    Ducky, one more thing. How about when the engine is running when the cam sprocket breaks? When everything becomes out of time, do valves hit pistons on this particular OHV kawasaki? I know more about autos than mowers. Some cars are designed in such a manner as causing all kinds of valvetrain damage when the timing belt lets go. Thanks for all the advice.

    They must have clearance because I havent seen one damaged that way yet.

    hey, I was wondering how difficult it is to pull the heads on the kawi. I have a 22 lc that I need to rebuild the top end (leaking head gasket). Curious to where you found the torque spec for the heads? Ive been after a service manal for months and havent got htem yet.

    I got my torque specs from my jd dealer. We get along pretty good and he let me look at his service manual.

    DUCKY, can you post the torque specs for a liquid cooled kawasaki???? I would assume most of the 18-2?'s h.p. lc's would have similiar specs. Just guessing though.

    Is your Kawasaki vertical shaft or horizontal shaft.
    I have the torque specs FD620D 20HP and the FD661D 22HP (horizontal shaft).

    Thanks Ducky

    Liquid, I'm getting my part number off the engine in a few more days. I'll know for sure what it is then. The horsepower sticker fell off when the previous owner had it. So as it stands now all I know is that it is an 18-20something from pics I've seen.

    764 if the cam gear fails the piston will not hit the valve train.

    To test valves, with the valves closed blow comp. air into the cylinders.

    If no air comes out the intake or the exhaust, the valve train is OK.

    Ok guys, my kawasaki engine part number is FD590V. It turns out this thing is only an 18 horse. I'm kind of bummed. The previous owner told me it was a 20! Oh well too late now I guess. Anyone have the torque specs.? This is also liquid cooled by the way. I plan on getting it tore down this weeked to hopefully find a broken "plastic" cam gear. THANKS!
