Best contacting Alan at OKA. He should be able to tell you straight up what the difference was/is. He may also help with documentation.

I too am looking at upgrading the GVM and GCM when the engine conversion is done, dad will be doing it through an engineer he knows. If i can i'll find out the process and any probs in doing it.

How did you guys go at increasing your GVM to 6000kgs. I took 356 over the weighbridge recently and it came up 5900kgs fully loaded. I too require some documentation for my engineer to change GVM. Did any of you have any luck with the documentation and if so can you point me in the right direction where to acquire it
Thanks

Peter Davis replied the topic: Increasing GVM
You need to get the spec sheet from Allan of your Oka and another Oka of the same model but with the factory higher gvm. Your oka will then need to match the specs of the higher gvm oka, ie running gear, suspension, brakes, rims and tyres. Rims and tyres need to be at a higher than the rating required, leaf springs will have to match the number and size of the higher speced oka. The contentious item is the front axle rating. Your foot brake and steering should be ok, Hand brake will need to be the heavier duty one if it is the Rockwell transfer case. I hope this helps.

I notice that in NSW that at some weigh stations all vehicles over 4.5 tonne gvm are required to go over scales. Victoria I believe is vehicles over 18 tonne.
Has anyone had their oka put on the shacker?

Re: Weigh stations all vehicles over 4.5 tonne GVM are required to go over scales.
Yes and NO. In South Australia I recently went past a Weigh Bridge with "All Vehicles over 4.5 Ton Must Stop" Sign and I failed to stop, felt guilt and went back fearing a large fine. Spoke to the guys there and told only Commercial Registered Vehicles over 4.5 Ton are required to stop and as I was registered as a private vehicle there was no need for me to stop. This however may be different in other states.
If anyone from other states could find out if this is the same please let me know

for 15 odd years I fly over QLD, VIC & drive new trucks back.
On Dealer Plates, we are unregistered & unrated, unable to carry A load.
we do not have to stop at weigh stations & get another fringe benefit.
I always stop , it gets a bit boring being chased & dragged back to explain all the time,
you loose an hour wile they do all the check ups.
funny, they never apologize for there stuff up!!
they are called Mermaids for A reason.
morel of the story.
we are not yet requested as a commercial vehicle!

Few years ago, when I first bought my OKA I took it to 3 different Engineers for an assessment of what was needed to bring it up to rego standard and what ever else.
The first, who was only interested in finding as many problems as possible to get work, put the OKA on his shaker. Whole truck went into Simple Harmonic Motion, could have shaken it to bits.
Opinions from the second and third engineers were definite that design of the OKA suspension as an off road vehicle with large travel and flexibility make it entirely unsuitable for testing on a shaker. Opinion since confirmed by a other OKA owners/experts.
Interested to know others experience and opinions

Dave H, are you saying that's what you've changed yours to? (6.5T and 9T) I thought 20% extra to original manufacturers specs was the max you could get which would be 6.6T GVM and 8.4T GCM?

#196 is GVM 6,600kg and GCM 9,000kg.
Upgrades required to wheels and tyres (in this case 305/70R19.5) and to springs (in this case 10mm top leaves all round and supplementary coils in the rear).
"The capacity of the Dana axles is adequate".
My engineer also performed braking tests including 15 stops @ maximum deceleration from 60kph while loaded to 6.6T, one after another to check brake temperatures and fade.
Loading for the tests was 2.8T on the front axle and 3.8T on the rear axle.

Thanks for that Peter, I have already upgraded the wheels and tyres and also the spring packs with 10mm main leafs and an extra leaf on the rear, I also have air bags all round. If you have any documentation you would like to share it would be appreciated

Not sure what "documentation" you mean.
The upgrade was made in accordance with the info I posted earlier. Presumably the engineer made lots of calculations (to justify his fee), but I have none of that at this stage. He has done these upgrades before too, starting with #266 that was increased to 6600/8400 in 2005.
Mine also includes seating and tow bar stuff.

So logic would say that i could go to this same engineer and he could sign a gvm upgrade off without all the tests etc based on proof of the same vehicle specs etc. Does anyone know if this is the case? And, are all engineers compliant Australia wide?

Surely you know that when it comes to bureaucracy, logic does not apply.
SA Transport has its own list of approver automotive engineers.
We have some seating modifications (with blue plate) that were done in Queensland. I believe that they are not recognised in SA.
In any case, I would expect the engineer may still want to do brake tests. Up to him.....

I have recently had a conversation with my engineer here in Qld and he is happy to upgrade the GVM with an inspection and a photo of another LT compliance plate with a 6000kg GVM. Paul Nott sent the photo up and I can forward it to you if you wish. The engineer will also inspect the engine install at the same time and include that on the blue plate. This is all happening on Monday morning so I will let you guys know what the outcome is.
Well guys all done GVM now 6000kgs and Cummins motor change signed off as well all for $ 300.00 for the engineer plus the Qld transport fees
