    Fitting a Ashcroft ATB to LT230, parts list and fitting questions.

    Greetings to all within the AULRO Brains Trust
    I've decided I want to drop my transfer box off in early in 2016.
    For the record, early MY12 defender, 2.2ltr, 6speed with a LT230


    I want to check the gearbox->transfer box splines for wear and lubrication.
    I have read that some have failed as no lube was applied at the assembly point.
    Q= Is there a modification that can be done to overcome this?


    As it will be out I'll do the seals(yes it's got a minor leak) while it's all accessible.
    I've learnt in the past if you are doing seals etc. it's worth checking the centre diff shims also, I wore out a set in the now gone Disco.
    I have a plan to eliminate doing this in the future and remove the centre diff weak point.
    After lots of searching and reading I have been given the approval to fit a Ashcroft ATB
    For those that have not heard of them these 2 posts and internal links where handy...
    serious backward step!!
    Review: Ashcroft LT230 ATB centre diff


    Doing the read through the manual's and a search or 5 it seems fairly straight forward on the surface.
    I cant' find the finer details to a question though.
    I'll get the 2 new associated bearings and a lock nut as a matter of course.
    I have access to a press via my son so fitting the bearings should be easy.
    In the RAVE it uses special tools to do a end float/pre load check once it's all together.
    Q=Can this be done on the workshop bench with out the special tools?
    Being a new shaft assembly I assume this would be more critical then if just replacing the bearings on the original set up on a rebuild.


    The parts list...
    Ashcroft ATB X1.
    Seal/gasket kit X1.
    Centre diff shaft bearings X2
    Centre diff shaft lock nut X1
    Gasket sealant.
    Loctite.
    Oil.


    If anyone has any answers to my questions or tips to help this along I'll happily listen.


    PS.
    I have had an after thought for the usual intermediate shaft leak.
    Q=Should I fit a sleave in the housing as is done on the worn housing repair or wait for a few years to see if it leaks again?
    Q=If I do how hard is it to do at home or is at a send out job?


    Thanks in advance,
    Cheers, Kyle.

    I can't give you advice about the procedures cos this work(ATB and master rebuild kit) was carried out by my mechanics but one tip i can give you is to fit a HD cross pin too Ashcroft Transmissions and the final result will be the best then

    Err, you can't fit the HD cross pin if you are fitting an ATB.


    The open centre diff is being replaced so there's no need (and no where to install) any form of cross pin.

    it seems that my mechanic needed one for his car then and knowing how dumb i am in this area made me buy it ... it happens when you are too nice with them

    Thanks Justin,
    I'll text tomorrow afternoon(Monday) before I ring so I don't interrupt your work load to much.

    That will slow the procedure a little but if I remember I'll get some.
    Of course you could come and help so you'll know what's involved to do yours
    Cheers, Kyle

    True, but I have to match what I spend on my car with what I spend on her, and it's getting expensive
