    Default Xantia gearbox access

    G'day Froggers. Can I call on the accrued knowledge of members and ask is it possible to access the Xantia manual box for repairs in situ'...


    A mechanic friend needs to access 3rd gear on a 97 16v as the synchro is cactus
    He suggests that it appears doable ..any thoughts or experiences appreciated..

    Hmm. If one synchro has gone, and third at that, I'd want the box on a bench and dismantled properly and fully checked, and all seals replaced, then thinking about a clutch while it's out. Just me though.

    Hi,

    I havn't done this on a Xantia (although I do have one) but I have done it to a CX to replace a 3rd gear synchro ring. The job is fairly straight forward. Take the end cap off. Remove the 5th gear stuff and clips that retain the shaft bearings. Undo the main casing bolts and withdraw it leaving the shafts and selector rods in place. If the remaining selectro will co-operate, the secondary shaft can then be withdrawn, disassembled and worked on.

    With careful driving, the replacement ring in the CX last 6 months. Citroen gearboxes use steel synchro rings and they only seem to wear out when something goes wrong with the taper surface on the gear itself. I seems to lose its slippy fininsh and goes rough so that it rips into the synchro ring until it wears out. I have heard of getting weld applied to the synchro gear surface and having that machined back to provide a replacement surface but I think you'd need a specialist to do that.

    I would think it would be better to try to find a good second hand BE3/5 gearbox.

    Cheers,

    Ken W

    Thanks Ken. ( and John ) It would seem nobody available to comment has attempted this... could be a "suck it and see" job.There is a replacement ( used ) box in Sydney for silly money ( 600 delivered )... otherwise its a lift out..Regards Brian

    $600 is on the money for a delivered, warranted item IMO.

    Yes, seems reasonable to me if the supplier is OK. Compared with no Xantia it's cheap.

    Its not a lift out job, but a drop down. I have seen CC use a bar that sits across the engine bay and sits in the drain of the front guards. This has a hook you attach to the motor to hold it up when you undo the mount on top of the gearbox. Also has a small chain block attached over where the gearbox goes so you can drop it down slowly. Not that hard a job to drop the box out of a BX or Xantia

    One of these. A bit over $100 on ebay and perhaps double in a toolshop, so haggle if you want one.

    Very neat. I'd not seen that before. Luckily I suppose...
