    my walker mt/20 with 640 hrs, on its third season just quit today like someone turned off a light switch. the dealer thinks the camshaft is history. i have changed the oil every 50 hrs and filter every 100 hrs and taken very good care of it. is this a fluke or is this what to expect from kohler. oh yeah, the warranty is out by 2 months.

    with only 640 hours and just out of warranty you might be able to get your dealer to go to bat for you and get this covered on warranty. For what its worth, having the engine spontainiously shut down and with very low hours just doesn't seem like a cam failure although I don't knnow much about the situation. Also, if it's worth anything, I have had kohler's in all but one of my ztr's and have had great luck.

    Most companies that offer warranties have a "policy" about just out of warranty products. You may call and check it out.

    Unless the cam actually broke in two I don't see this as a problem. Start with the basics. Pull a plug wire. Got Spark? How about fuel? Squirt a little fresh gas into the carb and see if it will start. Compression? Get back to us after checking the basics.

    Hey if you could tell us what engine we are dealing with that would help also.

    its got spark, i squirted fuel down the carb, pulled the plugs,compression seems weak on one cylinder but it was not measured with a gauge. it is a 20 hp kohler. the mechanic pulled the valve covers and cranked and there was no valve movement at all. the oil has been changed every 50 hrs and filter every 100. he said camshaft.

    Does this mechanic work for a authorized Kohler service center ? If so all they have to do is call Kohler and explain the problem,2 Months out of warranty Kohler should authorize a warranty adjustment in which they will supply all the parts for repair and you take care of the labor.
    If they did in fact have a issue with cam breakage they will most likely take care of the whole repair.

    Remember Kohler Factory Trained

    yes, they are kohler factory trained. i hope they will help me out. i would have no problem paying for labor. one good side note: the dealer is letting me use a demo walkbehind until fixed. thank you for the advice...

    After "consulting" with a service specialist at Dixie Chopper I have learned that the timing gears can come loose causing your problem. It is an infrequent problem but it does happen.

    no valve movement?? did he look at the lifters??? that is a common problem.
    you cant tell if a cam is bad without a teardown
