Post subject:  Collapsible steering column requirement
Hi All,
Just got off the phone with the engineer regarding my UK built 1972 mini. To put it on CVS or full rego all applicable ADR's have to be met and engineered, one of them is a collapsible steering column. I assumed it would have one being a '72 model but maybe not in the UK at the time? They were behind us on safety.
What would my options be do you think? Did the 1972 Aussie Leyland mini even have a collapsible column or did it meet the test requirements without one? It's thrown me a curve ball.

yes, as far as the ADR at the time is concerned, '72 mini clubman has a collapsible steering column. The column bends up towards the windscreen at the bracket... it passed the same ADR until production finished in '79 - your car should have the same column

It met the requirements without what we now call a "collapsible column". The steering column and wheel pivots up after a front end crash. I think all Minis and Mokes built in Australia right through the 1970's had a solid steering column and met the ADR's.

Show your engineer the crash test photos done for the Clubman GT - viewtopic.php?f=2&t=85906

Edit: Simon beat me to it. :)

Thanks, so how can I tell if it has the same column as a clubman? If I put a clubman column in it would it fit and function in a crash the same as a clubman. Stuff this UK built thing! I can see the engineer making me put an actual collapsible one in! $$$!

Simple answer is yes, a solid column will function the same regardless of the slight differences between various models. The principle relies on the swiveling of the steering rack in its U bolts at one end of the steering column and the retention of the column outer tube to the parcel shelf by another swiveling bracket.

Here's some examples of the steering columns fitted to the Mini and Moke during the 1960's and 1970's. All are solid steel and all met ADR when installed with the original factory brackets.

P.S. The Moke one went into the 1980's and still met the ADR.

Thanks mate, I'll have to show him this info and cross my fingers.

I can give you the relevant pages of the Mini parts catalogue showing the solid column if that helps, but just talk through what's been said here first. True collapsible columns with several sections and joints linking each are not required for a Mini to meet the ADR. You are on firm ground. Don't be bullied into it.

Here's the ADR applicable at the time - https://infrastructure.gov.au/vehicles/ ... es/10A.pdf

This update didn't apply until January 1973 - https://infrastructure.gov.au/vehicles/ ... es/10B.pdf

Have a look through this recent thread and you'll see quite clearly on the ADR plate that the Mini meets ADR10A and later ADR10B.

And the UK mini should be identical in any way relevant to the ADR compliance and crash test, correct? All UK and Aussie steering columns and mounting and everything are identical right?

The design principle is the same. The parts may not be.

Did you talk to these guys? They put overseas built cars through the system all the time.

I haven't yet mate but will give them a call and maybe they can talk to my engineer and talk him around, you guys know mini's pretty well and can vouch for them having the same steering column and complying. Cheers

Thought of another one that might screw me over. Burst proof door handles. It has the old style push button ones not ones like the leyland mini. Does this mean they won't comply? How the hell can I get around that one!!

I’m not familiar with Uk minis but maybe they are burstproof. If the part on the body is shaped like a loop then they are probably burst resistant.

Some photos. Maybe it has something to do with the push button instead of the flip handle like the Leyland, i understand something to do with doors coming open during a rollover. These ones work like any door handle, half a push half unlatches the door and full push opens it up like any normal car. Not sure of the burst proof definition.
Basically my chances of CVS or full rego are ‘hinging’ on these doors. No CVS means no comfy Alfa Romeo seats which I’ve just bought and no serious performance mods :(

My understanding is they are burst proof type. Like a modern car the door latch actually grabs onto and around that loop. The door is designed to stay latched in an accident. The other requirement I think was that the outside door handed needs to not protrude like a hook which is what the old mini handles were like. That’s why all the cars in Australia in the 70s suddenly got slim or lift up handles. It will be up the the inspector I suppose. Maybe those ones are ok.
