EAS Standard ride height

**Nomad9** · 13th February 2009, 10:33 AM

Hi Forumites,
Ok, I've now I believe fixed my solenoid valve block leaks, hears hoping. I'm now trying to find out what the standard road height of the vehicle is. If someone can give the measurement from the recess of the wheel rim at the bottom either where the tyre joins the rim or the wide flat part of the rim just up from the lip of the rim. I'm finding it very hard to get a consitent place to measure from and a consistent measurement from all the forums in the world it seems like. I take the top measurement from the centre of the wheel arch where the lip of the guard bends at 90 degrees to the vertical wing section.

At the moment the measurements I have as a "standard" are 660 mm standard height, 635 mm as Low, 600 mm as access, 700 mm as High and 730 as extended. Either my suspension is way out or I'm taking these measurements from the wrong place. I've put the Ron Becket calibration blocks in and the suspension now flashes between high and standard and the rear blocks remain loose.

Can anyone help me here I'm obviously doing something wrong here but what. I'm using the Faultmate MSV-2 for calibrating the system.

Thanks in anticipation for any help rendered. Yours Marty

Hi Marty

this may help...you need to read the whole page...

Hey Allan, Again thanks for the help, I've now worked out I can only assume how to calibratethe suspension, the calibration blocks workrd to tell me the variance in the height sensor readings. From there I then assumed the right standard ride height and worked out from there. The vehicle now seems to sit level and do what it's supposed to do. I ended up with a couple of EAS faults due to height sensors being out of range, I didn't quite work out how that happend but it did. I reset the faults and everything works a treat. Thank goodness for Faultmate, what a godsend that was.........
I really appreciate your assitance whilst working through this in all the forums we frequent.

No Wuks

Seriously though, thanks for letting us know that you have solved the puzzle!

Which model RR are you driving, Marty?

RRC or P38A?

Here is a link to a drawing of my genuine LR EAS calibration blocks for a P38A:

Hi Ron
The drawings are great! and a mate has promised to make me a set in his newly erected shed complete with a "seriously capable" 3 phase lathe...(for that read "shed envy"!!

My problem is that I haven't a clue how to use them with Faultmate (or Storey Wilson's marvellous s/w) since the blocks' dimensions don't seem to correlate with standard values...

I truly wish some clever bright spark could solve the inner workings of "test book" to enable a prediction of correct "bit" values from calibration block values...

anyone?

cheers

ps : If you travel through UK en route to Switzerland, Britparts can supply much needed electronic bits and pieces at approx 1/2 c-1/3 the cost of our local suppliers !

I haven't yet used the blocks but it appears the blocks fit inside the bump stops so this may affect what you are trying to do.

One day I'll try them out.

Ron am i right in assuming the smaller block diagram has the same dimensions at the top ...... and would that smaller block be for access mode ?
have just bought a Faultmate MSV and Rave CD hope to calibrate new air springs next week.

Hi Ron,
I bodgied up a set of blocks using hardwood.
As you correctly point out, the tapered section is to allow them to feed through the foam bump stop cushions to bed against the actual steel bumpstop. Thus the block sits squarely between the axle pad and bumpstop.
The large blocks separate the bumpstop and axle pad by 135mm
The small blocks reduce the clearance to 70.5mm.

The official LR EAS Systems Information Document for the P38 specifies that standard height is achieved when the bump stop - axle pad clearance is 100 +/-4mm at the front, and 105 +/- 4mm at the rear. NOT wheel arch height

So, I made up a set of blocks to these specs and inserted them.

Surprise: the ground to wheel arch height with regulation size tyres at correct inflation was NOT the 790mm expected, but rather it was 810mm!

Have not figured out the relevance of the calibration blocks (special tool) LR 60 003 to what we're trying to do, other than to guess that they are specific to the Test Book which has LR proprietary software which calculates correct sensor bit values from these (different) reference points....

Cheers
