Steering Column Extension

[RAYLEE29]

Personally i would say that 19mm x 1.6mm was a bit on the trust in god side of things especially when the item you are extending is around the 16mm dia solid

hmmm, isnt that part of the steering rod suppose to be colapsible? mine is going to(has to according to the law here in Sweden).

the collapsible part is in the upper section of the column between CP16 & the steering wheel, & also you have the coupling at the rack end & most folk have a coupling fitted just below CP16 so this all ensures that the steering column would deform in the event of a head on impact.
the extension part is purely just that "an extension".
not sure of the rules in Sweden tho

What's the wall thickness of the average propshaft? From my long ago college days a thin wall tube under torsional load is not much weaker than a solid bar of the same material and outer diameter. If I recall correctly the OD is of greater importance than the wall thickness.

That said I am a firm believer in Victorian engineering and would probably use the thickest wall I could find!

Im using a bit of 25mm od 3mm wall seamless for mine
but some people use 16 guage erw for front wishbones!
so its personal choice at the end of the day
stronger is safer
even formula 1 guys get it wrong sometimes (No names I dont want to get sued) but we all know

Could do with some advice again, my steering column is the adjustable type and my downlink that I need to extend is the 2 piece extendable type.

Do I need the extendable part of the lower downlink? or can I just remove it and join the upper UJ and the lower rubber one?

Thanks again.

sorry you,ve lost me a little there

what i did was to buy a splined shaft from Rally Design, cut it in half & fit it into the rack end using a new "group 4 " coupling, the original rubber end shaft was then cut to remove the rubber bit then that went into the extension i made, so the triangle part(rubber coupling) is now fitted just below CP16 which makes it easy to remove the steering column without needing to remove the steering wheel section,
i have a few pics if that would help?

Hi Andy sorry for confusing you, my lower downlink is like this one below not sure whos picture this is.
I was wondering if I need to include the triangular clamp piece (looks like 2 wings) just before the extension tube is welded on, and after the UJ joint on the left.



Cheers

the way thats done in the photo is precisely how i,ve done mine, the reason i did it like that was to make the column between Cp16 & the steering rack removeable without needing to remove the steering wheel or the rack itself, & also the part that clamps onto the triangulated part that is just below Cp16 has a locating pin too, so it all more or less keeps the original spec of the sierra column which must be good for the safety aspect of having a deforming steering column in the event of a frontal impact. also it helps with installing the engine as its easily removed by undoing just 2 bolts.
