Description
Spray Cleaning System
ENGINE BLOCK SONIC CLEANING
Promar's second process in the cleaning of aluminum blocks is the ultrasonic cleaning method, long known as the "benchmark" in cleaning and engine restoration services. Hundreds of specifications reference an ultrasonically cleaned part as the ultimate target for cleanliness. Ultrasonic cavitation is able to clean right down to the surface of a part and beyond. It is also able to reach internal areas, which are not accessible by using other cleaning means including spray and mechanical agitation. The forceful nature of ultrasonic energy provides the physical "push" required to break the mechanical and ionic bonds that hold very small particles to surfaces. Once cleaned the block is sent for pressure testing.
ENGINE BLOCK PRESSURE TESTING
Promar uses the Delta Pressure tester to double check for pin holes after magnafluxing and dye testing are completed. Cracks and defects not detected during the first process are found at this time. This second process insures the integrity of all castings used in Promar products.
ENGINE BLOCK PREPARATION
A complete visual inspection of the block is performed. Repairs will be made to minor casting defects, removal of broken bolts are performed as well as repair and tapping of threads. Gasket surface repairs are performed to minimize stock removal. The next step of engine block remanufacturing is align honing.
ENGINE BLOCK HONING
As the machine hones, it shows the profile of the bore graphically as it continuously analyzes the bore and senses taper anywhere in the cylinder - top, middle or bottom and automatically dwells or short strokes as programmed, correcting the tight area. As engines continue to get more complex, oil clearances and machining tolerances continue to become even more critical. The only way to keep up with evolving engine designs is to use every piece of technology available to us. Make sure your engine block is machined by the best machine available, you won't be disappointed.
Final assembly and completion of engine block remanufacturing is not started until all blocks go through a final wash.
