compressor myths

[stu]

ive been told that tha arb compressor has two features that arnt so fantastic.

one: is that they get hot under even small use - ie regular locker activation. and for this reason they are usally placed under the engin bay or on a rear tray for ventilation.

two: if you running lockers and you diactivate them you get diff oil running up the lined back to the locker, causes bad smell if fixed to back of cabin., if mounted in cabin

i plan to fix my air compressor on storage system behind my seats, the compressor will be for the operation of air lockers and i just want someone to confirm these myths.

the engin bay is not secure on a TJ.

probably should be under general thread however i may have installation problems when i wire it in myself

Oil smell happens no matter what the compressor, easy fix, run an extension tube off the breather, through the floor of the car, or outside somewhere.

Even $20 K-mart ones get hot. Haven't heard of any ARB's failing, could be noisy in the cab.

I've got mine mounted under the passenger seat (wife loves it ) and I get the smell of the diff oil. It gets hot but all compressors do. Mine fills up a 9kg fire bottle I'm using as a tank and pumps up all my tires and some of my mates too without failing at all.

my ARB comp is bolted to my Draws in my GQ wagon, yes, it does get hot, what you have to expect that with a motor and no cooling system,

i have me locker exhaust lines runngin into the chassis, that is where ARB fit them, so no oil smells,

I plan to install the compressor and feed the two air lines under the storage system through an existing bolt hole made reduntdant by removal of rear seats and along the chassis rails. are the diff exhaust lines installed by them ARB as a standard thing or is this something i have to bleed off the two lines when i install the compressor.

also i plan to feed in a tank to use as a tyre inflation tank. i also want to tap in a fixture so that i can fill the tank from a servo stations air tank. the Arb pumps a low volumn of air and is not really suitable to constantly prime an addition air tank. (so i have been told) Has anyone thrie this too?

okay, when i got my GQ, it only had a rear locker fitted, and the comp was in the enginebay, it was the first style comp ARB release, i had a new comp from previous 4by, so i fitted that into the rear of the GQ, i ran the locker line into the cab and hooked it up,

the exhaust port of the solenoid just released into the cab, and i had no oil fume troubles, when ARB put the front locker in, the put exhaust fitting on both exhaust ports so the exhausted air, was discharged outside the cab,

ARB comps will pressurise a tank, but depending on the tank, the time to fill will vary, the larger the tank, the longer it will take,

if you are going to have a port, so you can fill this tank at a servo, i would recomend you put a one way valve between the tank and the compressor, this isnt needed, as both will only get to 100psi, but i would feel happier, to know, that you are not preassurising the ARB comp using the servo air,

thats just my opinion, others may vary,

i fitted dual TMAX 75 lpm with 4 cubic foot aloy tank in to a mates 4 runner compressors in the back guards running cooling fans tank above the spare with two inch body blocks a bit of a over kill but he wanted something that would blow a 33 tyre on to the rim


ARB compressors are crap you will spend most uf your time replacing seals

The cut-out on the ARB pump is a simple pressure switch which stops the ARB compressor when tripped. If you're pumping up the tank from an external source there is nothing to stop the tank going higher. A pressure relief valve would be a good idea for this sort of system.

Yes, my compressor gets hot while inflating tyres. Mine's mounted under the bonnet (I've got a shorty - the less stuff inisde the cabin the better!) and I always have the bonnet up while inflating tyres. I don't know how warm it gets just doing the diff lock.

well i got the locker in the rear and also got the factory 3.07 diff gears changed to 4.56.



what a difference!! i have use of all my gears again and the pick up is great. instant oomph!



have the 1" BB just need the MM and 35's!

a mate of mine with a rangie come over the other day and showed me how he turned his air conditioner into a compressor! absolutley bloody wonderfull, thats what im gona look into for my GQ it works a treat and my aircon dont work anyway and never has so i wont miss it! we weighed up the pros and cons and by far the compresor was a better choice!

I have been told (I think it by a reliable person) that the only heat issue with the ARB compressor it that it doesn'y have a termal cut out, in other words it will run till it seizes. Most decent pumps have a termal cut out to prevent damage.
