LC 4x4 Air Operated Diff Locks

[phippsy]

Had a look at the site, but there's not much info on the locker there either, the 'view a pic' of the product linked to a picture of a spoa (?) 60 series cruiser, no pictures of the said locker or diff fitted with the locker.

How are we expected to buy something we cant even see?

look, it has a pneumatic air ram, it's 3 times stronger and 100% better. by my maths that means they are outstanding value at $6273.86 (plus GST) (plus fitting) each. I can't believe you haven't all bought a couple each already.

i may not be able to read and write . but when it comes to building stuff
i out rank the rest .....
i will have to get some one to type up info on my products . so u all can be happy . i am teaching my self to read and write . and using this forum has helped improve my skills (reading and writing) i left school in year 9 .
did my first spring over mod to a G60 patrol . at 14 years old .....
many year latter here i am .....

This is all good and im not knocking you for trying.

But people have questions and if you cant answer them then dont come here telling people you have a better product but not be able to answer them as to why its better.

So it has a neumatic Air Ram. What stops this from developing seal problems? I have seen Air rams fail 100's of times in much better environments than under a 4wd covered in dirt, mud and oil.

Where is the Air ram mounted? How is it protected from damage?

the pneumatic air ram is mounted to the diff carrier bearing bolts . on the inside of diff centre ...
if the seals happened to fail .. all you need to do is remove the diff centre
undo 2 bolts + air line .. and the air ram can be removed .
but if u have a arb set up . u have 2 o-ring on the end of the carrier bearing and you also have interal seal . to replace the seals on a arb locker . u have to split the whole locker to fit new seals .
i know 4x4 shops that have fitted new seals to a arb locker and it still leaked . the way arb iner seal is located . some people who have tryed to replace it have scratched the steel .. and witha new seal it leaks worst than before .... but with a LC 4X4 LOCKER the pneumatic air ram is made for industeral use in oil . in the air ram is a spring that holds it in the unlocked mode . and when it is in the locked mode it assists in faster unlocking .... ..
when u have a locker in the front it is imporant to be able to unlock it , to beable to turn . (that why i developed a locker that unlocks faster.)
if the locker stays locked after being turned off . you will increase the chances of breakin cv joints - axels etc .

i don't have any photos at the point in time . but when i do i will do my best to show you all .
thank for your time ...

just to add .. arb locker are a good product . but i improved on there falts

[pongo]

Actually sounds like a more user/service friendly idea to me.I could be wrong though. I am intrested but like the rest woulkd like to see pictures and specs. As im new to the forum i dont know the history of people flogging off there products here,but would like to ask were can i inspect one of these fine beauties.
As for the engine mount breaky thing, Just use some chain to limit the engine's movement`s.thats how alot of big hp streeters keep the engine still sitting in their car.

Small cyl.

I use the same air ram that jack uses.
but with a heaver spring ....
i looks similar to the one in the pic . but internal it is different ....
use that pic as a reference only ......

i will be building nissan lockers soon >

[HSV Rangie]

need to see pic of internals to compare with the JM unit.

JM runs rings around the arb set up.

will be looking for these soon, (toy).

I think the seller is banned from here

I think the seller is banned from here

in his defence, a mate of mine bought some CV's of him and he said the sevice was excellent. he was a bit of a roughy to talk to (most QLD'ers are) but very help full.

[RUFF]

I think the seller is banned from here

No he has not been banned from here at all.

[nicbeer]

Like to see pics as well. and more specs and comp finish placings if any.

Also are you doing zook ones??

cheers

No he has not been banned from here at all.

My mistake then

All we want is pictures and proof.

i will be glade to show you all .
cruiser park (mud bulls + music) i will have 4 demo 4bys there .

So did anyone check this out?

[Rb25sil80]

Why didnt someone just ring up and ask for some details? Folks on forums are so quick to jump down peoples throats when they make a claim.

Fair enough the guy is probably full of shit but you wouldn't think he would blatantly lie to a legit customer over the phone. If you were actually interested in the product im sure a phone call wouldnt be too much trouble. Businesses get sick of dealing with people asking for pics for email, 99% of them are dreaming time wasters. I should know, im probably one of them!

Cheers

[whiteknight]

Well it wouldn't hurt to throw a couple of pics up on the forum here. 5 minutes of his time whcih would allow hundreds of poeple to check it out. Its not like people have not expressed interest !

[gotoy]

Seven weeks and he still has not posted his pics. Hmmm that 7 weeks old smell is becoming worse.

[joel HJ60]

I'm gonna say he does have something. <flamesuit on!>

[Rb25sil80]

As others have already said, most mechanics, especailly the old school ones havnt exactly made the transission onto the internet smoothly. The guy might be able to post on a forum but capturing pics with a digi cam and uploading is a little more complicated...


Your right though, a few pics would save alot of trouble as he has made some fairly outrageous unsubstantiated claims. Still the internet forums are full of time wasters and I cant say proving myself right to internet geeks is right up there on my list of things to do, especially if I ran a small business.

I've obviously missed a link somewhere to a pic of an installed unit.
Can someone repeat it please.

Question: is it spline operated or ball bearing operated?

There are privately made bb lockers here in NZ that ARE used by most competitors in trials, some winch challenge trucks - excellent for use in the front as they unlock almost instantly, even under full lock.full ,load.
Cost a bit less than ARB. I've had one in my truck for over a year now - beats the ARB hands down.

For trials use they're being replaced now with hydralically operated LSD (can increase pressure to lock) but these are not an option for a 'regular use' truck due to mainenance issues.

nobody knows... out of almost 10,000 members of this board, nobody has come forward to say they've got one and tell us how good it is...have you got more details on how these ball bearing doodads work?

[LUCIFER]

If its got moving parts then its got wearing parts!

ARB has done me well for years. well done to the guru for trying but im still Fitting ARB's no matter what. if its 100% stronger its only going to bust something else!

cheers

[andrewfarmer]

have you got more details on how these ball bearing doodads work?

one side gear has holes in it.
the carrier has holes in it.
a stepped sleeve goes over one end of the carrier, linked to an selector fork, operated by an external air cylinder.

operate - air to cyl, moves fork, moves sleeve.
ballbearings (sitting in holes in carrier) are pushed into holes in side gear
diff locks.
disengage, opposite ari to cyl, sleeve pulls back, bbs come out of holes in side gear
diff is unlocked.

fitting involves a bit of fab work to mount the fork on the diff housing.

because the ballbearings are round, they pop out under load, unlike a spline based locker where normally they will only disengage when there is no torque difference between the axles.
