How to align the timing of a Cummins rear-mounted single camshaft?

[EdenDella]

To align the timing of a Cummins rear-mounted single camshaft, first determine the top dead center of the first cylinder. Then, remove a screw at the left end of the cylinder block and replace it with a longer screw to secure the crankshaft. If this doesn't work, find another way to fix the crankshaft in place. Next, observe the ends of the two camshafts and insert a hacksaw blade to prevent the camshafts from moving. Finally, align the timing marks on the crankshaft gear and camshaft gear. Relevant information is as follows: Function: The timing chain, also known as the engine timing belt, primarily drives the engine's valve train, ensuring that the intake and exhaust valves open and close at the correct times to allow normal air intake and exhaust in the engine cylinders. Composition: In some vehicle models, such as the Volkswagen Jetta (EFI), Santana 2000, Bora, and Audi, the timing belt also drives the water pump.
