Guys,
has anyone ever found a link to a repair manual for a 32 spline air locker ARBRD64 (or indeed any model) ?
I have combed the 'net to no avail and will have to tackle this if and when I get the parts :evil:

I have an RD64 in the rear of my 100 but I think it only came with installation instructions and an exploded diagram. I don't know if I've ever seen a repair manual as such?

Thanks Jon - the exploded diagram is better than nothing (and I have the original installation manual too) but I am really after more details if poss - have you (or anyone else) ever stripped down an ARB? At this stage it is all conjecture, as I have a long time to wait for the parts! I will also ask the ever helpful Devon 4x4 who are supplying the parts. Between that and my "ggrrrr ggrrrr" noise making truetrac front I am a bit fed up with after market traction aids.

I got this off the net somewhere: www.mudtoys.com/manuals/2-RD64.pdf but from what I can remember it's no more detailed than the printed documents that came with the ARB :( What's wrong with yours then? I've not been any deeper than fitting the ARB carrier to my diff I'm afraid but how hard can it be to strip :mrgreen:

I don't know what is wrong with it but I suspect a seal (the O rings) or the copper pipe... When actuated it just vents air out the axle breather and won't lock.
Haven't opened the diff yet as I don't really want to go through all that until I have the parts. The o ring carrier is going to take a while to arrive though. But you are right - how hard can it be :?
hopefully the hardest thing will probably be getting hold of a dial gauge!

I'd check the seal at the case fitting before taking the diff off if you haven't already? The little o-ring in there is quite a common failure and doesn't need the diff taking off to change. Did you fit the ARB yourself?

they aren't the most complicated of Items

Stick a post in the lounge bit of www.innovate4x4.com (its a small competition forum used by few of the UKs best winch challenge boys, who can strip and rebuild ARBs in the their sleep!)

Yup - fitted myself... :(
However I firmly believe it is not a fitting issue as it worked fine for 30K kilometres and then just started. Then again maybe!
The small seal I did check, as I really didn't want to do all that palaver with cone washers and heavy lifting. I will just get on with it when I receive my parts. Stupid amount of dismantling though for what is probably a tiny bit of rubber or whatever. Thanks anyways chaps.
