    Splitting case !

    So I know most of you probably will say get a splitting tool but I’d rather not spend 50+ when the repair Manual tells me to do this . Click image for larger version.

    Anyone got any tips doing it the above way . I’m replacing all trans and crank bearings / seals so hopefully I won’t have to crack her open for another 30 years

    Just do it the way it says.. the key is not to use a pry bar in between the halves.. it should come apart fairly easy with a rubber mallet or dead blow.

    Some cranks are press fit so you have to use a case splitter, otherwise you risk doing more damage than the tool costs. I'm not sure about your 125.

    125M cranks aren't press fit, rubber mallet works just fine.

    I've split a few 125's. clean the outside of the halves on the seam well. get the debris off with a wire brush or rag.
    Take your time, be patient. Just keep working around with the rubber or plastic mallet. If you do not have one, use a piece or wood or another softer medium to place against the case and strike.
    be patient and just keep working around. I've had cases split beautifully in a few cracks, and some seemed like they would never split (until they did)
    haven't damaged one yet.
    penetrating fluid around the bolt holes and stud points.
    Did I mention, be patient.

    do you happen to have one of those duck foot steering wheel covers or a universal puller? some cases can be split using one of these by putting the center of the puller on the crank shaft and bolting the outer holes of the puller to the case. tapping around the case with a rubber mallet as you tighten it.

    I HAVE gone that route before ^^^^^^^^^^^
    I've even made a case splitting tool with heavy flat stock and bolts. they may have worked, but always gave me more anxiety in the process.
    The cases are designed to fit tightly and snugly, and any forces you apply that might go beyond those descriptions always make me nervous.
    As long as you don't take a torch too it though.........

    DAM Shop -It's okay, I've gotten a lot worse than just a thumbs down before LOL.

    ya I think kerosene is a good option its cleans and unlike some solvents will leave a bit of a film to protect from corrosion. just wear gloves and dispose of it properly
