To-20

I am rebuilding a t0-20 continental z120, I removed crank and cam shaft, and am getting ready to re instal everything and have noticed there is no marks on the camshaft to set timing and only one punch mark on the crankshaft.

I did notice there is a s on the crank gear and a s on the cam gear. Any help is much appreciated

If you can't find marks on the gears, you can still time it.

Sit the crank in, temporary the flywheel on. Find the TDC mark through the hole by the starter. Mark the
crank position so you can come back to TDC.

Hold a couple of pushrods up against the #1 set of cam lobes, push the lifters up against the cam. Rotate
the cam until they are in overlap position. Stop when they are both equal, one just closing, one just
opening. Rock it back and forth several times to be sure.

Sit the crank back in at the TDC mark. Rock the crank back and forth, watching that the #1 cam lobes are in
overlap when the crank is at TDC.

That will time the cam to the crank.
