to clear this up.

Hopefully.

The dimension of 533 between the inside track rod pivots in figure 5.34 is an absolute ideal. This will require the rack to be shortened but it's not really necessary, the prototype has a standard rack and excellent handling.

It also has rack extentions to the dimensions in the book. Which is a bit of a puzzler.

I've had many people comment that the extensions are too long, but I know the prototype has a 2.9 turns Escort rack from Rally Design and book length extensions. So I'm at a loss

In short, I would use the standard rack and alter the extensions length to suit.

Cheers

Hi
As suggested by Andy & Ronnie I have shortend the extension by 13mm and it seems it is sorted. Many thanks guys.


One last Q do I need to put in the locking nut on the steering rack as well as the on the track rod ends?

glad you got it sorted Axle,

i only have 1 locknut on each end of the rack....between the rack thread going into the extension bar..

one last thing.... as you have shortened the extensions just make sure that the threads of the rack & TRE go fully into the extension bar, ....what i mean is...make sure you get a good "bite" of thread when all connected.

cheers

Hi Andy

Thanks for your input, I certainly would not have it sorted without you. Another Q to educate me, if the thread part of the rack is going to be fully locked into the extention part, should not the locking nut be on the track rod ends?

Cheers again

I got locking nuts both sides of the extension

I definatly think you need lock nuts on the extension and the TRE.

Without the lock nut on the TRE the Extension + Rach end will spin and could alter the track, or at worst wind out and drop off.

I say 2 IMO..
