    The only reference I see is the part number 161795801, does this tell me? I can't see a seal size in that, am I missing something?

    Me too. I may just have to take it apart but I don't have access to a local bearing shop within 100kms. I was hoping to have a friend pick one up in Canberra but time is running out before the Yass Vinduro next month.

    "Crownie" for the guys on the other side of the pond is a well (arguably) made beer here in Australia!

    If you can get the seal out. your friend can take it to the bearing supplier. If you have a vernier caliper, you can at least verify the shaft diameter. You need to give correct seal dimensions or it will not fit. My bearing supplier wanted the seals I was replacing so he could measure them himself to assure the fitment.

    I'll remove it today and see if it has any sizes marked on it, I suppose a double lipped seal would be ideal?

    8x18x5 is the size for future reference.

    Buy sealed bearings and leave the seal on the bearing next to the waterpump seal.
    This stops any leakage getting in your bearings.

    When I pressed the bearings out, one had both seals on it and the one next to the pump seal had one seal.
    I thought that was a little odd, is that what you meant Mike?

    Yep but I take all the seals off except the outside one so the oil can get at the bearings.
    If you take that outside one off then oil will come out the waterpump overflow.
    With just one seal the oil will leak out while the bike is on the sidestand and that is why there are 3 in yours.

    Very important to use coolant premixed with deionized water. Coolant not specified as safe for aluminum will start the corrosion process all over again

    Quality coolant will be used, I've had a magnesium clutch cover rotted out in the past, this one is aluminium but as you say, even it can corrode with the incorrect coolant.
