Hi People
Well the forum has added more info than I have needed, with positive results...
As I said earlier "the collective input" has confirmed this ... IMO...
I wish to Buy 19.5 inch Wheels/Rims that will take a 285/70 Profile tyre. Ditto...

Do you have any rims to suit?? taking space in your shed ?? I need 6 in total. I have been offered a New price but would rather wait for a second-hand set - this leaves me more dosh to spend on good tyres.

Additionally! - Where do I access studs from?? I removed my PS rear wheel only to discover a #@*& of cross threaded mash of studs. I need 8 new studs and nuts to match. Who is best to purchase these from? Please??

Hi Bony, I can't help you with the rims but I would suggest you go with 305's instead of 285's. The 305's are easier to obtain and are the same diameter as the 900R16's originally spec'd for the Oka and give you more side wall to potentially bag out :) . Kaye and I did the CSR, Anne Beadell Hwy, the Great Sandy Desert and other trips with these tyres @ low to mid 20 psi's and 'lived to tell the tale' with no tyre damage. I won't go into the airy fairy 'bovine excrement' about 71/2 rims will be totally unsuitable for 305's etc, I've heard it all before.

Paul Nott has the high strength studs to suit, original nuts are a bit hard to come by but speak to Paul for options. I suggest you contact him and have a chat 0418125428.

Deano :)

Thanks dean
The front tyres/studs/nuts are 'natural' to say the least.
The rear wheels have a worn/damaged thread at about 4 or 5 threads out from the base. I am guessing this may be because of the wrong nut hence taper that has caused this???
The wheels are genuine as appear to belong to Oka but the nuts may have been introduced some time after!!
When applying the last amount of pressure to firm the nuts up without 'cracking' I have this sudden but temporary slack before it bites again. Never seen it before... Any comment welcome...
Bony
Edit: Appears to have had tyres incorrectly mounted where they have become loose and destroyed the 4th / 5th thread of All 8 studs.

Bony when I was doing my apprenticeship as a truck mechanic my boss showed me how to tension cylinder head nuts without a tension wrench and it was that small give/ slack on the spanner that told you to stop as the stud was on the point of stripping or breaking,this method was used for head studs that were situated in a water jacket and subject to corrosion over time so that probably tells you how long ago it was.
Its possible its giving you the message its about to fail.

Cheers Dave

G'day all,
just destroyed a tyre on 350 and wondered if there are a couple of 285 70 R 19.5 tyres out here. They do not need to be legal and I would prefer an aggressive tread ...they would only be for farm use only . Obviously some where reasonably close handy would help.
cheers

Where are you getting them?
Do they need to be parted down smaller on a lathe?

We use to be able to discuss the weather, before climate change and politics.
Lockers seem to be like discussing religion or politics.
There is the Air locker, the other locker, and the LSD crowd.
So I have no real help to offer.

In the olden days with an LSD, or with an open diff, we used to jam the bakes on and also the throttle.
The effect was the brakes evened out the load between left and right to a large extent.
Usually it was enough to get enough motion in the snow to extract one's self from trouble.
It is probably known as a "Dodgy Diff" approach, but I am not sure if it is well known.

I recall some words in a 70's Ford manuals suggesting using the parking-brake to do the equalisation work.
Of course once it starts digging in, then it is best to stop before needing to be shovelling to China.

My prefered option is an LSD unit on the front axle simply because of problems I have experienced with air lockers not allowing the vehicle to turn when its engaged, on our trip to the Dragon Tree Soak in which we encountered some of the biggest and most difficult sandhills in WA my companions and I had LSD units of various types Dean and Kayes Oka was/is fitted with a Dana 60 Lsd and that would be the better one to use IMO if one can be sourced I know at the time I wanted one they were no longer in production but I believe Paul now has acces to these units but Dandj and myself fitted Spartan Lockers commonly called a Lunch box locker, they are in simple terms a gear type LSD that breaks lock and allows the vehicle to turn then engages again when the steering is centralised. They had good reviews at the time and they worked well.
The only problem I found was when in 4wd at low speed up to around 10kmh there is some tendency for the steering to pull a little one way or the other but as soon as speed is increased it smooths out.
Its a cheap option and i have found it to be a good asset.

I recently fitted an ARB air locker to the front diff, mostly to get the stronger carrier.
It has had a Simpson crossing since and seems to operate as advertised.

Hi Dave
Thank You for the excellent post. Your Preference,..Why it is.. and it's application..
I have air lockers on the old Troopy. When engaged, Every wheel bites and has been an obvious asset when needed. The LSD in the front to me is still only one wheel biting at a time whereas the diff lock will have Both wheels biting and pulling. Yet it appears from your example both (LSD and Lockers) performed well in Each vehicle under the same conditions. Food for thought. At this stage, unless I learn something different I am inclined towards the Diff Lock. The Spartan I will research..Sincerely, Thank You again.

Does anyone know about the Detroit True track locker?? (The only other one on my list) That is - Experience with it??
Before I embark on a front 35mm spline upgrade It will obviously be best to do both at the same time.
Regards
Bony
