IMO an unlocked portalled RR with 35's would go further than a locked standard RR with the same tyres here in Vic.

We dont necessarily have to have clean terrain. The courses just have to be set so that diff clearance isnt as much of an issue and i think this will happen. There is nothing more boaring to watch than a rig scrable around getting diffed out all the time. I think our rockcrawling comps will head the same way as the US. Less diffing out rocks and more big obstacles (like big ledges and climbs)

Yep i agree!

which is good because it allows people with only 36's and 37's to enter...cog becomes more important than tyre size and driver skill should determine winners.

just back to the volvo portals, does there seem to be a weak point in the design??
i have seen them apart and the axles and gears look strong compared to rover gear, especiallly with the hub gearing.
is the r+p weak, is it similar to toy/rover or anything?
the housing if anything looks to be a weak point, but only maybe with a three link. but then they came of trucks that carry weight.
i only know of one guy using them under a 110 but thats only just started to wheel.
i do agree portals would be good in vic. IF you keep a low c.o.g.
maybe that 110 will be at the wandin day.

I think the volvos are a very balanced design although not as strong as a mog or build D60. The only weak point I have heard of is the diff lock and guys put modified detroits in to cure. Dont know whats wrong with the diff lock though - this is just what I have picked up on pirate.

now i remember an article about converting the vacum locks to a cable locker for reliability and a more positive mesh.
thanks sam

I have spoken to a fella from Mlitary Srplus Aus, yes he has them ,, no he cant release them. So how can I get some............. come on fellas someone out there has to have this info.... SOMEONE.... WHERE ARE YOU????....

Volvo portals are a dead axle the only parts availabe are excess stock so to speak.. once it's gone thats it (so the army say). I don't think they are an option because you can build a stronger diff using landy parts... Yeah the portals are good however in the states no one has won major event on them so it leaves one thinking.yeah...

Mal Storey I believe and I think he is in Brisbane somewhere

Posted: **Mon Feb 09, 2004 8:37 am**

Mal's portal boxes are 1.3:1 and not chain driven. His have two intermediary cogwheels, so rotation is kept the same, just as a chain would do.

They are bolt on on Rover and Sals axles, though.

definitely timmy :cool:

but he's such a maller

i agree that the housing may be the weak spot. the square tube is good for carrying loads but i think with a lot of torque and stress it would rip. my diffs are set up like tim's - standard rangie rear end, and 3 link + panhard front. the welds were peened which would reduce warpage but i don't know whether that will stop brackets from being ripped off the housing.

some locker failures can be attributed to the volvo vaccuum diaphram - which is badly designed junk. i expect to have to problems as i will be using the two-way rangie diaphrams.

More info onmaxidrive portals.

If the maxidrive portal box's are essentially bolt on - does that mean that hypothetically you could run hilux centres with McNamara axles with the portals bolted to the end?

Hmmmm......

Posted: **Fri Feb 13, 2004 8:33 am**

If you have a rover style mounting flange and order custom length JacMac's I think you can run whatever you want in the center.

Yes

Posted: **Fri Feb 13, 2004 10:28 am**

that is so sweet :cool:

good thing it's only 1.3:1 ratio too. otherwise you'd need to find a centre with a numerically low ratio to get any decent road speed.

but a 30% increase plus a 5" lift should be pretty spot on for going to 40" rubber.

Posted: **Fri Feb 13, 2004 11:28 am**

IMO this would be a really good axle to run, although somewhat expensive. Very lightweight compared to the other portal options and parts are not a problem.

Posted: **Fri Feb 13, 2004 11:29 am**

NAM - perhaps you should get rid of those Volvos, they are so last year. MD portals are where its at!

Posted: **Fri Feb 13, 2004 12:33 pm**

I love the clearance I get from my 406 unimog axles. Sorry I realize this is a Landrover forum. cheers

I hate to say it about a toy :oops:

, but it looks like a nice rig with the mogs!!!

Thanks . Heres a picture from the front.

How much do these MD portals run for???

Let´s see Options:

A. MD Portals and Lockers (your choice)

B. HHD Axles, CVs, R&P, Lockers...etc...THAT WILL BREAK and be $$$

Is there MUCh difference???

I mean, would it not be smarter to stick with stock 24 spline axles (cheap as hell at the junk-yard) and stock CVs and 3.54s and slap in the portals????

I have a smile on my face!

Got to go to a meeting...

Nadim :armsup:

Posted: **Fri Feb 13, 2004 7:53 pm**

MD portals were around 2.5K per corner.

When did you get this Price Quoted?

Posted: **Fri Feb 13, 2004 8:30 pm**

long time back.

do you have a current price.

would be divorce material if I order a set. lol

Im pretty sure he is talking 8grand an end now.

Posted: **Sat Feb 14, 2004 12:27 am**

Just called OUTBACK IMPORT in France (I am in Germany at the moment) and it seemed that they are selling the LOT of 4 portal MD drop boxes for a WHOPPING 16,500€ (do NOT do the conversion, you´ll faint!)

SO...
It seems that I´ll be sticking with the tried, trusted and HOPEFULLY WILL NOT FAIL MD shafts and other mscelaneous things...

He told me 12grand total the other day for the 2 axles. Although not sure if that was installed or just a kit.
