    Loud Squeal and then Smoke - Part II

    Now that my P-X 260 is back together and running strong, it's time to get going with the RXT. This thing has been sitting idle in the garage for far too long, and BigDaddyRXP needs his shop cart back ASAP!

    I'll be pulling the motor this week. But I need to know where to look and what parts will definitely need replaced. Obviously the PTO gasket gets replaced along with the oil pump housing gasket. If I do not see anything odd in the PTO and I don't find any metal shavings in the oil screen, is there anything else I need to look at?

    The ski has run for about 15 seconds without issue, following that initial startup. I'm 100% sure that the white smoke was from oil & XPS, but I'm still not sure about the loud screeching sound. SC is intact. Pump looks fine. Will check motor alignment tonight before pulling the engine.

    He was rear ended in a bad wreck and both skis took impact damage from the rear. Another vehicle slammed his trailer.

    OK, sorry to hear.
    If the motor was running good before the damage from the wreck then what would be the issue with the motor to tear it apart for inspection for metal shavings.
    Unless damage was done to the motor.
    First thing that would come to mind is if some how drive shaft was forced into the motor.

    Hard to really say what you need to replace or where the noise is coming from.
    Good luck getting it back and running.

    Most likely the pump took a hit and shoved the crank forward into the thrust bearings. The hull could have flexed more then enough to cause this and would require splitting the cases to find out for sure.

    I finally got around to pulling the motor. The rubber stopper off of the drive shaft looked perfectly fine, so I'm further doubting that the drive shaft was pushed forward at all. But at this point, I've already got the motor out so I'll be purchasing an engine stand tonight and then proceeding with removing the PTO cover and the front oil screen cover. Later on I will attempt to split the cases.

    Couple of questions. Is there anything that needs to be done to re-bond the exhaust manifold to the motor? Does anyone have any photos of where the motor gets split, or the best way to go about doing it?

    No bond or gasket for exhaust manifold.

    If first time splitting the cases I would take pics, get a manual and label parts when disassemble.
    Its not that difficult but will make it much easier going back together .
    Once you get the pto cover off you will see were the cases split.

    Any idea how much stuff I'm going to have to pull apart in order to see the thrust bearings?

    just the lower half of the cases and you will see the thrust bearing, just be careful with the case plugs, i understand they can be a bitch if you strip one out or theyre really corroded in place
