Hi everyone, done all the tests I can and I think its time for a new pump.
I know your all gonna say theres so many things you can fix yourself but by the time you add everything up, it wont be much less then a new pump.
This one lasted 80k so time to treat the old girl, so where do i get the best deal lads?

just do an ebay search mate,always some on there.
 
Iv been on there and seen a few at very different prices, should i be going for OEM or an after market replacement like the Dunlop one that Iv found?

The Dunlop probably is OEM. Dunlop are not a shabby company anything they make should be reasonable.
 
I bought a seal kit ages ago but it pumps up fine with the relay jumper.
Iv been told it could be the thermal switch and or the bushes?
Changing out the whole unit seems to be the easiest plan.

I had thought about it, but how long has that pump gonna have been run for?
I think ill just be doing the same agin 6 months down the road.
New pump, Im looking at another 80k and piece of mind.

you might aswell get the one from island paul, they are a very good company and i have no issues with thier products, good delivery too.

set up an account with them!!! you'll need one with a p38!!
 
Good news, I rang all the local breakers and found a compressor, which by the look of it, Id say say was nearly new.
Tested it all out first and the difference between suction is massive from my old one so id say the seals were on there way out.
Does anyone know how much pressure the pump should kick out if you put a gauge on it?
All in all the best £50 Iv spent, the old girl has a new lease of life and flys up and down like a whores draws

At least 160 psi:D

The compressor comes on when the air pressure goes below 120psi. If your compressor comes on every 30 seconds you've got a leak somewhere.

My 2000 diesel's compressor comes on every 30 seconds with the bonnet open, I do not have any leaks, it just runs until it pops the pressure release valve. I have an older one that does not do this and a friend with a 2001 model that does.

You would have then to ask the question why does it run every 30 seconds and pop the release valve IF it is full. The blow off valve evacuates the line between compressor and NRV so that compressor does not start against pressure. Theoretically at least the compressor CANNOT run until the pressure held in the tank falls below 120psi. At that point the pressure sensor sends a signal to the ECU to turn on the pump. I think the pressure sensor gets it reading from the very small pipe coming back from the tank. The pump cannot run untill the ECU pulls the relay. That would suggest that you do indeed have a leak which you say you have not, or the pressure sensor is faulty. Looking at it from another view point 30 seconds is not long enough for the compressor to fill the tank from 120 to 150 psi so it can only be pressurising the line from the compressor to the NRV. Cannot see why it would do this. My bonnet open switch is not working, will repair it and if my compressor then starts to run every 30 seconds we can start a new thread. The bonnet open compressor runs club.
 
Brushbox bushing failure:
EAS_brushbox_fail.jpg


This failure is common to all EAS compressor pumps used in Range Rover from 1993 to 2002. It causes damage to the solder joints for the thermal breaker (black box near top of view) and poor support of the armature.
Symptoms are 'short cycling:' pump runs a few seconds and then stops, runs, stops, runs, stops, erratically. It also results in overheating, poor performance, and noise.
