    MSX 110/150 - Flywheel puller bolt size?

    Hi Gang,
    Tearing down my MSX150 engine to transfer over to a new block. Anybody know what size the Flywheel Puller Bolt is?

    This flywheel doesn't come off like the Fuji 2-stroke ones. It takes a large threaded bolt to screw into it and push it off the crank snout. I can't find the right size bolt.

    Service Manual says:
    9. Remove the flywheel bolt and washer from the front of
    the engine. Install flywheel puller bolt into flywheel
    PN--PW--46989. Carefully tighten puller bolt until
    flywheel comes off of crankshaft nose. (Photo I)

    ...

    PW--46989 -- REQUIRED TOOL
    MAGNET ROTOR / GEAR REMOVER BOLT
    USED TO REMOVE MAGNET ROTOR AND BALANCE SHAFT GEAR WHEN
    USED WITH PW--46982.
    I can't find any mention of the size. I've tried all the loan-a-tools from my local autoparts store and nothing comes close.

    Cheers!

    Hi ripcuda,
    I'm running into the issue the same issue. I can't find just the bolt anywhere (PW-46989 Flywheel puller bolt) . I ordered an M22X1.5 RH and an M20X1.5 Rh hopefully one of them will work. They should be here by the weekend. I'll keep you posted. They run around 11.00 bucks on Ebay.

    Cool. Thanks! It'll be good to know for sure.

    Randy at WeberPower hooked me up with one for a good price. I'll confirm it's specs when I see it and post them here too.

    Cheers!

    ripcuda,

    The M20X1.5 RH works great I picked it up on EBAY on EBAY from cascade lakes motorsports for 13.75 free shipping.

    I understand these are called bipolar pullers. Any idea what the outside thread specs are. Assuming the inside bolt is M20x 1.5

    Everything.....as previously stated. Looking for a link to a non-$100+ tool is all. The only thing I can find for $14 on Ebay is a bolt. Seems like it is missing the other half unless it is just a single bolt that forces the flywheel off the nose.

    Nope... just a big bolt... that's all it is. The threads are on the flywheel that this bolt engage. Then as you hold the flywheel still and tighten the bolt... the bolt pushes the flywheel off the snout of the crank. It does not thread into the crank. Easy peasy.

    Cheers!
