404 DISC CONVERSION

[landcruiserhj60]

I have just put my pinion conversion kits onto the 404 axles. Removed all the hubs bar one which is well stuck I emailed killeraxles.com after reading this thread.

http://www.pirate4x4.com/forum/archive/index.php/t-168674.html

got an email back:

I said:

Would yo be able to quote me for 2 x disc conversion kits (one for each axle)? What
calipers and discs are used with this conversion kit?


The price for the disc conversion is 1250 Euro plus tax per axle.
We use Dodge rotors and Toyota or Chevrolet Corvette calipers.

Wolfgang

Is it me or is this steep........................these days thats as good as £2500 for bot axles. I can buy a complete 404 for under £2k

This leads me onto the question. Does anyone know if there are any kits out there? Uk preferably. The EURO currency situation does not help at the moment! I have asked for the price for just the 8 lug hubs. May be able to make my own calper mounts. Christ those hubs are on tight!

IIRC range rover disks and calipers can be made to fit???

[dxmedia]

Oh ref the hubs, I bought a hub puller off a fellow 404 owner some time ago just in case I needed to do mine... After reading Jims (shaggy) escapades (foodfight.org) and bending of steel, a proper puller is needed.

[landcruiserhj60]

I am sure the whole brake thing is possible without spending 2.5k on the axles. I am in the process of removing the hub at the moment mm by mm in between adjusting the puller hammering the hub and going on the computer. Like the idea of the 8 stud hummer wheels though! The discs need to be beefy just to be able to fit over the hub. This situation trying to find affordable disc conversions has got me thinking about having them manufactured to sell..................................along with the pinion kits

[dxmedia]

What about a pair of SBU axles which are already disk?

[landcruiserhj60]

I am kind of comitted to the 404 axles as I have two pairs now. Beautifully put togeather as with most of the proper mercedes vehicles. I have thought about a prop shaft disc as I am never going to be going on road or at any speed. It seems there is little in the uk with regard to disc conversions. I have a good engineering firm 2 units down from me. It is simple technology I see no reason for it to cost so much money.

Hi did you get the 404 chassis and axles from Nathan? Is your project going to be a road legal buggy or purely off road?

I sympathise about the cost (I personally would go for Disc axles but I do see your point about already having 2 sets of good drum ones) I once bought a Disc brake conversion kit for a Series 2 Drum Braked Landrover, sadly it went with the Landrover when I sold it. (maybe I could have lent it to you to offer up and see what would need to be altered for a Mog.) (It was they same kit they sell to Jaguar enthusiasts to convert the XK120) The kit was £500 per axle, but as I said it was a kit that was already produced that needed minimum alteration for the Landrover. It might just bolt straight onto a Mog but if it does, go right out and buy a lottery ticket!!!! The Hight cost, is to claw back the time an engineer takes to adapt/build the prototypes and then spent time testing for safety/does it actually work?, might be a couple of years all told, all of that has to be factored in once you bring in a business aspect. We personally, bolt on something here, shave off a piece of metal there offer it up, does it work...yep it works for us OK....but if we sold it to the guy who drives over the Alps, will shaving off that little piece of metal cause the thing to overheat and boil away the brake fluid??? that,s what costs.

[landcruiserhj60]

Yes I did end up buying the rolling chassis from Nathan. Engine and box out of it is on theifbay at the moment (trying to claw a bit of money back) Going to chop the front of the chassis so the aproach angle is 90 degrees. I picked another set of 404s last week, don't know why but they were £450 so I thought it would be rude not to. Just waiting for the guy to take them off the mog rolling chassis. Fingers crossed should have the GMC lump soon enough. found a novel way to get rid of the chassis taking up so much space. I have found quite a bit of info on Pirate:

All the serious mog stuff seems to be going on in the US.

The cheapest option for me is going to be to turn the hubs I have down and get the local engineering company to weld the laser cut 8 lug flange on.

Looks to me like you weld the caliper mounts to the drop box?

