Removing airbag wheel


Recommended Posts

I found somewhere that sells spacers for the OE steering wheel as I really need to bring it further towards me. (Only 24 or 32mm)

How easy / safe is it to remove the wheel?

DIY job or let a garage do it?

Thanks

@Rancid: did you use the info I gave you to order the spacer, ie Eltech ? regarding the airbag removal, it can be a DIY job... the one thing to remember is to disconnect the battery !

Yes, will be ordering some shortly.

Thanks for the link

Using these -

After just reading about splines, and springs and things that have potential to take yer eye out, I think I'll get a pro to do mine... :)

 

Will let you know how it goes.

Rancid,I consider myself fairly competent to tackle most jobs, but so glad I decided to get specialist to remove my OE wheel and replace with remove-able Momo.

I watched him do it and it was a pig of a job, took him all morning and he knew what he was doing.

go with the Pro!

That's just fine

IMG_0245.JPGAll done.

Took about 35 - 40 mins to do.

Looked like the worst bit is not busting the spring in the column (think it winds/unwinds the electrical wires for horn / airbag).

Needed a centre punch and hammer to loosen the wheel, and the spacers fitted bang on.

I've had 3 x 8mm spacers fitted and the wheel now clears my leg.

Obviously the indicator stalk is a bit more of a reach, but being a seasoned BMW driver I don't use them anyway.

Chap called Jon Saunt in Leicester - well known from his days at Storm Lotus / Stratstone Leicester.

Nothing he doesn't know about Lotus and now has his own little business.

So, as I said in George's thread, I'll be trying this with a 30mm spacer, once I've sourced some longer, high tensile bolts to account for the 30mm. Then we'll see if it can be done without waking the watchsprings.

Thought I'd reply here to keep George's thread tidy..

Not sure why my chap didn't remove the airbags modul completely- I was talking to someone else and only saw him having a slight tussle with the spring.

Was nothing major but needed the help of some long nosed pliers I think.

Fair enough. Many experts develop their ways of doing things, which may or may not be the simplest/easiest way.

By the looks of it there are plugs for each of the airbag and horn connections, which can be unplugged and reconnected afterwards. I could be completely wrong and Jon did it the only way possible.

I'll post with my real world findings...

No worries. When I get the bolts and time, I'll document the fitting.

they also do a 15mm one, but I tried sitting in a car with the wheel 40mm closer than stock and it seemed the better ball park for my legs. Heck I drove the Caterham last night, which really is "Think To Blip". So much space in the SV chassis!

Thats the adapter i've got fitted with a B+G snap off and mom tuner. Personally im finding the steering a touch too close and contemplating the 15mm adapter.

Real world findings are in.

So is my spacer.

As I suspected, there is no reason whatsoever to remove the steering wheel hub. The Momo airbag wheel is attached to the hub directly by 4 socket head M6 bolts. The airbag and horn connections can be disconnected "this side" of that interface...

The airbag plug. the green tab pulls out to release the connector from the airbag module

5mm socket head M6 bolts x 4. The horn connector is a total pain to disconnect. The barb on it is huge, so you need to really distort the socket part to remove it.

Wheel off. That's the hub with connectors. Dismantling any further is unnecessary. Phew!

IMG_0331.jpg.9398b5190006e895be77ac7dc3deda27.jpg

The four small holes that I drilled out, as suggested by the product text on Elise Shop were unusable, because they're too close to the hub (PCD is too small) to line up with the bolt holes. The holes I did use are deeply counterbored to accept bolts with their heads for attaching this part to the hub, then you'd bolt the bagless wheel on using the other threaded holes. To avoid any slippage in use I made some aluminium spacers from tube I happened to have (perfect luck). These are wrapped with tape to give a non-vibrating fit.

Next up, the plastic shroud around the airbag module has a lip that is too small for the spacer to fit into. Fortunately I have a small lathe, so I turned it down to fit.

After disconnecting the battery at the start I gave it 10 mins to fully discharge at the control module and that seems to have been sufficient. Waiting for hours seems to be overkill.

The space this gives me is great. Heel and toe much easier now, albeit I need to learn the response now, which is quite different to the physical throttle link in the Caterham, and indeed seems a little different between DPM modes. I'm going to see how I get on with this setup, with a thought to possibly swapping to the shorter 15mm spacer if I feel that it would be enough.

I remember Elise Shop telling me these hubs aren't a direct fit for our steering wheel, hence I bought the Eltech ones complete with the bolts.

From your pics, it seems to be exactly how mine was done now I think about it.

Apart from the fact that your chap decided to remove the hub and pfaff around with the clock springs. I wonder if that was because he didn't realise the blue/green connector was a connector. If you didn't know that you could be forgiven for believing that the hub had to come off I guess.

As for Elise-Shop, this is the misleading text...

"You can also use this spacer on an Elise, Exige or VX220 to bring the original Elise steering wheel 30mm towards yourself. You will need to drill the thread out of the four holes in the adapter ring. Then use four long M6 bolts (M6 x 35 or M6 x 40) to mount the steering wheel."

I'll drop them an email to explain why that's not actually true and suggest how to remedy it

That blue/ green connector doesn't look familiar!

 

Well, whatever my chap did was for a reason - he's been dismantling and rebuilding every iteration of Lotus for the last 30  years or so ...

But it all works as it should and it only cost me a few quid :)
