The power stroke is the brand name for the heavy-duty Ford Focus series trucks. You will find them in the super heavy duty trucks. Other than the First series, the power stroke also strengthen the Ford Excursion, Ford LCF, Ford e series, and more. But, the name came from one of the South American truck engine, the Ford Ranger. Ford Motor Company made the power stroke engines in collaboration with the Navistar International Company. Since 1994 the company uses iron, compacted graphite, and such materials to make the super strokes. They also aluminum as a head material to facilitate the reverse flow. Here in this article, we will be discussing more the power stroke engines and their parts to give you a better insight into the Ford engines.
History of the power stroke engines
Ford introduced the power stroke engines as a market competitor of the gasoline V8 and V10 block engines. It is the rebranded version of the diesel turbocharged V8 engines. The first member of the power stroke engine family is the 7.3 power stroke supercharged engines with a quarter ton and more upper versions of Ford e series services. Let’s get to know something about this breakthrough engine.
7.3 super stroke engine
The 7.3 super stroke engine is about a 417 Kg engine that can create up to 275 horsepower of energy with a 525 pounds torque efficiency per foot of space. The machine has both manual and automatic transmission efficiency. The earlier transmission is from the manual set up. It can go as high as 505 pounds torque per foot and 275 horsepower running energy. The oil pan can hold up to seventeen liters of oil usually. The additional 7.3 Powerstroke head stud space holds another three liters for emergency use. At first, the engines were only single shot and used the hydraulically actuated electronic injection systems. These engines run on a high-pressure oil pump to create the oil pressure to make enough strokes at an appropriate angle. During 1994-95 Ford added single turbochargers and an air to air cooler to decrease the air vent from the exhaust and increase the air density. Until 1999 they didn’t get the split shots.
7.3 power stroke troubleshooting
Despite being one of the most reliable stroke engines for lightweight and medium-duty trucks, the 7.3 version is not free from troubleshooting sessions. The most common problem with the power stroke is its camshaft position sensors. It causes sudden engine breakdown amidst the action. You can quickly diagnose a camshaft failure by seeing the movement of the tachometer during the operation. The fuel and water serration valve is another small failure in the 7.3 power stroke version. The aluminum shaft usually shows up some cracks and mixes up the fuel with water, which can cause several problems. Even the interior fire breakouts were frequent events for some of the Ford during the operation. Another shortcoming of the Ford 7.3 power stroke is that the under valve cover harness or UVCH has a poor connection with the wirings. So, the company started providing commenting rods with the model.
Ford had to stop producing the legendary 7.3 power stroke in 2003 as it could not meet the California noise emission limits. The newer 6.4 and 6.7 versions replaced the initial 7.3 Powerstroke engines then.
Since the beginning, the Ford E series is using the power stroke in their full-sized vans. The Ford excursion is using it on the sport utility vehicles. It is a very well-known engine that is supporting the diesel engines very well.
