Ikea 6X6D - anyone have an allen key?

On Australia Day we met a fellow looking for input to the design of the replacement for the Defender, this fellow had worked for Land Rover for several decades, so I asked about my Defender 6X6 and today an answer has returned.

As I suspected the vehicle was an approved conversion on a 110 chassis, an incomplete 110 was sent to Reynolds Boughton (originally the Scottorn Trailer factory) and was then converted to 6X6, after that the cab chassis was sent for fitting of the cherry picker. After both conversion completed and tower body fitted, the vehicle returned to Land Rover Special Vehicles for finishing and dispatch to the customer.

So my vehicle is confirmed as Land Rover Special Vehicles with the through drive by Reynolds Boughton.

The concern is that Land Rover still own one of the same conversions used on the Land Rover Experience track, but owing to problems of lack of spares for the middle axle it is now 6X4. :(

Looks like I am going to look to having a "Plan B" commenced almost as soon as the vehicle is back on the road. This will definately be on a Salisbury assembly!

A very sensible idea... Personally I would give Bill enough folding stuff to make it worth his while, the run of a nice lathe somewhere, and a couple of blokes to do the heavy lifting for him (to save his back/arthritis).

I'm afraid my heyday is in the past Ben. It takes me a week now to accomplish what I used to do in a day. As I mentioned somewhere else, most of my mates or contacts where I used to get splining, brooching or jig boring done have either passed away, retired or just become too expensive. In the old days I could even get Hollingers to do stuff at affordable rates.
It just occurred to me Diana ,that Reynolds Boughton are not likely to build something weaker than the Rover diff. So do you know what part of the thrudrive assenbly is prone to failure? Could it be the LandRover parts that actually failed? In which case an Ashcroft CW+P and 4 pinion carrier may be a solution. If the actual thrudrive is the weak link it may only be something like the power divider differential that possibly could be deleted in favor of a simple dog clutch drive disconnect. I think power divider gear breakage would be unlikely unless RB used silly udersized gears.

Have recently been doing a little more research. The through-drive system used in my 6X6 defender is the same system as in the Scottorn 6X6 Range Rovers, although my rear axle is a Salisbury unit.

Here is the brochure for the Scottorn RR 6X6 http://www.lr-mad.co.uk/dwnld/Scottorn_6x6_brochure.pdf

The new cab and chassis were mated for the first time this afternoon. Everything is going O.K. The OEM brackets are fitting where they are supposed to fit. Now have to box around the OEM reinforced chassis rails. Next week the tray should be offered up and the brackets modified or moved.

Then the chassis can go off to paint.

During the past week I have been having correspondence with Reno at Accu air in the US about an air suspension controller for Ikea. The advice has come back against a 3 axle controller and to treat the rear axles as a 2 individual corners, otherwise the two axles would be fighting each other. Further they agreed with my idea of running each side of the two rear axles in parrallel with a single sensor on the 3rd axle. While I thought it only necessary to run parrallel off road they Reno says on road too. The only difference was the idea to switch off the e-control of the axles off road so that oposite articulation of the two rear axles wouldn't be compounded by the EAS attempting to correct the situation.

Yes but Reno is a salesman, who one must obey, you on the other hand are just some fancy sort of plumber! :o ;)

Addit: Wasting work time ATM. Was just re-reading the brochure (link above) on the Scottorn RRc 6X6 and spied for the first time the specification of the through drive. (Too much looking at pictures!)
"Second Axle: "Scottorn" through-drive silent chain, spiral bevel. Lockable differential engaged/disengaged and differential locked by vacuum from gearbox mounted switch..."
A lot of the aspects like the vacuum operated switch on the gearbox is the same and presumably the ratio. What it confirms is the drive to the middle axle is via a morse chain not a gear set. It also means that modifying a Salisbury for the same design is quite possible, removing the vulnerable Rover diff from the system.
What I don't know is if the Rover diff is also lockable.

Todays effort.

The tray is 2200mm inside the combing.

Just to confirm it's not off some foreign jobbie!

The tray originally came from a single cab Defender 110, so all the mountings underneath, mudguards, tool-boxes all had to come off. Then it was a matter of making up new mounts so we re-used the mounts from the tower body leaving the centre clear for a later addition of a trundle tray or just tent pole tubes etc.

The photos are actually taken as soon as the tray was lowered, it has been fixed about 30mm higher in the same height the tray was fitted to the 110. There is only about 300mm overhang at the rear, less than half the overhang on the 110.

Hi Diana

Are you using the 6x6 for any particular task or building it up as a collectors vehicle, (i can relate to both haha), 6x6 has always intrigued me, hopeful one day i'll buld one of my own, maybe on my new D2 haha. Nice build by the way, your cars are all very interesting

Cheers
Will

Hi Will

I'm building it back up because it was wasting away dissassembled under tarps at a mates place. It's a factory conversion, partially built in the Solihull factory, sent to Reynolds Boughton for conversion then returned to the Land Rover Special vehicles factory for completion and delivery to the customer.

The factory coil spring vehicles are so rare in this country that it needs to be working, even though I'm taking it to Land Rover Au Isuzu specs, because petrol is a thing of the past and 2.5 litres isn't enough for a vehicle with a GCM of 7.5Tonnes.

I'll use it for general running around, and a little touring and I'm hoping it significantly out performs a 130 in those roles. It will have the ramp over angle of a 110 and the space and load capacity exceeding that of a 130. But the turning circle of a 130.
