    I hate rear seals right about now

    Rear seals blew out in an SBT-motor 98 XL1200. Pull motor, flip upside down, open cases, clean SBT's black liquid gasket and I'm ready to install 3 new OEM seals. Careful to lift crank only enough to slip seals on and dang if that son-of-a-gun won't go back down. Get pins lined up, one end down, pop it with a rubber mallet to seat other end, but then previously seated end pops up. Finally think I have both ends on pins, try to put bottom case back on and it will rock side to side. Hung up on something in the middle of crank. SBT put 5200-substitute everywhere so I'm guessing that's what stopping the crank from seating.
    Guess I'll have to take the top end off, again (just replaced pistons a month ago), and see what the problem is.
    Geez, if I want to get frustrated like this I might as well go play golf!

    There are pins that need to be aligned on the two center bearing spacers.

    I also think the outer two bearing pins into the case and not the case half notches.

    The pins on either end are at 12 o'clock as the motor sits in the ski. Don't know where the crank spacer pins are but I can turn them and get the slightest movement so it definitely feels as if they are in place. Only picked up one end of crank at a time.
    There are two holes on the flywheel bearing. I assume the one closest to the flywheel is the one to receive the pin.
