    Question Loctite Sleeve Retainer 640 - axle shafts into hubs

    Anyone been able to source Loctite 640 Sleeve Retainer < Loctite® Sleeve Retainer 640 > as required by Rave for the axle shaft splines into the hubs?

    I've been around to the automotive stores and bearing shops here and it seems that 1. no one stocks 640, and 2. that it's not even available anymore as it's not in any of the Loctite catalogues we have looked through.

    The closest I have found is Loctite 680 < Loctite ® 680 >, which seems to be much of the same but with a much quicker dry time (24 hours vs 72 hours) and cure time of (20 minutes vs slow cure).


    EDIT: just spoke to JC who has advised not to use the Loctite but rather just an antiseize to stop the rust and corrosion. Apparently they have had a few hubs that they have been unable to separate from the axle because of it and ended up having to throw the whole lot away and replace.

    I note that the Loctite 640 / 680 are High Strength compounds. I wonder if a low or medium strength would be better then.

    Loctite Sleeve Retainer 640 - axle shafts into hubs

    The final version of RAVE on CD which everyone refers to has obsolete information about sealants and lockers.

    For hub to driveshaft use the current LR specification is part STC50554. STC50554 is Loctite 648.

    cheers
    Paul

    Add: disassembly requires heating the part to 250degC and separating while hot.

    I'd recommend application of a hot flame to the part in question. That will do more than cause your eyes to become unfocused.

    Which is best Loctite or Antiseize ?

    Hi all,

    About to replace a rear hub:

    ==> Whats the consensus - Loctite or an anti-seize compound for the shaft spline to hub joint ?

    See other posts here also - LR says Loctite and JC says anti seize - I'm going with JC unless anyone has a good reason not to ! ?

    Thanks !
    Simon
    Cheers

    What JC said!

    You'll thank him if/when you ever need to do it again.
