Thread: EAS pump replace with ARB ?

Why would you introduce another airline & source into a system that can fail as a a result of leaking air? Me? I'd do up another Thomas compressor (or buy the equivalent or a bit bigger) to replace the old one if you think it may fail.

$307? Not for me, and we've got 2 air suspended RRCs in the family.

.. Because in the first flush of enthusiasm for my new toy...I lashed out $600 to have my pump (properly) re-built... "Everything" except new motor mounts which were'nt available at the time... The valve body was pronounced "good" at the time...

When replacing my springs I've used FESTO fittings and lines throughout, none of which will leak for a Very Long Time... A couple of $$ extra per piece is a small price to pay.

Getting a bottom massage every time I start the beast has gone from novelty to annoyance, especially to SWMBO, and if I've forgotten to turn off the system overnight it seems to go on forever...

But look on the bright side, the suspension is so slow to pump up to its full height, so I suppose its good that you're slowed right down when amongst the interesting terrain...

I've come to understand that everything apart from the suspension has been built down to a price, often barely able to do the job. A good case in point is the 'plastics' used. The dash is so thin and brittle it sounds 'tinny' and breaks easily.
-NOT inspiring for up-market OR working vehicles.
Never mind what the sun does to it !

Thompson also make a 1/4 hp version, the RR one is 1/5 hp, so why would I waste money and fix a marginal one again? Seems more logical to fit a bigger and more reliable one.

Which is why I'm asking if ARB sell a bigger/better/cheaper one. Or anyone else.

Investigate the Thomas compressors site - US - to get a hold on the size/type/mount footprint, etc of the alternatives. You should be able to measure the originals in the case without taking the car to bits!

We replaced the mounts with the equivalent from Mackay Rubber (I think). Inexpensive and very effective.

Wot ? - do something to the beast *without* pulling it to bits ? - Heresy!!!

(the mounts arrived 2 hours after last post...)

Sorry to bring a P38 into this thread, but I've had similar thoughts to you in regards to running an ARB or similar compressor in series with the factory one to pump her up quicker. I'm not experiencing issues with my EAS, however I figure that if i'm going to get lockers i'm going to be using another compressor!

Not sure if the classic RR's run an air dryer in line at all either, but I dont believe it'd be too hard to make up a Y piece to run the ARB unit through the dryer as well as the factory one.

I'll keep my eyes on this thread!

G`day ,

i think thomas is one of the few that the working pressure is within there realm .

Ours has a p38 compressor , pumps the same as the classic but the motors larger/longer , requires making and moving a mount because the p38 use 3 and the classic uses 4 rubber mounts and a bit of swapping because of the different inlets and i think the wires are a different locale .

Our original had what i thought to be crook mounts or the way the mounts were assembled but the only way to cure the vibrating noise was to replace the pump bearing .

If yours is taking a long time to pump up there`s probably something wrong .

Don`t really notice ours anymore and when it`s started after itself leveled after shut down , it springs/jumps back up to normal height .

If it`s lowered to access it doesn`t come up till it moves .

I've been told that the ARB pump, (around $307 or so,) same as the one they sell in a plastic tool-box but with slightly larger tank, is the direct or better equivalent of the Rover one.

I'd like to run it in series with the EAS one, the idea being to refill the airtank in a shorter time.
With a bit of luck, this shorter running time will extend its life...

Any thoughts on this ?

The EH, - '95 Classic Vogue SE with *working* EAS and Cruise control....

if you've been able to stem all leaks, then the refurbed EAS pump should last you several years since it will need to do much less work... in the meantime you can spend your hard earned on something else!

"... I'm not experiencing issues with my EAS, ......."

- yet...

Yes, the 95 Classic has an air dryer in the mix...

My idea was to run the ARB or xyz - from the back, and feed INTO the (original) line to the air filter. Then put a half-way decent fiter in front of the ARB/XYZ !

This would effectively - I hope - pre-pressurise the RR pump to the tune of,say, 30 psi which means that the flow into the holding tank will be that much faster.

Not run the accurate figures at this point, only the 'concept'.
