Steering column Extension

[flyerncle]

Ronnie is defo right,it's a complete assembly with the rubber doughnut.

RD bits and pieces are better.

I guess you would need the Escort coupling & shaft

Would imagine that the Sierra coupling has a spline one end & a triangular bit at the other .... Better suited to joining the extension shaft to the exhisting Sierra triangular lower steering column ??

Not 100% sure on that though .... If I were to have a gripe with Rally Designs website, it would be that there is not enough product information & the images could be larger/better quality

To do a real fair dinkum job, I suspect you'll need, 1 X Escort coupling, 1 X Sierra coupling & 1 X Extension shaft ( A quick call to RD would confirm this ) .... Soon starts to get expensive

If it is of any help to you James,
I belive I have a spare, original Sierra rack coupling here that is still serviceable.
Just need to double check the spline size.

Fogive me James, I think I am being a little bit dim today

You probably have a coupling like this on the end of your column ?



If you have, I guess the most low cost way of doing things would to do the following.

Cut the pice in the photo, midway in the round section ( Circled )

Extend the shaft using some suitable, thick wall round tube.

One end should then join onto the steering shaft & the other end should fit into the triangular end of the Sierra type group 4 coupling.

Still best to check with RD to see if this is the case though

Now I'm confused lol

that's what I have

Hi James

I'll post some pictures up later once I get out into the workshop

I am guessing that your steering rack connector is the larger splined power steering one .

The picture I posted was the top section of an earlier non power steering top section ( Going spare if you need it )

I will check the fitment of the spare lower section I have & get a photo up later

Hopefuly I will be able to make things a little clearer for you

Here you go James

Perhaps this picture will help



Bottom of the picture shows the steering link assembly as fitted to the Sierra.

Part A fits to the end of the steering shaft ( Wheel side ) & part B fits to the steering rack.

At the top of the picture, you'll see an extension I made by simply cutting part B in half & extending with a piece of thick wall tube .... Bit crusty now but it was only made as a temporary thing to allow me to move my build about & sort out any clearance issues

Now here's the big if.
Assuming the Rally Design Sierra group 4 coupling has a triangle on one end & the other end has a suitable spline to fit the Escort rack !!??

You could do away with part B.
Cut part A in half & extend to the length desired.
You may have to remove the flat tang from the end of the triangular peice in order to engage it into the RD coupling if it proves to be suitable for the job.

I hope this helps to make things a little clearer for you

These are the parts you will need from Rally Design.

Sierra Column Coupling > Escort Spline
[RD850]
Group 4 Coupling - Forged Steel
[RD820F]
STEERING COLUMN SHAFT
[RD849]

The sierra column coupling fits the end of the sierra column as it has the triangle fitment.The column shaft will need to be extended as its only 400mm long and then the group 4 coupling will connect the end of the shaft to the escort steering rack.
