Tg1860g quit working

[skidd]

Yesterday my mower quit working shortly after starting it. The motor made a loud sound and now turns over but no compression. I pulled off one of the valve covers and the rocker arms aren't moving when I crank it over. Is a broken camshaft common on these Kawasaki twins.

IIRC they had a plastic cam gear and they would break. I'm not sure if/when this happens if it crashes a valve into the piston or not though I guess depending on the compression ratio and cylinder head design it's a definite possibility. However, I know the Kaw engine has a true issue with plastic cam gear. Apparently there is a metal one that supersedes the old plastic one

Thanks for the information. Not sure if I'm up to tearing this motor apart to find out.

Well at the very least you'll have to dig in to replace that bad cam gear. Good luck

You were absolutely correct, the plastic cam gear failed. It also took out the water pump gear. The inside of the motor looks amazing. Very clean. Parts coming later this week. 749 hours.

Any indication of valves hitting pistons
