    Pump sealing spacer - Need help

    I have everything back together except I seem to have misplaced the spacer/sleeve that seals the bearing assembly in behind the impeller. This hollow stainless spacer is required to get a proper seal. I can have one made in short order but am curious if anyone can give me the proper dimensions. length, id, od? If you have one on your bench or nearby perhaps you could take the measurements. I appreciate anything you can provide me with.
    Item #23 in attached parts list

    Thank You
    Al

    There are two different lengths of these spacers. The difference is related to which impeller you are using.

    What is the model and year of your machine?
    Stock stator and impeller?

    The spacer behind the impeller not only provides the sealing surface for the dual shaft seals, it also defines how close the rear edges of the impeller blades are to the front edges of the stator vanes.

    On the inner surface the collar/sleeve/spacer seals with an o-ring. Make sure you have that o-ring in the correct position.

    There is also another o-ring nearby on the impeller shaft.

    1997 SLT 780, should all be stock. Impeller #5131371
    I am questioning if spacer was even there. I dont recall seeing it when I dismantled the assembly and have searched my work area upside down. lots of water in with bearing. installed a rebuild kit

    Also can you tell me the torque spec for the impeller? do you use any loctite?
    Thanks

    100 Ft lbs. You can use loctite if you like. I use a little anti seize on mine. The Polaris manual specifies grease on the threads.

    I will see if I have a spacer on hand to measure for you. Sometime later today, if I can find it.

    The spacer provides the base for the impeller to tighten against. Without the spacer the impeller would bottom out on the stub shaft threads when torqued. And possible the blades would hit the stator vanes. The part is just not optional.

    Perhaps the spacer was discarded with the old bearings and seals?

    I removed the shaft, seals, and bearings my self and do not recall seeing any spacer. There is an aluminum spacer between the two bearings but nothing where the seals are. it may have . dropped off when I pulled the shaft out but I have looked my bench and area over and over and cant find anything. I still have the old bearings and seals and it became obvious when I was putting everything together that there was something missing. I looked it up in the parts diagram. I can get one made tomorrow but just need the dimensions. It should be 30mm od based on the new seals. I think the id would be the same as the id of the bearings. just need the length and will be ok

    Thanks

    See this thread

    and this thread

    Apparently 5134505 is the supersede part number for the original 5010295 spacer.

    I have not yet dug into my parts bins. If I have a good used spare, do you want to buy it from me?

    I can mail or courier it to you on Monday.
