    ARB Locker replacement bolts?

    I am reassembling an ARB RD03/RD56 (3-piece ARB locker).

    Can anyone see a reason why I cannot use socket head cap screws (class 12.9) to replace the small M8 bolts on the non crownwheel side? It looks like they will clear...?

    Can someone with an ARB manual give me the torque setting for these bolts?

    Cheers,

    Ben.

    Hi Ben,
    Devon 4x4 have done a step by step guide, you can download it here:

    Thanks Tim,

    however I am talking about these bolts

    which aren't mentioned in any of the install guides, as you normally don't have to touch them.

    Most Workshop manuals (Factory) usually have an Appendix with Bolt Torque values by size and grade of bolt, I'm sure I have the info somewhere, but I'm on the way out, I'll have a look tonight when I get back, Regards Frank.

    Thanks Tank, however I have found that ~40Nm for an M8, class 12.9 bolt. Will just have to suck it and see if they clear.

    S'pose you could dummy fit the centre and check for clearance, Regards Frank.

    I only have ARB installation guides they don't give the torque value for those bolts.

    BTW the ARB part numbers for an RD03 are:
    200205 for the 6 bolts
    150401 for the 6 tab washers

    The bolts can be re-used but you need new tab washers.

    Thanks John. The official ARB literature says bolts cannot be reused:
    www.arb.com.au/resources/pdf/airLockers/5-14.pdf

    However the old ones look OK...

    Nevertheless, I have found an alternate solution:
