steering rack extensions
 
hi all, i have a mk1 steering rack & will be making the extensions tomorrow & was wondiring if the drawing 5.36 on page 76 is the right length for a non modified mk1 or mk2 or is it for the ideal length of 533? does anyone know the total length of the steering rack (cc balljoints)?
cheers

Can't help with the total length as mine isn't installed. But are you aware that the MK1 Escort has a different (imperial) thread. Apparently.

I believe as londonsean says that the mk1 rack has an imperial thread so would need different extensions (internal thread imperial/external metric to suit tre)

Most people buy new mk2 racks from rally design.

The book extensions are for a modified rack so are too long, but the alloy extensions from rally design are perfect for the job, as are the alloy rack clamps they sell (im not on commision honest!:D)

hopoe this helps

ps. do you want rally designs phone no. ;)

i cant find in the book where it says whether the extensios in the drawings are for the modified or non modified rack ! did i miss something ? can you buy modified racks off the shelf? :confused: as far as i know the mk1 & mk2 everyone buys are the same length . so how long ahould the extension be?
Cheers

I couldnt find a modified rack off the shelf so have a new mk2 escort rack.

My original extensions were to book spec and were definately too long.

i havnt got the length of the ones that i used to hand at the moment but if someone doesnt come along with a dimension for you in the mean time, i will measure mine for you tommorow.

I think they need to be approx 30mm shorter each side if i remember correctly but will confirm tommorow.

Hope this helps

If you go onto rally designs website and type in the search box the code DAR024 thats what i used and they are perfect :)

They say that they extend by 120 to 130mm per side

My extensions are 130mm long with a 25mm long external thread and 67mm deep internal thread.

Hope this helps

thank you so so much Mark , that was a great help . i thought they kinda looked too long when i was making them but i can easily shorten them to 130.
thanks for the help
