[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]the camshaft rotates 1 times vs the crank rotates 2 times.
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]the piston will reach TRD twice, both times the crank mark is at the pointer
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]once on compression stroke and the second is on the exhaust stroke = 180 degrees out.
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]This means that the crank mark for 0 DTC will be at the pointer both times
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]even with the camshaft 180 degrees out
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]The crankshaft damper uses the same mark for tdc compression and tdc exhaust
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]The stock damper also has marks for 10 degrees ATDC all the way to 10 degrees BTDC
