Steering column width?

[scottg]

Can anyone help? I understand the steering column has 29 splines on the NSX where the steering wheel is fotted but does anyone know the width of the column at this point?

Hi, Scott.

Could you be more specific (ideally with a photo) indicating exactly which measurement you want to know?

You can download and edit these photos.

Also, what kind of accuracy level you are looking for because if you are manufacturing something,
you will need to specify it on the drawing and my measurement may not be accurate enough for your purpose.

I don’t have access to the actual steering column unless I remove my existing Type-R steering wheel from
my NSX but I still have my old original one in the storage.
If the required accuracy level is not that high,
I can measure the mating slot on the steering wheel side where the column is inserted.


Alternatively, I think Sudesh is selling his Type-R steering wheel boss in the For Sale section.
If you ask him nicely, he may be able to take some measurement ahead of me......

Not sure what is your objective but if you are replacing the steering wheel and
manufacturing some sort of boss or spacer, I do recommend using the Type-R boss (from Momo) because
it has built-in crushable mechanism for your own protection.

Personally, I will never install aftermarket solid metal steering boss or spacer without any sort of
built-in crushable mechanism even if the steering column will move forward and drop down under severe impact.

Hi Kaz,

I contacted Sudesh to buy the boss within a few hours but someone had already reserved it. He said he may have another but havn't heard yet. In between times I had already e mailed Momo and they have replied to say they dont have a boss listed but if I confirm the spline number and diameter of the end of the column they will see if they have something that fits. If the type R boss is Momo as you say then do you have a Momo part number?

On another note the fault with my brake/TCS/ABS lights was an earth in the end, thanks again for all your help and advice.

Kind Regards

Scott

Hi, Scott.

It’s Momo #4916.
Type-R OEM steering wheel requires extra three fixing holes on the boss and that’s the difference from standard Momo #4916 model.

Thanks Kaz,

So in effect a standard 4916 hub will do the job as the extra holes are unused?
