    Top end rebuild 97 Seadoo XP

    So im redoing my topend on my xp, my question is do I really need to split the cases and clean it all out? The rear pto piston is the one that failed, a few big chunks broke off the top. Luckily I broke it down and was a able to retreive most of the piston pieces. Am I waisting my money just doing the topend only to have more failures from not getting a FEW SMALL shavings out of the bottom?

    Anytime chunks have broken off you have to do a full rip down

    Tear it down and clean it out good. Its also a great time to check out your crank and make sure its 100% good as well. The only way to really check them is to remove it from the engine.

    Ok, whats the best way to clean out all the bearings? Compressed air?

    I would flush them out with something like carb cleaner or brake cleaner, dry them with compressed air, and then oil them up really well.

    I would split the case. I had just redid the top end on my 97 xp cause it ate a piston and was not going to split the cases but i thought i could hear something every now and then rattling around in the bottom end. Its a good thing I did cause when I split the case there was ball bearings everywhere from two of the bearing on the crank that were destroyed. But thats just what happened to me but I would still check it out while you are that far into it.

    Not too mention fresh crank seals and rotary shaft seal won't hurt either!

    When I have one like that I set both ends of the crank up on wooden blocks and use the water hose to flush out the bearings while spinning them. You'd be surprised at all the metal that will be in them. After that blow it dry with compressed air then lube all bearings up good.
