6x6 l/r

[Olive Drab]

the place where I did my apprenticeship had a contract making diffs for the army. I think they were for the 6x6 just because of the timing. my question is Have any ex-mil 6x6 been sold off to the general public or do we expect to ever see any for sale?

I've go this wierd idea of a l/r halftrack going on in my head. These would be a good starting point maybe.

[Sprint]

theres a photo of one being used as a tradies truck, so at least one escaped!

[101RRS]

there were 6x6's that were not army.

[101 Ron]

Some were sold off including a LRPV, but the vehicles were near total write offs.
The last I heard the army was under instruction to repair damaged vehicles at all cost as replacement was unlikely.
If the Mercedes 6x6 replacement vehicle program goes ahead this should change.

[Lotz-A-Landies]

Just to hyjack the thread, Did the 6X6 get the Oerlikon diffs or which ones had them?

[Bushie]

there were 6x6's that were not army.

And here's some of them

A few military 6x6's have escaped many years ago, as with 4x4's, but there has been none replaced for some time.

They are slated to be replaced by merc g wagens in 4x4 and 6x6 (I have a brochure somewhere) so we should start seeing more in the next few years.

[LR V8]

Here's an interesting article. About the new LRPV, but goes onto talk about the medium/heavy vehicles as well:

The Australian (http://www.theaustralian.news.com.au/story/0,25197,24415712-31477,00.html)

I love this quote:

" It is expected that some of the decommissioned four-wheel-drive vehicles will be disposed of as army surplus. "

:)

[mcrover]

There are a few non military ones around but if your talking half track you dont need 6wd as the track is a continuous loop it only needs drive from 1 end.

Excavators, Dozers etc normally have drive at the rear of the track and a series of Idlers.

This also gives you a pivot point so it can travel over obsticals articulating rather than putting all the twist into the chassis.

But if you did want 6wd, this is what you need

This is how it fits together

And this is what it can do when you done

Just a question, was there (are there) any Fwd control land rover 6wds ?

Why not just take the drive from the rear PTO point on the transfer case?

I suppose they didnt want to have a second shaft running like the army ones are, I dont know but I think that is a nice neat set up.

If you wanted to run a PTO winch I think the PTO rear wheel drive might be a problem as well :)

[Lotz-A-Landies]

I think the loss of the PTO is a problem and with the drive to the rear axle going over the top of the middle diff banjo there would need to be a lot of clearance above the diff.

I prefer the design of the drive done by Custom Conversions with a chassis mounted box moving the drive over to the LHS and having the rear diff offset to the left. (The next two piccy were taken in the carpark of the truck stop in Yass.)

Using a double cardan joint over the middle axle housing, like on the Perenties.

It was done that way for many reasons.
The later model landrover transfercases are not designed for a extra axle drive.
Note the 101 / early range rover transfercase was designed for 6x6 operated as the 101 was designed for operation of a power driven trailer.
This is the same transfer case used by the the Prentie and county 6x6 rovers.
The fabrication and fitting of the Morse chain drive and dog clutch is easy compared to other options as per the above photos.
Note the Australian army International 6x6 trucks had no problems using a similar set up and it saves the use of a pillow block bearing and many extra tail shaft uni joints went using a twin tail shaft set up.
A twin tail shaft set up tends to have the tail shafts alot lower to the ground and easier to be damaged.
Twin tail shaft drives tend to limit wheel travel with the tail shafts running out of spline travel too.
A few F/C 6x6 landrovers were made by landrover approved specialist companies as prototypes only.
I have shown these photos before, they are from my 6x6 WW2 studebaker.
Note the extra complication of running extra axle drive and how quickly the wheel travel can be used up in a 6x6 set up off road.

The series three f/c was made as a 6x6 and a few 101 military units were converted and called a 127 fc........very small numbers

Dont know what system they use, Im assuming most of them would just use PTO but I found these pics.

I recon this would be your best starting point for a half track.......or not :p

101 bloodbox with rear chassis extension and body bits off another 101 ambo by the looks of it.

In fact not all the 6 wheel Land Rovers built in the UK have 6 X 6 some are only 6 X 4 driving the front and middle axles the rear is lazy just like the Holden and Ford 1 tonners with 6 wheels.

[Phoenix]

there are videos of that 101 on youtube in a few places. It is quite a monster. the top one is interesting, but that is the only photo i've ever seen of on.

I do believe that some FC 6x6 prototypes were built.

[Olive Drab]

thanks all, that red one looks way cool. Add that to the list of " i'd love one"
Does it constantly drive both diffs when on road?

I am interested in converting 6WD where do I find this gizmo fitted to the rear diff in this picture? Can you give me an address?

Why not just take the drive from the rear PTO point on the transfer case?

GarryBecause it doesn't replicate the Hi-Lo ratio without a second gearbox.

Yes we know the Perentie 6X6 does it - but it has a two ratio output.

