    Default GS Rzeppa dismantle hints?

    Hi folks,

    Advertisement


    Trying to dismantle GS Rzeppa, outboard.

    The 2CV ones have a plug in the housing that can be pushed in to get access to the retaining bolt of the inboard shaft..... allowing the shaft to be removed, and the joint disassembled.

    The GS housing has no plug like this..... how do we get it apart?

    Thanks in anticipation....

    The GS joints are more like those of a CX than the weird 2CV set up. THe drive shaft is splined into the central spider of the joint and retained by a circlip,not a bolt. I assume you have the shaft out of the car?? Remove the ligarex clips and slide back the rubber dust cover as far as possible. Use a vice to support the outer joint housing against the flat surface enclosed by the dust boot. The vice is not tight. You are only using the jaws to rest this surface against. Now using a sharp movement pull hard on the drive shaft to force the circlip to compress and release from its groove. Probably best to have a helper to hold the stub axle end to prevent it dropping on the work shop floor when the shaft and circlip releases.
    When refitting be sure to only push the shaft in until the circlip engages in its groove. If you do it carelessly the circlip can go past the groove and expand behind the spider. Then to remove it the circlip and possibly the spider would have to be destroyed.
    The rule of thumb is to proceed slowly and feel the circlip engage!
    Good Luck!
    Cheers Gerry

    Thanks Gerry I'll give it a go...

    Interesting about the workshop floor... What workshop and what floor? Will a patch of weeds do?

    MMMMMMMMMMMMMMmmmmmmm

    Doesn't seem to respond to a "sharp hard pull"... at least not one that I can exert manually.

    So, is it possible that the shaft has been pushed in too far already?

    Surely good design would make it impossible to assemble incorrectly, or get pushed too far later?

    Can it be pulled apart by chaining the outboard spline to a tree, the inboard shaft to my truck, and drive away?

    Now that I have the 2 types apart.....

    The internal bits... spider, balls, carriage are identical.

    The 2CV one even has the circlip groove, with a circlip firmly in it... to provide a stop for the end of the spline, against which the bolt is tightened.

    All this answers my reason for making the comparison.... I find that I can fit a 2CV outboard end to a GS inboard shaft!

    The reason will be revealed in due course..

    Hey Bob,

    This Franken-Cit, is it going to look like a DS pedal car? I hope so.
