Steering rack from a Mark 1 Escort

[Enoch]

I have been offered a steering rack from a Mark 1 escort. Does anybody know if it will do the job or if it has to be one from a Mark 2 as per the book? I have been told it's only the length of the splined shaft that goes to the steering column that is different but can't find any info to back this up. Anybody know any different?
Thanks in advance.

Not 100% sure .... But I think you'll find that the Mk1 steering rack uses an imperial thread for the track rod ends.

If this is the case .... Might cause you a little hasle when it comes to the steering rack extensions ;)

Sorry, that's the best info I have floating about in that little pea brain of mine :o :)

You are correct Ronnie, the Mk1 steering rack uses an imperial thread for the track rod ends.

That's not a big deal as I would have to make extensions anyway so I can put any size thread on them. Anybody know what size thread they are?
Thanks chaps!!

[Bonzo]

Although I do not have one here to put my thread gauge on .... I believe the thread may be 1/2" UNF ;)

If you are going to machine your own extensions & have the right tap, tis no real drama ..... You can still thread the outer end with a M14 thread :) :)

Checked in Burtons Catalogue 1/2" UNF.

Thanks a lot guys, will have a look through my taps this afternoon and see if I have the right one:) If I don't it's only a tenner to buy a brand new one so I should still be quids in.
Thanks again,
Dave.

There's a very good chance I have a 1/2" UNF tap if you don't have one .... Happy to give you a lend of it when your ready

I'll have a little look after lunch

EDIT

Would you believe it !!??

I got 1/2" BSF .... 1/2" Whitworth but no 1/2" UNF :rolleyes:

Got both sizes of tap, either side of 1/2" UNF though :D

As they say .... It's the thought that counts :o

Thanks for looking Ronnie. sod's law strikes again:)
I will have a look in my stash and buy a new one if I don't have one.
