Took my truck down the paddock this morning to warm the oil before a change. Decided to check the turning circle.
OS to OS of the front wheels was about 54ft or 16.5 mtrs
I run 900x16,s and was wondering how this compares with the other 6x6,s around.

did you try the other lock? would indicate if the stops are adjusted the same

I think you may have mis-read your measuring tape, easy to do I know :)

If we are talking about the same thing (the turning circle), an ex-mil 6X6 Perentie is reported to have a turning circle of at least 17 metres with 750 16s, the 4X4 110s would be around 14m depending on the adjustment of the steering stops

Hope this doesn't sound as pedantic as a moderator :(

Thanks.
How did I buggar that up. Bears no resemblance to what I had before.
Went back and measured the marks.
Anyway, why I was interested was this.
I have put a set of coils as extra springs on each axle going to mounts on the chassis. Not a real good move as I know it must inhibit the load sharing feature.
I was wondering if I replaced the coils with airbags and connected the intermediate and rear on each side I would still have load sharing.
Then I wondered if I could isolate and pump up the intermediate I could shift the pivot point of the turning circle to the intermediate axle hence making the circle tighter.

The things one thinks about on sleepless nights.

Makes sense, after all, that's what trucks do when they run unloaded.
But, they run fully air suspended. Are you proposing to do the same?

Yes interconnecting the airbags front to rear t gives you load sharing, no jacking the rear axlewont help the turning circle, have someone drive it for you on a tight turn on dusted concrete and you'll see the back axle sliding sideways compared to the centers. The steering geometry is set up such that the theoretical axle about which the ackermans steering geometry is set up is about level with the rear of the intermediate rim.

Ah, OK, Thanks Dave, so wont be gaining anything on the turning circle but the load sharing might be worth it.

As a by the way, We have 30 acres up here if you need somewhere to store stuff. Might be a bit far but.
Catch up sometime.

No, just a bit of a helper to get the rear up.
I had to jack the front up so the starter motor on the chev V8 clears the drive shaft.
