Happy new year all


Not entirely sure if I'm being a bit dim here, but here goes....


I have a EAS leak in the front drivers side – the collet won't seal properly. I've re-piped the bag to the valve block to no avail. The leak is intermittent, sometimes its fine for ages, then troublesome.


So, as she's wearing oversize tyres, I park her on full height, and put blocks under the bump stops, leaving a small gap. As she senses the drivers front air bag going down, she settles the other 3 to rest on the blocks, lowering about an inch or so.


My theory is the pump is only then having to inflate the bags a small amount instead of empty to full (as she would lower to bump stops trying to level against the leaking bag), and the oversize tyres don't end up sitting on the body (no extended bumps yet)


When parked, I leave the switch in extended height, and there's a trickle charger keeping the battery nicely topped up. Quite often when I come back to her after a week or so, I will have one completely deflated bag, and 3 nice firm bags


Now I reckon that is not doing the EAS any harm being parked like this, but she won't come up at all unless I remove the blocks and lower the car on the jack – this seems to trigger a reaction, and low and behold, up she comes – I noticed this a while ago and was pointed to the fuse box, but is it too consistent for a fuse box fault? Am I actually hurting the EAS leaving her on blocks? When parked, is she trying to level up and getting confused? - there's no saying my blocks correspond to the calibrated heights, so she might never think she's actually level.



The cars a 4.6 HSE Gems, on Arnott Gen 3 bags – the pump is new, the valve block and sensors seem ok (like I say, once woken up, the EAS works fine) – she does have sparodic door/alarm issues at the moment, so often isn't going to sleep properly.


Also, any tricks to sealing an airbag collet before my new pump gets worn out trying to keep up?


Appreciate any assistance,

cheers

Well, it's only day one of 2015, and I've already learnt something new, I had no idea collets were replacable for air bags - I do like this forum - cheers :thumb: ...I shall go shopping.


...any ideas on the not rising off blocks thing? Am I doing a bad thing to my EAS leaving parked like that?

....I'll swap you headaches though, as I need to make new motor mounts for this little 6.0 engine, as the Rover ones are no where near strong enough apparently

ahh, welding, fabrication, machining....that's a headache I'm envious of, give me metal work over electrical any day :wink:

....I can't quite get my head around the concept of LR mechanics going into a sewing shop to buy a crochet hook....

oh, I dunno these days, last Land Rover "engineer" I had look at a car was on a 3.5 Classic - he really couldn't quite understand what the pair silverish things that smelt of petrol on the top of the engine were meant to do...perhaps sewing suits them better than carb balancing :wink:

as for the EAS, thanks for the info....I'll fix the leak and then be able to ditch the blocks, although extended bumps are a must (if I can ever find any decent ones) to stop the wheels resting on the arches.

thanks again

Hey RogerB

Thanks for the tip, that looks a lot more substantial than extending the bump itself :thumb: shall make some soonest once the current piece of the great '38 project is off the lathe :wink:

did you drill the hole axle to retain the spacers in situ or did the axle have to come out for access?

cheers

cheers...fitting Terrafirmas tomorrow so ideal timing,

thanks again

I have 2"spacers under the standard OEM bags and to prevent damage to the bags because of compressing too far and not resting on the 285/75R16 wheels if lowered on its bumps, I bolted a 2"thick disc of the same plastic the spacers are made of onto the axle where the bumpstop touches it..... original bumps stay on the chassis

View attachment 109458
just drilled a hole in the metal plate on the axle, cut m8 thread and bolted the block onto the axle, the updated version has an allanbolt that lays inside the block.

Hi again RogerB, apologies to trouble you once more.

I have been designing and drawing this morning, so, just to confirm my brain is working more or less right before I order billets for manufacture - am I correct in saying in this instance the spacer length under the bumpstop is relative to the tyre size and not the suspension lift - we're trying to prevent tyre/body contact on EAS collapse here so the suspension lift is of little consequence yes? - I've measured the diameter of the standard tyre, compared it to my own, and the difference between the two is the the bumpstop lift requirement - have I got that about right?

cheers again for your help :-D

I'm on 285/75 R16 with a big off set (not ideal, but it had them fitted when bought)

They rubbed on motorway height before I re-calibrated and played with the settings (she still on inhibit now just in case as they're still very close, but the sensors wouldn't let me take her up any more) and the body is well on them when the EAS is down - I reckon the bump extensions is the way forward, combined with new bump rubbers.

Thanks for everyones assistance - I'll post the results when they're made :wink:

An additional trick is to shave the end of the air line with a crayon or pencil sharpener. I tiny little chamfer can make a world of difference in the seal.

HUGE thanks RRToadHall - this little beauty...

...has stopped my leak on the Arnott bag (3 days, no droop), 'tis now an official item in my tool kit - you Sir, is a bloomin marvel :thumb:
