Hi Anthony,

Mark is the big ugly dude, You won't find him here..........and the answers are "yes" then "almost". We've got a bit of testing first before Mark starts any marketing.

Regards. John.

A couple of pics from last week of the diff centre going in.

End play on the pinion set.

There is a bit of work to do though as the axles have to slide out first.

Hi All

Nice to see an open axle:ylsmoke:.

Do you guys know the splines count and shafts diameter on front and rear axles of this Isuzu or Mitsubishi light trucks?

Cv joint outer diameter?

So far i could find, teh ring gear is about 300mm diameter, much bigger than dana 60 axles.

Regards

I am really curious about the strength of this axles:ylsmoke:

I am really curious about the strength of this axles

i second that. still wondering whether it might be an issue for me, but the old fella rekons the Transfer-case or gearbox would go before the axles...

 

[engineer]

I've never seen one broken...Transfer is the weak spot, but even then.... I've only ever seen clutches fail (pressure plate), Transfers just start making heaps of noise.

From what i have seen in china, this size of small light truck come with very similar diffs and axles.

Shafts are usually 36 to 40mm for the rear and 33 to max 36 for the front.

I know some company make some with double U joints but so far i did not find them, only single u joints.

I am looking for this axles for some special built with big tires, but so far they are all with narrow read width for twin tires.

Might be possible to cut them off and extend them, but i need longer shaft so i need to find a company for that.:chef:.

I found a small one who can make what ever i want but based on carriere that take 275 mm ring, 38mm shafts and traditionnal design i would say, as toyota. No front opening as on GM14 bolts or isuzu, that's a shame because it offer goor opportunities for boltign a transfet PTO for driving an second rear axle:ylsmoke::bike_rider:

Could be quite easy to make difflocks on those actually, similar to mercedes axles, just need a proper welding on the diff carrierer with a claw sleeve, plenty of room for that:ylsmoke:

not to hijack the ATW thread, but I may be able to shed some light on the axle issues being discussed here.

A Dana 60 has come in many versions over its long life, you can read all about it here:

http://www.pirate4x4.com/tech/billavista/60_front/index.html

Its a light duty truck axle that is only rated about 5500 pounds in a steering application, though there are exceptions like Super 60s in a Kodiak 4WD or a fully custom front end from Dynatrac or Spider, etc.

An FG truck has a factory GAWR of about 10,000 pounds on the rear axle. This is comparable to a Dana 70 or an AAM10.5, which are both rated around 10,000 pounds and have ring gears in the 10.5" range (265mm). A Dana 60 will be fine in the front of a FG if built with good parts and king pin knuckles (not ball joints). You could expect a 6500 pound GAWR. Axle shafts and lockers are available upto 40 spline (1.7 inches/43mm) for Dana 60 axles as well as 300M axle shafts in 35 spline with CTM u-joints or an RCV u-joint, you would have some trouble breaking front axle components. A Dana 60 can be built to be VERY strong. An open knuckle design is more popular in the US on 1 ton - 2 ton trucks with closed knuckle/CV style housings being reserved for smaller trucks like Landcruisers and Land Rovers. These axles do not compare to a Dana 60 or Dana 70 in strength.

Using Dana, Sterling or AAM axles in the US makes a lot more sense to me, as there are tons of choices for things like brake upgrades, gear ratios, hubs, lockers, high/low pinion, link/tab and spring mounts, etc... None of this is available in the US for Isuzu or Fuso axles. Im not sure why you would want a double u-joint in an axle, though they are available for driveshafts and are typically referred to a double cardan joints. High Angle Driveline can build these for your application.

Popular with the off roading and rock crawling crowds for years, these axles (D60/D70) are almost unbreakable in a FG type truck, even with large tires. Rockcrawling with huge tires and high HP is much harsher than you would ever be in an RV/Camper/Expo rig. I would not consider custom axles for a larger wheel and tire unless the truck is going to be very heavy or the tires are going to be huge. You would be amazed at what a well built Dana 60 or 70 will hold up to.

Cheers

Hi Very interesting thanks:ylsmoke:.

I do know this dana are good, i also like the GM14 botls, but this axles are almost none existing in europe and asia or north africa, and that is where i am:bike_rider:.

I have no idea about australia but i doubt they would be very common down there too.

Isuzu on the other end is all over the place, seals and bearing available almost anywhere.

The rear diff carrier i saw could take shafts up to 45mm, side gears of course need to be matching this but it is possible. Probably un necessary as over 38mm it is really getting tough already.

And what i really like is the possibility to bolt a box in front of the 3rd member, 6x6, 8x8:wings: all doorsa re opened :sombrero: .

Anyway, if you have any idea of shaft diameter and splines count:chef:, please let me know.

Now i look forward to see this new truck and torsen diff on wheels, i used to own a double torsen landcruiser, it was unstopable in sand and mud, always crawling out no mater how bad it looked and cornering was never an issue as well as climbing side slopes on slippery surface, used to do a lot of hard stuf with that toy.:smiley_drive:

John,

How's the testing going on the parabolic suspension on the NPS? Any thing to tell?

Pics please :drool:!

Cheers

Hi David,

Nothing new really. All I can say is the 3 prototype NPS trucks we set up worked very well. We made some very slight changes to the prototypes and production has been underway for a few weeks. We expect to be doing alot of these conversions and are getting them made in large batches for the NPS and FG. Don't ask me when though (Mark at work handles all the accessory sales and marketing). One of the trucks was a camper around 5.4 ton and we set it up with 4 leafs at the front and 4 plus a parabolic overrider at the rear........it was simply too stiff.....beautiful on the highway but not good on the dirt. Dropped it back to 3 front and 3 plus overrider rear and it was perfect. The best thing about them seems to be their ability to allow the axle to move very rapidly while still maintaining load carry ability. So now corrugations should be a dream by comparison to OEM. For pics, The camper on 37 of this thread was one of the first ones.


We are pretty confident we'll be able to fit parabolics to the earlier NPS as well.

As a matter of interest, I have just started the R&D on a Torsen front diff for the current model NPS. It should be 5 or 6 months away having just done the first FG diff and knowing what we do now . The first batch of the new FG Torsen diffs have been ready for ages but we've only just got around to shipping them and they should be available in about 5 weeks. We're giving them a lifetime garauntee too.

Regards John.

what's roll like with the increased height/travel?

 

[Overland Hadley]

We have a really tough new motorhome model coming out in a couple of months...

When do we get some teaser shots of this?

Overland Hadley

When do we get some teaser shots of this?

Hey Nathanael,

Man, we haven't spoken for a long time....... always see you posting though. Hope you are well.

I'll let you know. One thing .......ExPo will be the first to know.

what's roll like with the increased height/travel?

Hi Julian,

Roll will depend on shock absorber settings. They are only about 40mm higher so they aren't really effected so much by height.
I haven't driven a Fuso on parabolics yet but will later this week. I've been off work crook but heading back tomorrow. We just put them on one of our Fuso mine buses weighing around 4600kg. This vehicle will have a higher CoG than a typical camper and won't have that in-cab ride control we offer so it should give a good indication of roll.

Regards John.

Interesting job that just went through the workshop if anyone wants to see some pics.

Handed it over to the new owners, Santos yesterday. It will be used for the transportation of pipeline construction staff and then double for VIP / CEO tours along the jobsite. So they intend to throw a BBQ in the back and use the 100litre fridge, etc for catering and the interior is virtually like a passenger aircraft fitout.