[landcruiserhj60]

o RE road legal. Would love to but have not decided yet. God knows what that thing would be reving at lol

[minimog]

thers quite a few ways to do the disc conversions but it all depends on what wheels your planning on using
ive seen a very good conversion using g waggon brakes the down side is your stuck to g wagon wheels
the portal rover using lr parts still use the mog wheel and is probs the easyest way of doing it but is far from the best way
ive seen a yota set up used and might be the best way because the pcd will fit on the wheel flange and the discs fit over the studs(unlike the landy one which bolt behind and would you like to pull the hubs every time you need a disc)
the yanks tend to do the 8 lug hubs using corvette calipers but if your in the uk not the best place to sorce parts (hummer wheels yer just nip the the local vauxhall dealer)
if it was me turn the hubs down then change the stud paturn to the most popular 4x4 then use them parts that way down the line the parts will be cheep and easy to get

[minimog]

as for backspacing if you go for 17"+ size rims you wont have the prob of the rim fouling the portal box

[parrotveasey81]

silverline4x4.com are now doing 17" steel wheels
17"x8" et00
17"x9" et-32
if thats any help

[normalbloke]

17"?

Bless:)

Hi Jonathan,

Our 404 disk brake kit converts the "NATO" wheel pattern (6 on 205mm) to the
North American 1 ton standard (8 on 6.5 inches). It will make your axles
7.5 inches wider. 16.5 inch diameter rims for an H1 Hummer or 17 inch rims
for an H2 Hummer fit nicely over the brake system and provide a decent
backspacing.

The brake system uses a complete Ford Heavy Duty F250 setup. All of these
components were designed to work to work with each other. Our kit provides
the greatest stopping power and GVW capability available for Unimog 404
axles. All of our custom made components are plated to withstand corrosion
and have unparalleled durability and maintainability. All of our fasteners
are graded and most of them are plated.

I have attached a copy of the installation instructions for your
information.

The cost of kits is CAD 1125.00 per axle. This does not include friction
parts. You will need rotors, callipers, calliper mounts and pads to
complete the installation. These parts are readily available in North
America. Your email address appears to be from the UK, so it may be
difficult or expensive to source these parts. We can provide them and often
do so when shipping to Europe, Australia and Africa. Friction parts are CAD
400 per axle, plus core charges of CAD 150.00.

The shipping weight of kits and friction parts for two axles is
approximately 350 lbs (160 kg). Rail and ocean freight shipping is most
cost effective way of moving these products, though we can ship using
whatever method you choose.

Please feel free to contact me if you have any questions. Our kits are top
quality, made in Canada from Canadian or US steel from our own design. We
stand behind every product we produce. We have sold hundreds of these kits
worldwide since 2002.

Thank you,
Mac

I have all the original brakes off that rolling chassis you got from Nathan

[landcruiserhj60]

lol, do you want to sell them?

[s.frimodt]

Here is some pics of the disc conversion using LR parts. Not ideal in my mind either, but an easy source of parts and simple to make.

I have bought 2 sets of hummer wheels alloys and steelys. Looks like I am going down the american laser cut brackets route, pictures to follow

[micky1]

modding a set of 404's for my landrover at the momment.

looking at disk conversions, and ultimately an axle tube swap to run lr diffs and a higher r&p to get the better gearing.

[agrover]

[wazza]

for anyone who's got or interested in the landrover disk conversion i would highly recomend you never go anywhere near it!!! i have it and can prove it!

s.frimodt - you need to weld hell out of your brackets in order to stop them moving at all, otherwise when braking hard you WILL distroy your drop boxes by initially tearing out the two bolts at the top of the box, the casting isnt strong enough to take the twisting force excerted on them.

ive bolstered mine up by welding a square plate inbetween them on the top of the box, it was advised by a bloke who destroyed all four boxes a couple of times over, befor he found that this worked.

ill be getting the jeep back from storage in the next week so will try and get you some pics, but ill be compleatly plateing the things up so there's no chance of it killing the drop boxes as i can't afford any more at the moment!

[minimog]

i to have seen them and yes the mounting is rubbish im to are going to go landrover disc route(the hub part is the simplist to do without pressing plates and welding to the original hub)
BUT not using the caliper mount ive seen a far better way that uses the shoe mounts and it looks a far better way
also the g wagon one is good but parts for the kit arnt cheep
ive also shortened the short side of the axle 4" so when the disc conversion goes on im only 2-3" wider than the standard set up
