Thread: defender 110 ute

Poor excuse .


Congratulations, they look cute when they're asleep .

Well finally took the defender for a test run at glasshouse click the links below for videos the suspension worked real well cant wait to get back out there enjoy

Hi everyone.

I have a 130 Defender Big Cab and use it to carry my dingo and tow my 1.5t excavator so I need a good suspension. I have bought a set of the Airbagman bellows style springs for the back of the ute but have had them for at least 12 months and still havent decided how to do the conversion. I have also bought a pair of ride height control valves from an Iveco and planned to install them on the rear to automatically adjust the springs with a compressor and air tank permanently monted in the car.

My biggest concern is whether I should leave the factory twin coils in place on the axle and install the airbags slightly inboard so I always have the assistance of the springs (to take load from the bags most of the time), or whether I should install the bags in the position of the springs and rely on them entirely. Dingo and other components carried in the tray regularly comes to 1.5tons but the ute is driven lightly loaded about 50% of the time.

I had a set of manually adjustaed bags in the back of my Disco2 for towing the trailer but the hassle of adjusting the pressure for a constantly changing load sent me nuts and just took too long. It has been suggested that I will be able to remove the rear sway bar for better wheel travle off road, but how do I set the height controllers to let the wheels travel freely when I want to and give tight control other times?????

Anyone have any thoughts or experience with active systems?

BTW, looking on the net at control systems in the states, there are some incredible digital controllers for the transport industry but the cost are just as incredible.

BTW2: If you are still contemplating the cab extension, mine was done professionally but is still a bit of a dogs breakfast and I think if you could see how it was done, you could do it neater if given the time. Seems that the coach builder only had a stick welder to do the sheetmetal. Let me know if you want to see pics as the roof lining is still out. They cut the roof about 100mm behind the windscreen,fitted a flat sheet and hand made the rediused edges

Thanks all.

...

Firestone are probably the largest manufacturer of air springs. Using their terminology, the 2 main styles are reversible sleeve style (like shown in posts above) and convoluted style (can be single, double, triple, etc. convoluted).

Both styles have bellows (the name given to the flexible rubber member that contains air under pressure to act as a spring and support the load.

The reversible sleeve style has a piston, which can be shaped to change the effective area (pressure required = load / eff area) over the travel range. These generally can have a greater range of travel compared to the convoluted style. The effective area of the convoluted type varies widely with height. Because of this the reversible sleeve style is better suited to 4x4 suspension. The convoluted type is ok for a helper spring.

Sorry I don't know anything about the Iveco ride height control valves.

I have the Airock system. It uses sensors connected to the suspension arms with adjustable links. In basic terms, the ride height of each air spring is calibrated by adjusting the height of each spring after the system is installed.

It has 3 modes: offroad, highway and freeway.

In offroad mode only, buttons can be used to change the height, pitch and sideways tilt. Above 32 km/h (20 mph) the height will return to normal height. These can't be changed in the other modes. It uses the speed sensor for active mode, which counteracts body roll when cornering or pitching during braking - active mode doesn't operate at lower speeds.

This assembly has the bellows Firestone part 1T14C-8 with the longest travel you can have - approx 14" travel.

But the piston is a poor shape for what we want. The best piston (for our purposes) to use with the above bellows is Firestone part 9778/NAD-18053.

The following pic shows a 1T14C-7 bellows assembled with the 9778/NAD-18053 piston (airspring assembly W01-358-5426) - see truckspring.com page US$147.86 This bellows has a slightly shorter stroke.

The max/min heights are shown on the pics. Operating heights should be restrained to a little less than the max and a little more than the min.

I have bought stuff from truckspring.com and they were delivered promptly.

Finally got around to ordering some!

However they don't seem to stock the bellows on their own as replacements. Any idea where I can get them, or am I crap at searching?

Gday rar110 I have a range rover classic front diff on my defender which would allow me to run air bags upfront but I wont at this stage as it can be unstable unless you have a controller that can adjust the springs very quickly air bag man raved on about how I can have a solenoid valve fitted which i could switch on to allow the air to flow from one side to the other GREAT when you are on a level track that has deep washouts etc but when a side slope comes along the load changes and the air is forced into the wrong side which can cause rollovers, one day when I have a bit more cash i might build my own controller (I'm in the automation industry)


Isuzurover dont know if you are still keen on the idea but here is some info of original air spring replacement for 110/130





the brackets above the spring are 63mm

Hally - congrats on the new arrival - who is probably quite large by now???

I need to make some brackets - any chance you can measure yours up for me so I can get them lasercut while I am waiting for the airbags to arrive?

Time for some stupid questions...

The centre bolt clamps the bellows to the piston, correct?

All the conversions on here seem to have a female thread and a shcs to clamp the bellows to the piston. My air springs (W01-358-5426) have a bolt protruding from the piston. I assume I can cut the bolt off flush with the baseplate?

im thinking from memory that you can cut it off flush but dont take my word for it i have not done one for a long time
