Does Ford Power-stroke Diesel have a timing chain belt or other?

The Ford (International Truck and Engine) Powerstroke engine does NOT have a timing belt. It is a gear drive setup. The crank and camshaft gears are 2:1 reduction, so that the cam rotates one time for every two rotations of the crank. Timing is via a camshaft position sensor mounted in the block, that counts small Windows in the camshaft gear via a hall effect magnetic pickup. This timing info is relayed to the PCM which then instructs the IDM when to fire each injector.
