    I got the whole engine ripped down, thanks to instruction posts - thanks. One detail I can't seem to find no matter how much I search, how to split the crankshaft halves ?

    I remove the weights, by removing the bolts, an impact hammer with flat bit helped a lot. But how do you separate the halves, so I can get the con rod off ?

    See enough about people replacing the con rod bushing bearing on the crankshaft end, but no details how to get the con rod off. One thing I read suggested it had to be pressed apart ?

    Any help would be appreciated.


  2. I believe taking the crank apart, you would have to tear up the main bearing. I think heating up the flywheel and cooling the crank pin is how it is assembled. Another problem is getting it trued up after getting it back together.

    Befriend a mechanic!! (it can't hurt)

    the mechanic, down the street, will press apart &/or reassemble bearings etc. for 5 bucks....usually, while I wait. (super nice guy)
    The Maintenance guys at work, would do it, for free! (I'd buy them a soda!!!)
