    GP1200R. Slight throw on coupler shaft that connects to engine??

    Hi.

    Im currently in the middle of rebuilding my gp1200R. I've got the engine out of the ski and stripped and it was when I was cleaning inside the hull that I noticed that when I turned the shaft with the coupling on it that goes through the bearing housing I could see an obvious throw in the coupling?? It must of been at least 3mm or 4mm. I just don't no if this is normal or if it's tollerable by the rubber coupling that joins the shaft to engine? Any help would be much appreciated.

    Cheers Cameron

    when you say "throw", do you mean the couple wobbles like the shaft is bent, or the coupler can be moved around up and down or side to side??

    Yea, when I turn the shaft by hand the stainless shaft has a slight throw in it like it is bent. Don't no if this is normal or what. Could be the way it's joined onto the other shaft? Or bearing on its way out?

    Bad news, was looking at it closer tonite and where the small shaft meets the long shaft to the impeller it looks like the longer shaft is the one thats bent. Any idea how i split the two?

    Does the shaft normaly take quite a bit of prying to come of the splines? Had the three bolts removed from the bearing housing and was giving it a half hearted attempt but didn't want to do any more damage to it so stopped.

    Cheers

    If you were pulling on the intermediate shaft and making no progress, it's more than likely that the splines are seized. It should slide right off Unfortunately this is pretty common with GPR's. You should be able to find several threads about how people got theirs un-stuck. For mine personally, I had to cut the drive shaft at the thru-hull behind the mid wall. :/