[Lotz-A-Landies]

Does it constantly drive both diffs when on road?A lot of these 6X6 Defenders were built as special contracts for various organisations in the UK.

https://www.aulro.com/afvb/

There are also a lot particularly the TACR2 (Range Rover) which are 6X4. As for the 6X6 a lot are C6X4 with a lazy rear axle and 6X6 automatically selected when the centre diff lock is engaged.

As for a Land Rover half track - Land Rover already made one based on the Stage 1: the "Centaur".

I believe Foleys in the UK at the very least use them if not make them. Can find them fairly easy on google if you search for foley 6x6. I contacted them by email at one stage but never got a reply

I think Ashcroft transmission do those drop boxes too.I think you'd be looking at 4-5000 uk pounds though.
I made 2 of my own,1 for each diff, back in the 70s by fabricating the gear case from steel and using 2 high range gears plus the helical half of the intermediate gear from series 1,2 or 3 Landy transfercase.Extensive experience revealed that you can getaway with a 4 pinion pegged Rover type diff for the middle axle providing you build a highly articulate load sharing rear suspension, but a Salisbury should be used for the rearmost axle. I never broke a middle but broke about half a dozen rears during that vehicles life of very severe cross country operation.
BTW, the LandRover Centuar halftrack that used track components from the Alvis Scorpion light tank was unsuccessful for a number of mechanical reasons.
Diane(Lots a Landys) "Ugly as Hell'' camper is next to useless offroad due to being fitted with a non load sharing, non articulating leaf spring bogie.There's a Google video somewhere of it making areal meal of climbing over a fairly small sand dune.

Wagoo.

Wagoo.I have to agree with that - it's not a model that interests me either, would have the turning circle of an aircraft carrier! :o

I'm not sure which "Ugly as hell" camper you are talking about! If the yellow 101+a lot more - it's a nightmare - the two rear axles are too far apart and in Australia would be illegal to have non-load sharing axles more than 1 metre apart (unless each axle is capable to taking it's own weight and the total weight of the adjacent axle).

If you were talking about the red Defender style camper with the leprechaun sized door in the side, that one is coil sprung but as we know coils don't load share.

Diana

BTW: remember where you mentioned that Gog's (SADF SIIB ) nose drooped and you thought the chassis bent? I have found the problem, normally the SIIB have a full "C" section upper frame that runs from the front bumper to on top of the rear chassis cross member. This upper frame is supported on about a dozen inverted stirrups welded to the main chassis along it's entire length. In some models of SIIB the upper frame is cut off at the gearbox, usually on the third of these stirrups behind the axle centre. Gog has been cut off at the first stirrup immediately behind the axle centre line. When the screen was removed the single stirrup was unable to support the cantilevered weight of the nose forward of the dumb irons, hence the square top of the stirrup bent up into a pyramid shape. We will be restoring appropriate support to the upper frame in the near future.

[wagoo]

Yes Diana I was referring to the spread axle 101.Sorry I should have wrote Microvas ''ugly as hell" camper, as it first appeared on his post. Have you seen the Google video I was referring to? I linked to it on another thread around here somewhere a few weeks back.
Coils can be made to load share if the upper ends are seated on the extremities of a centrally pivoted see saw, one each side. Saw it on an old Soviet Bloc truck in North Vietnam.
Interesting about the 2b subframes. I never really thought they would add much rigidity to the chassis, but just assumed they gave a straight flat platform to simplify mounting of different rear bodies.
Wagoo.

Note the extra complication of running extra axle drive and how quickly the wheel travel can be used up in a 6x6 set up off road.

Departure angle gets used up quick too and is nothing like the measured angle on level ground. So keep rear overhang to a minimum.

Wagoo.I think what is the actual problem is that the entire cab assembly is mounted to the upper frame, which protrudes from the front of the main chassis by about 600mm. The stirrups both support the upper frame to a vertical position above the main chassis and stabilise it fore and aft. Remember the firewall is mounted vertically above the front dumb irons forward of the foremost stirrup.

When you remove all but 4 stirrups (2 on each side) to this upper frame the weight of the now cantilevered cab wants to rotate around the prop which is only bolted to the front dumb iron. It seems that the only thing that currently holds the assembly up is the windscreen frame.

When you remove the windscreen frame the cab hinges down by deforming the stirrups. :(

https://www.aulro.com/afvb/images/imported/2012/12/269.jpg I can put a few pictures of the underside of this if you would like an idea of how it goes together. Apart from the 2nd axle there is also a PTO to drive the front winch.

Hi LieutenantRover,

Did you buy this rig from a dealer in Bayswater about 15 years ago? I remember having a look at it in a yard on the corner of Garret Road and Guilford Road. Very well put together rig from memory. Where have you been in it?

Regards Warrick.

[LieutenantRover]

Its been sitting in my shed for about 6 years. It needed a lot of work done which I have now almost completed. I should be hitting the road in the next couple of months and plan a trip to Cape York once i've given it a couple of test runs locally and to Cape Le Grand.
