To set the injection pump timing on a Mack E7-350, first ensure the engine is at top dead center (TDC) on the compression stroke of the number one cylinder. Next, remove the timing cover to access the timing marks on the injection pump and the gear. Align the timing marks according to the manufacturer's specifications, then secure the pump in place. Finally, double-check the alignment and reassemble the components before starting the engine to verify proper operation.
