Hi Guys, I'm working in Newman at the moment and I phoned Chris, got the location of said OKA and took some pictures.
A sad sad sight :-(
Here they are:

Wow, that doesn't look like it was in a vehicle generated fire, more like it was caught in some sort of inferno - bushfire maybe? How hot do leaf springs need to get before they invert? As you say Bob, a sad, sad sight.

Looks like it could have been an electrical/fuel problem contained to the vehicle looking at the surroundings as nothing else is burnt?

OKA Lost did not burn where it now sits.There is a drag mark in the birt under the tow hitch where it was unloaded from the tilt tray and there is no ash or rubbish from the fire on the ground underneath it. One of the operators of the grounds where it now sits told me they had never seen it before it burnt,they arrived one day to do some work and there it was, as is.Burnt elsewhere. Chris

It wouldn't have been moved very far in that state and if was an internal fire I doubt that it would have burnt so completely from the ground up.

I don't think Newman is a real bushfire-prone area so my thinking is some sort of industrial fire (caught in pool of burning fuel?) or maybe a fractured gas cylinder (there are striped burn marks on the RH side).

Really sad no matter what the cause, imagine how you'd feel, brand new expensive vehicle, doing a big retirement trip and suddenly it's all gone. I hope the owners escaped unscathed.

I have seen a couple of tractors burn to a similar state on bare ground (both had electrical faults under the cab that ignited stubble residue)

Driver's side looks like it was hotter.

My money is on Spinifex or an electrical fault.

Cheers, Tony

Suprised the springs have inverted.

I am not a metal or fire expert, but it looks like the springs was made with soft metal. But I am no expert.

Lobo,All you need is 500 degrees C for steel to be malleable that is not that hard to get in the centre of the fire,in my wood fired oven I get the centre of the fire to 650-800 degrees for an hour and that radiates to have the whole oven at 350-400 degrees
Cheers,Joe

After enquiries in Newman, electrical fault was mentioned as being the cause Chris, better check the wiring on OKA 22 thoroughly I guess.
How is the eastern side Chris?

Cheers Joe, I thought springs would need a lot of heat to bend, guess 500 is the number.

That is some disaster... could only be gas cylinder or two and fuel to do such a hot burn..I notice on the image the rear wheel is 6 studs...as well as ‘barn doors’ at the rear.. that could narrow the field so far as identification is concerned...I have yet to see anything other than 8 stud wheels / hubs..
Was an LT in town last week with 22” wheels... but still the normal 8 studs.. I wouldn’t like to have to find a spare..
Cheers,
Nobby.

Crikey Nobby, you've sure been digging in the archives. :)

Fires can start for a variety of reasons, I don't know if an 'official' cause was determined in this case.

As for the wheels/axles. The original NT has/had BAE housings/axles and they weren't really very good. In fact they were renowned for failure. I don't know how many diffs/axles Rudi & Suzi went through in NT#1 but it was several. It may be that the 8 stud variant you saw was an NT with a Dana 80 'upgrade', Paul Nott has done several of these.

I'm told that Dean has this all sorted now and his replacements/spares are up to scratch.

From memory, the early NT's had 'normal' one piece rims with later models having the 'composite' rims as shown in the picture. A big benefit here is that the rims bolt together around the tyre so no special tools are needed to change a tyre. The downside though is that forgetting to air down before disassembly can lead to having your head removed as the rims separate under pressure.

Another major fail with these rims is that the tyre valve assembly comes from the inboard side of the rim centre and pokes through one of the gaps to the outside of the centre disc to allow inflation. On a previous Oka-ing Adventure an NT with these rims became bogged in river gravel and whilst trying to drive out river gravel was picked up in the inner rim and spun with the wheel neatly (well, not so neatly) guillotining the valve stem assembly between the inner rim and the brake caliper. This happened on two wheels, fortunately the NT had two spares. Unfortunately the driver had to leave the group and drive several hundred Km's into Port Headland to find that there were no suitable replacements available locally. Eventually replacements were found, 6 in all and that was the lot in WA. All were purchased. I would never consider using these rims for any serious off road work.
