Outer Limits 4x4 Board

Hi Glen,

This is most likely the result of too little carrier bearing pre-load in the set-up of the diff.

The more torque you put on your axle the more outward force there is on your carrier bearings, and if the pre-load is too light then the diff can actually be forced out of position when the ...

What is the benefit of running 200PSI? Is it faster engagement?

Essentially it is an anti-crash-locking measure. If you flip the locker switch while still under engine power (a.k.a. crash-locking) then the extra pressure will help get the locking gear engaged. If you crash-lock your diff you WILL ...

What is tha max air pressure you can run into a locker before causing problems with orings?

Also what is the usual pressure that the pressure switch cuts out at on a locker only compressor? (little one)

Air Locker O-rings and X-rings are capable far beyond the upper pressure limit set by the ARB ...

After reading the doc you sent me Daniel it looks like the middle blue line (blue line on the top) is the 'exhaust' line that goes into the chassis to vent off.

So the line on the left is the line to the compressor and the black one is the line to the locker (which is the leaking one).

Cant seem ...

G'day Tom,

It's a purge valve made by us for purging air/dust etc out of your compressor.
As all of the lines are connected, there shouldn't be anywhere on the valve for air or oil to come out of.
Check your push-in connections.
The photo makes it look like the lines were pulled quite tightly ...

Whoa! ...there's allot of info asked for in there.

First of all, axles-aint-axles, and even 2 shafts from the same manufacturer with the same spline count but from 2 different models or years have shown to sometimes use different materials and/or heat treat process yielding varying torque results ...

They didn't have the part I wanted on it's own it was only available in a kit form that cost me I think $40 at the time, which is about one 30th of the cost of a whole locker, I got 1 fitting complete with olive, a piece of pneumatic hose and some other little bits that I didn't need. About $8.00 ...

just because no one make a drive shaft strong enough to do it, doesn't mean it can't be tested to failure point. they just need a new test that can.

TESTING

Torque wise, if we could break it with a shaft then it would still be under development. That is our design parameter. The shaft, any shaft ...

Hi guys,

OK, hopefully some clarification for this thread (in no particular order):

1.
The diffs in that video are Toyota 30spl. We don't make the model we tested in that video any more, we got it back from the shelves of a dealer interstate. We only did that because we wanted everything to be ...

my lockers,...seem to enjoy undoing the crownwheel bolts off the locker... arb said it is normal and they need to be checked every 10,000kms...

Hmmm..."normal" is not a very effective way to describe it.
I agree that "normally" you wouldn't worry about your ring gear bolts at all. ARB didn't ...

That seal housing hasn't been supplied with our RD64's for several years now, so if you ever use your vehicle hard at all then I would suggest that your diff is not set up too badly (given years of use), so it just might have worn the bearings and lost a little preload over the years.

If you have ...

If this is a known fault, is there a recall on certain serial numbers or build dates?

We shouldn't have to wait until it fails to have it replaced.

Don't want to be in the bush or halfway through a comp stage and have it fail due to a known problem.

It was totally random and effected ...

Mine failed this week, i had only had it for 6 months and only used 6 times.

What happend was where the shaft that attaches to the bit thats attached to the motor (The bit that goes round and makes the piston go up and down) Is only held on by a 4mm Bolt. This bolt has sheered off.


We had a few ...

Ok that would only work when you are driving though wouldn't it?

If you are worried about water in your diff-locks then this should do the trick.

It splices inline right at the diff.
It turns the air system into a one-directional system ...

So is there a CMLA12 coming out in the future??? Small, medium, large sounds like the next step:)

We certainly set up that possibility. Time will tell. Right now one of the biggest selling features of the CKMA12 is its small size. All the other compressors with comparable flow out there are ...

while your here can you possibly shed any light on this question i asked the other day?

anyone know if its saft to mount these things on their side?

I don't know what the go is re: oiling etc so Im not sure if it could be or if it has to sit upright. I was thinking about mounting it up under ...

CKMA12

'C'ompressor
'K'it
'M'edium volume
'A'ir locker
'12' volt

CKSA12 is the Small version that's not ideal for inflating tyres.

The thrust block is not required for front fit.
It is there for semi-float rears where the vehicle came with an OE thrust block.
You can tell it has one if you look inside the OE diff and see axle scrub marks .
Otherwise they are good for propping up that one table leg that's too short. :D

-daniel ...

edit: dont forget to cut the big fuse holder out and relocate it close to the battery. Some retard who designed it put it in the wrong place :roll:

Cossie,

The fuse is positioned inline as far away from the compressor as could be said to be automatically included in a 'battery next to the ...

No known LSD additive is abrasive

The earliest LSD additive I am aware of being used, which is commonly used today especially in third party additives, are molybdenum blends (e.g., moly grease containing molybdenum disulphide powder and graphite platelets). These are both 'abrasive'. In fact ...

Why don't you guys actually just ask ARB???

Some of them did, and got the opposite advice to what your saying and were recommended LSD oil...

...well, then I guess it would have been good if the guys they talked to had asked! Advice seems to be the only resource the world is not running short ...

Don't use LSD oil, the friction propertys in the oil used to get the lsd plates to grip wear out the o-ring and the oil will leak up through the air line. The o-ring will last about 3 weeks. Just use standard diff oil 90 weight.

If that is the case ARB should be censured for being cheap arses and ...

I have had an order in at my local ARB owned corporate store for a long time but apparently head office wont send them any, and all the ones that become available go elsewhere

Yeah, sorry about that Cossie. Like I said, the projected sales were a blip on the radar compared with what we're ...

I had one of these installed when I had new lockers put in my 80 series 12 months ago so probably got one of the earlier ones with the lower cut out temp :roll: It was installed by an ARB shop and I was told that it is really only designed for the lockers and not for inflating tyres (and looking at ...

What is the exactly flow rate and PSI on these things? Cause I'm sure it can be matched for cheaper than you claim.

Whoa. That is a can of worms that could drag this thread on for months, unfortunately.

I'm not a salesman, I'm an engineer.
I'm not into throwing mud around, so I'll just say this ...

Is it possible to run ARB lockers with another compressor cause I keep hearing more and more bad things about these.

Hi guys, just wondering if I could interrupt and ask exactly what 'bad things' are being said?
So far we're really excited about this unit!
Our market research shows that you'd ...

If that is the case I would say his installer is smarter than the guys at ARB who designed it.. it is folly not having a fuse in ANY vehicle power circut

Right...flame me for trying to help.

OK, I'll bite.
The smaller CKSA12 unit only draws 8 amps on average which makes it perfectly safe to plug ...

Your installer may have added one.

umm yeah, dead short somewhere, if you made that kind of a mistake, please go and buy the small air locker only compressor from arb $250 and you get the loom for free, and if you follow the instructions then no BBQ 4WD to worry about, and the end result is neat, tidy and reliable!

Actually the ...

I don't mean to sound all work avoidant here...but ARB does sell a complete wiring loom for that compressor that will:

1 - power the compressor with the correct gage of wire
2 - integrate an automotive relay into the switch bank to keep toggle switches and pressure switches from cooking.
3 ...
