ARB Compressor

Hi Guys..

I recently sent my Diesel in for a front locker fitment, I had planned on fitting a LOKKA.

The fitment shop called me last week to let me know there was a problem with the installation...

"Good day sir, we are unable to fit the locker you supplied because there seems to be an ARB Diff Lock already installed"

So because the ARB is a complete carrier replacement I am kinda stuck with it (not that I am complaining), so I have decided to get it operating again.

Does anyone have any good ARB parts knocking about that may be for sale? I need everything from the diff to the switch - I am particularly looking for a compressor as this is a costly item.

please let me know if you are able to help.

Cheers
J

JP, nou is ek jaloers.

Maar jy besef dit hoef nie noodwendig 'n ARB compressor te wees nie ne?

Fingers crossed the unit is ok...

Some surface rust on it... hope the seal faces arent pitted.

Been idle in there for many many years.

Die ARB compressor lewer dieselfde druk as die meeste van die ander kompressors op die mark, en minder volume as meeste van die goed wat die 4x4 winkels verkoop.

Dus kan amper enige van daai werk, mits jy versigtig is met die installasie. Wat jy wel nodig het, is 'n "pressure switch" wat die kompressor afsit wanneeer hy druk bereik, en weer aansit as die druk wegval. Ek weet net nie watse druk nie, maar enige ARB installeerder behoort jou te kan se.

Ek sou ook voorste dat jy 'n kleinerige tenkie opsit. Iets soos 'n ou duik-silinder is ideaal, maar as jy nie een kan kry nie, kan "iemand" vir jou 'n silindertjie bou.
Hiervoor kan jy forum-kontakte gebruik, of Arlec Engineering.

Die montering van die kompressor:
Die ARB is een van net 'n paar wat reggemaak kan word as hy kalf, en een van min wat gebou is om onder 'n enjinkap te monteer.
Die kommersiele kompressors het kalf gewoonlik as gevolg van een van drie faktore:
1) Stof. Die filters wat op die goed kom is crap. Koop 'n 5-micron water trap/filter kombinasie. Hulle kos minder as R500.
2) Hitte. Baie van hulle se seels is plastiek. Hoe warmer hulle word, hoe sagter word hulle, hoe korter hou hulle. As jy kan, bou hom eerder binne in die kajuit in, anders, hou hom net tem minste weg van die uitlaat af.
3) Roes. Daar is altyd water in die atmosfeer. As jy die lug saampers, kom (meeste van) die water uit. As jy die kompressor regop monteer (silinder bo), kan dit dreineer, maar as jy die silinder onder monteer, bly dit daar en roes die silinder.

The ARB compressor on my front locker is a "weak" 35 L p/minute.. Not sure what the pressure required to switch it off must be though.
It pumps for 20 seconds, then stops and the I have front lockers .
THUS I would think ANY compressor on the market will work, as long as the pressure switch works correct.
VERY True what Peter Connan pointed out above.. Where to mount it ? Mine is in the engine bay. Don't like it but got it like that so for now it stays there [it is an ARB darem..]

I have an ARB front locker with the compressor mounted in the engine bay. Two switches mounted under the 12V cig plugs under the aircon dials. One for compressor and one for locker. Just like Kagiso - switch pump on, 5 sec, switch locker on. It switches off almost immediately (compared to the back and forth of the standard rear diff lock)

I reckon the ARB compressor is well worth the expense. it is t he smallest one of the range and you were going to put a lokka in anyway! I have run an extension from the engine bay to the rear tow hitch so that i dont have to open the bonnet to inflate tyres and no longer need an extension to get to the trailer.

I have never had the compressor overheat and I regularly pump from 0,8 bar for all 6 tyres. MTCW

For interest ...

Connected a standard ARB orange extension hose and ran it under the car
