New EAS Compessor Option

[CaverD3]

New part number for the AMK version:

LR0443600 Should be less $ than the old one too.

Hard to tell if it still has a dryer!
Must have surely.

Having said that I'm not sure if I'd want to be one of the first to have one.

Hi Rich about to send you a PM about it.

I will have a look at mine and see which one it has.

I had the AMK fitted a week ago based on bulletin LTB00420/2011. No suspension faults since - as you would hope to expect. Definitely easy to hear it operating.

Looking at the link above it says that they are a closed system. If so, then that may be the end of the dryer issues - hopefully. Have to stick my head under the car to see if I can work out which model it is.

I just wish the air compressors just had a bit more oompf - yes the standard offering does have the psi and volume to raise the vehicle in ideal conditions but if circumstances require a couple of cycles in quick succession they soon run out of puff. So a compressor with a higher duty would be much better.

LLAMS highlights the issue - if at access height and air tank depleted the air compressor will not get the car to off road height +50 in one go - it will need to have a rest when it gets to about normal offroad height. As a consequence where ever possible I now raise my car in stages - LLAMS +50 then later if needed switch to offroad height.

Does anyone know what happens if the air compressor has failed but the airtank is still full if the car will still raise one last time or does the fault systems just shut the whole thing down?

Re the link to AMK, is our 3 compressor a variation of one of their listed models?

What I was really wondering is if the AMK for the 3 was a single stage like the Hitachi, or two stage. My view is that no one has yet made a long life cheap 220 psig, (15 bar), single stage compressor. Hopefully I am now wrong.

I think I see an air dryer bit - maybe the top sort of rounded thing in the link; the bottom being the motor and the end being the compressor. My guess is the compressor for the 3 is the little one, the single stage LFK EK13. To quote from the link:

LFK EK 13

The LFK EK 13 is a cost-effective, powerful single-piston compressor for pressure levels of up to 15 bar. It is a device that is ideal for integration into applications at single-axis leveling systems.

Can't see it being enough, just for rear self leveling suspension. The LR one is huge, look at TLOs photos. I was thinking it might be the LFK21-0.7 (HP) which would mean the LFK21-3 (HP) might work.

I would like to think that as well - that the new compressor is a two stage similar to the LFK21. If so, then there is a good chance that the new one will be better than the Hitachi single stage. (My fear was that it would be similar to the EK13.)

It looks like the LFK21 would pull about 35 amps, (455 watts), so that sounds OK and I imagine on the LR version, the sensors within, with the appropriate software will all speak Land Rover so we might finally have a winner. If so, I think then compressor problems will start to revolve around the air dryer.

I got around to taking a look at the new AMK compressor installed last week and it looks like it hangs down quite a bit. There are other parts of the under body that hang down as far. It looks like Gordon will need to design a new protection plate to suit! I wouldn't expect the plastic cover to last with tough off road action....

Anyway have a look and see what you think:
