    will watch this re-build addo, i have a old xm pump that had a small leak from the seal,
    will get to a press and pop it apart,also i think the reno pump has a different offset pulley but if so it would only
    need a 605-xm one pressed on.
    like you said they are hard to get and expensive, but i see the later 24valve ones are cheap and easy to get.

    Is the bearing that long thing in front of the impeller?

    Yes, it will have two rows of ball in it, the rest is open space (presumably once full of grease). There's no weepage or pressure equalisation holes in the shell, although the casting has both.

    Shaft dimensions are:

    105mm tip to tip
    25mm shaft protrusion to tip, pulley side
    15.92mm shaft diameter, pulley side
    30mm shell OD
    38.75mm shell length
    45.47mm shaft protrusion to tip, impeller side
    12.04mm shaft diameter, impeller side
    42.16mm length, reduced section for impeller

    The stepped seal has a reduced diameter equal to the bearing shell, outer diameter (unverified yet) about 37mm. Its assembled height is approximately 20mm.

    I possess no ideas of propriety about what's posted here, and would be delighted if someone else felt like chipping in with bearing sources or seal options.

    I am not sure I understand the seal construction.

    These are about the best examples I can find without dismantling.

    It's very like the old pumps we fogies used to re-seal every couple of years and occasionally had to re-bearing. Smart buggers use to fix 'em before the bearing went. (Morries, Landies, etc etc). They still use a similar carbon seal in some non-auto water pump casings, so pump repairers might just know a source that fits if the auto people can't come up with one. One would hope that PSA used a standard part, but if they could save even 1c per unit being special, they would do that.

    Hi Addo

    Can you see any numbers on the bearing & seals. You can put the numbers into Google and sometimes find what you are looking for.

    Just thinking aloud...
    I wonder if there is a pump/seal kit for another vehicle/marque that can provided a donor seal. Finding the vehicle will be the issue .
    The mob in the link mayl want to sell a few hundred/thousand.

    You may find a donor pump with a suitable seal at a price that is practical to sacrifice it.

    You could always ask for a sample for extended testing in your road lab.

    All those possibilities had crossed my mind! I'd also thought of requesting a contact point for a volume purchaser or stocking agent.

    Some good advice came from CitroŽnfan; request engineering dwgs from the supplier just to be sure of suitability.

    The good thing about this problem is it doesn't require such an urgent fix as the alternator! I will be asking for help from the DK5ATE engine crowd, this is the "big four" diesel of the PRV's era and I would put a good amount of faith in the pump shafts being compatible.

    addo, did you actually (successfully) rebuild the pump?
