38,000km, Do I need to inspect/replace the water pump shaft?

    Hi, I'm about to take the 2010 KTM ADV on a month long trek that will be mostly dirt and gravel roads, some in pretty isolated (in so much as one can be isolated in Canada) places. I just replaced the fuel filter as a preventive measure having previously replaced it at 20,000 km. The bike runs great and never gave me any problems (other than the fuel filter related issues) so I'm debating if I need to even check the water pump shaft. I seem to recall that the 950s had mandatory inspection every 15000km, but that doesn't appear to be the case on the '10 990.

    Advice?

    Thanks for the input. Most failures appear to be on the pre 2007 950s. The 990s seem to fare much better when it comes to water pump shafts. I wish I could quantify it. Is there a 1 in 5 chance the pump fails? Or is it 1 in 50? Bayesian probability anybody?

    I changed mine at 30,000km on my 07' 990. It was not leaking but I wanted to use the 08' water shaft kit. If I recall, the 08' + were changed, but not the 07'. It's been awhile so /shurg.

    I've put another 30k on the bike and oil is still good with no apparent coolant contaminants.

    A better approach might be to put a Scott's stainless oil filter in the thing. That's what I have. That way, a failed wp seal will not stop up the filter and you will not lose oil pressure. The engine can run quite a while with no damage to the internals with water in the oil. It's the lack of oil pressure that kills them.

    Ciedema just replaced his at about 35k kms. '11 990. He's bush bashing his way across Canada on the TCAT.
