ARB compressor service


New Member
G.Day guys,
I have had my portable ARB compressor for about 5 years and in the last 18 months have mounted it under the bonnet.
The problem I am having is it only pumps to 28 psi now and i now it used to be a lot better.
I have checked hose and connections no leaks
I have plenty of 12 volt power running to it, coming from fully charged second battery ( I always leave car running).
I am running 285/75/r16 coopers but i doubt that would have anything to do with it.

Any ideas, it has been great but not looked after like the rest of the car.:eek:

Inside the pumps there are some values which most likely are failing. Call ARB and they should be able to assist in the parts or repair
