    Hello Husky fans,

    So after my front tire failed (pinched tube or air trapped between tube and tire) at 70MPH I took my Husky to the dealer in Daytona Beach, FL.
    When I finally got my Husky back the bike still did not feel right and had shifting issues.
    My insurance company told me that if nothing is broken in the transmission and the shifting issue is caused by worn parts I will have to pay for the labor to open and close the engine.
    So I decide to have the shop open the engine because I can tell that something is different.

    My insurance inspector said the woodruff key should be completely flat on one side and that the cover over the crank has markings on the inside which indicates that the crankshaft is out of round.
    This is from a 2008 Husqvarna SM610ie with 16,000 miles

    What is my best option at this point?
    I was told that a rebuild would be over $2000 and at best the bike is only worth maybe $4500 if it was running.

    That sucks. :/
    I had my flywheels woodruff key destroyed recently, luckily without any further damage.

    Check for used parts, even ebay or something, 2k is a lot of money..

    What were all of the parts quoted that would make a rebuild cost $2,000? Who quoted it?

    What does the keyway in the crank look like?

    Has the crankshaft been measured? Is it actually out of round? How out of round is it?

    It's really, really hard to tell what is going on from the pictures. The only conclusion I can come to is that the key is beat up.

    Woodruff key was damaged when the flywheel was put on. Key was pushed up then when flywheel probably impact wrenched on.
    Thats no big deal just the mech didn't realize it got pushed up before final tightening.

    If the crank where that badly out of true would have knocked out the main bearings.

    Get a compitent inspector thoes scratches or rubbing on the inside of the flywheel is caused from the metalic sludge build up on the flywheel.

    Have to use a paper towel to whipe it out, shop cloth rag only pushes it around.
    After 2-3 towels use some gas of contact cleaner for final wipe, also clean off the impulse coil because it will have some on it also.

    Just file off the nurded part of the key, it's fine key's only function is for lining up the flywheel not holding it tight thats the nut's job.

    While it's apart should be able to see if anything is worn beyond proper tolenences.

    Only 16k on it it's just getting broken in.

    Put that crank in V-Blocks and spin it with a dial indicator and see if it is out of true.

    Bet it's fine.

    I question why the whole motor was taken apart for a keyway issue that is under the ignition cover?shouldnt a new keyway have been installed and put ignition cover back on and see how it goes?am I missing part of the equation?dan

    Plus one on what George said... willing to bet you can fix or replace that key, proper re-assembly and you're back in business. Most of all, When in doubt, refer to post #11 in the "610 Love" thread. Good luck..
