cheers john

There could be a problem with the O ring in the locker itself, it may be out a bit, you will have to remove the locker to check this, if you had it installed by someone take it to them to fix.

does the compressor stay on with the locker turned off? instead of pulling your diff out, firstly remove the airline from the diff end and block it off or kink it over. if the compressor still runs its most likely in the airlocker itself. you can even try and listen and feel around the diff breather with the locker in.

you might even have a crook pressure switch, you might have to hook up a pressure guage to check it doesnt go over 100psi. if it goes over it will be the pressure switch.

Don't kink your air line, this will damage it and it will always kink in the same spot again, just when you don't want it to. Air lockers work at less than 10 psi not 100, if it reaches 100, you had better stand back cause she's gonna blow (if it hasn't already).

your right it will weaken the airline but its a dime a dozen to replace. alot quicker then pulling the diff out. thats the first thing we do at our workshop. i dont know what brand locker you use but with ARB, the compressor cuts in at 70psi and cuts out at 100psi.

soapy water

yes easy I found the main o ring on the compressor was leaking cleaned it up then put some thread paste on . If you turn on the compressor it will pump up the tank on the compressor even before you activate the locker. If no leak found or the pump doesn't come on your problem is after the compressor put soapy water over all connections ,that should be at the solenoid then at the connection to the diff, again if it bubbles it s leaking. However check the hose line it might have rubbing on something that is not so rare that it doesnt happen

 

[croozza]

are you sure thats not foot pounds, as that is alot of pressure, as it only takes a max of 2 seconds to lock in my lockers

 

[BILLBY]

sure it is in psi, the thing is to keep the diff engaged that is under a lot of torque

bainsy is correct the pressure switch cycles between 70 - 100 psi and the locker requires around 100psi to activate.

 

[BILLBY]

It may take only 2 seconds to engage the locker ,but there is not a large void or big pipework that requires filling only the ongoing air pressure on the diff parts to keep them engage

my ARB compressor for my lockers also cuts out at 100psi and not lsb.

For memory Yobbo had a little prob with his air locker at Landcruiser now what did we find out the prob was oh yeah thats right it was the Paul and Frosty problem!!!

My compressor switches off by itself if the locker isn't engaged....once I engage the locker....the compressor continues running constantly even thou the locker is working almost all of the time......

would this o_ring on the compressor possibly cause this to occur? and where about would I find it to check it out.....

I had the same problem - The fix in my case was to tighten the connections to the Pump under the seat. Poking all the crap I have under the seat probably caused the problem.

My dad just suffered the same problem. It turned out to be as simple as the "O" ring inside the diff. Seems this is a common problem with the ARB lockers.

That's what I said in my first post but I got shot down! atleast there is one person out there that thinks the same as me.

Mine played up again last weekend and fixed it today always running. Works out - wait for it - leaking air around the terminals on the presure switch at the compressor. New presure switch and all good again. Spun me out that Air was leaking from there.

I love this site , so much info . I've had my ARB rear locker for about 3 1/2 yrs & the only prob i've had is the fuse for the power to the compressor . At least i now know what else to keep an eye on . Cheers Artie

the O ring

having never pulled the diff out of my truck ,is the O ring a easy fix or something for dealer to service and I believe stupid O rings go in the same s*#t pile as cerclips.

it is a fairly easy job to do, but if you have only just had the lockers fitted, I would get the person who fitted them to do it. The O ring is only held in place by a clip, this has been like that for only a few years now, and the fitter has to get it just right or you will have problems down the track, older lockers don't have this problem.
