To set the timing for the Isuzu 4HF1 engine, first ensure that the engine is at top dead center (TDC) on the compression stroke for cylinder one. Then, align the timing marks on the crankshaft and camshaft gears according to the specifications in the service manual. Once aligned, check the timing of the injection pump and adjust it if necessary, ensuring the pump's timing mark aligns with the specified mark on the engine. Finally, secure all components and recheck the timing before starting the engine.
