CK25 engine problem


New member
I have a CK25 with 800 hours on the engine. I changed the oil today, and when I removed the drain plug from the left side, 3 pieces of metal dropped out. Once I got them cleaned up I could see they were gear teeth that had broken off. The engine starts and runs perfectly. The teeth are very shiny, like they are chrome plated. Each one is about 1/2 inch long and 1/8 inch tall.

Can anyone point me to which gear these may be from so I have a place to start looking?

Also, can anyone point me to an engine repair manual?

Thank you,

there aren't that many gears with access to the engine oil. Camshaft, oil pump.
Ebay for the manual, chances are it will be on a CD
