DII rear Suspension

Postby sledgehammer » Tue 26 Sep 2017 9:36 pm

I'm putting the disco back on air
what brand of airbag do you recomend? Contitech OE (made in germany) or Dunlop the pictures i saw on a supplers web site said Dunlop but had a diffrent logo super imposed over the image i dont want to end up spending my hard earned and ending up with a pile of [rusty outrigger]
same goes with the hight sensors Bearmach or Allmakes any recomendations
what else will i need to put it back on air clips for the top of the bags pipe and push fit connectors as some mongral cut the pipes short when they put it on springs

cheers

hi all
i got the OE Contitech airbags, landrover hight sensors and britpart bumpstops (i thought these would be good enough as there not a wearable part and not safety item)
i striped out the springs reinstalled the air pipes (recovered from a scrap dII)
drilled out the required holes as it has a galv half chassis installed (galv sometimes filles the holes)
i went to fit the air springs and they don't seat properly at the top the retaining lugs dont protude through the top spring mount enough to get the retaining clips on
any ideas?

How much too short are they, is it just a galv / paint issue?

hi charlie
its a manufacturing thing ok the holes will need a slight clean out with a drill but the real problem is a "return" in the center of the pressing if there where coil springs this would fit on the inside helping to seat the spring in position but for air spring this return is too large and holds the top of the airbag away from seating on the top spring mount
i have measured a air spring chassis and need to cut this return back to 1cm measured from a straight edge placed on the top of the mount
ok im probably not explaining it well i will try to take before and after pictures
to do this job i have had to purchase a air cut off tool and a air die grinder

If it's going back on air I would have thought the seats were correct for airbags anyway. I must admit I didn't know the seats were different.

some pictures to try explain my problem
https://www.dropbox.com/s/esybjyds24muq ... 2.JPG?dl=0
after cutting (it took about 1Hr of cutting using a air powered cut off grinder for each side)
https://www.dropbox.com/s/37mxdqdggpshx ... 5.JPG?dl=0
the lenght of that return stoped the airbag sitting on the upper mount so i trimmed it back it now locates properly
i hope that explains it a bit better

I does, didn't realise they were new mounts. Something to look out for in future.

Thanks for the pics.

This problem arose due to the vehicle having a rear 1/2 chassis replacement
all is well with that now and it's on the road
there is a slight vibration whilst driving i have checked the front prop joints and its not that my suspission is its oil in the invector wiring loom as i had a error logged of inj 3 open circuit so i will disconnect it clean it if the problem goes i will then buy the replacement modified injector wiring loom for it

a big thanks to ishman for the loan of his nanocom

Not relevant to you any more but I bought Dunlop's for mine and was told they where OE ?
Happy with them, so not an issue, just curious.

Hi TS
it wasn't a issue with the airbags it's to do with the manufacture of the replacement rear half chassis (the upper spring mounts are a aprt of the replacement chassis section)
on another note
i dissasembled cleaned and reassembled the injection wiring loom and all is well again
