Valve timing question

Posted by Super8 On 2018/12/21 6:42:29

Hello,

I am reassembling a Super 8 1933 engine. I am in the stages of setting the camshaft position in relation to the crankshaft.

The camshaft gear has two "O"s stamped on its face. There are no marks on the crankshaft but there are some on the harmonic balancer. There is also a sheet metal tab pointing at the damper when the timing case is closed.

I believe that I can set it by bringing #1 piston to TDC at the point where both #1 valves are closed and number 8 exhaust
valves would Just finish closing.

I do not understand however the purpose of the two "0" on the camshaft gear. There are no marks on the chain or the camshaft. Should there be one?

Thank you for any input

Super 8
