    Re: Js550 crankshaft part identification? [Help]

    Ok, here is the article about the ATF mod, HOWEVER, DO NOT USE ATF!!!

    ATF will rot your seals and the bearing housing will start leaking within a season or two.

    Do the mod but fill with Royal Pure 15/40wt, 68wt or 90wt gear oil.

    Must be done with the unit disassembled and the lower hole must be drilled between the inner bearings for fluid flow.

    Are you on the same thread?.. You're talking about the DRIVESHAFT carrier housig. This thread is about the CRANKSHAFT.

    Yeah, driveshaft carrier bearing.

    Probably the wrong thread to post about it but it looked like someone was asking about them.

    I do have a question though, I have a crank that is questionable and another that has good bearings but the woodruff key grenaded and ruined the key groove and taper.

    Is this crank repairable?

    Can a crank shop mix and match these two cranks to get one good one?

    crank parts can changed from one crank to another if style is identical.(2 or 3 piece crank).
    but if you're going to do this,you may as well put new bearings too!
