Details:

This finishing process is used by Prom to remove surface contamination such as rust and irregularities from engine blocks during re manufacturing. At this point the engine is primed with special lubricant and a new oil pump. This automatic honing machine takes any potential operator error out of the equation. The block now receives new lifters, push rods and rocker arms which are adjusted a second check completed by an assembly manager.

With twice the spraying power and a dramatically increased number of multi integrated spray nozzles, this state art system assures Prom that all oil, dirt foreign material is removed from even smallest oiling holes. The load is heated to 650-800 F 340-427C in an oxygen deficient atmosphere, where the combustible hydrocarbons decompose and parts leave oven completely dry. The result of this method is a cleaner smoother surface finish to make easy the detection and subsurface casting defects during quality inspection. Our high performance engines are built with premium cores.

Once cleaned the block is sent for pressure testing. The first option is delivery to a business with forklift readily available. When milling a block it is essential to acquire proper Ra finish for each. The Ra tester is used to check all cylinder bores, crankshaft journals and gasket surfaces.

As the machine hones, it shows profile of bore graphically as continuously analyzes and senses taper anywhere in cylinder - top, middle or bottom automatically dwells short strokes programmed, correcting tight area. The heaters emit uniformly controlled heat, which is evenly distributed throughout the chamber. All engines are custom built. It is also able to reach internal areas, which are not accessible by using other cleaning means including spray and mechanical agitation.

This engine has been remanufactured by Prom Engines and comes with a 3-Year Unlimited Mileage Warranty, ensuring long-term reliability performance. The next process is pressure testing, but first, let us explain how aluminum blocks are cleaned, tested and checked for casting defects. This computerized probe takes all operator error out of the setup process. It also allows for sensitivity control and stone wear.

Each assembler does a visual inspection of the block, heads, crankshaft and all-inclusive parts prior to assembly. The assembly manager then conducts the final inspection of engine. This Ultrasonic Cleaning Method is long known as the benchmark in cleaning. The oil and water passage plugs are removed to insure optimum results during the thermal cleaning process.

Hundreds of specifications reference an ultrasonically cleaned part as the ultimate target for cleanliness. All high performance engines are fitted with ARP strength bolts and nuts prior to rod reconditioning. All parts such as crankshafts, bearings, cylinder bores, pistons, rings, connection rods, main saddles, lifter and camshaft bores are minced for proper size. Once the parts are cleaned, they now ready to be assembled in our Prom engine.

This is accomplished by metal shot pellet's acting like miniature ball peen hammers as they strike the entire surface of block. This method totally eliminates the concentration of intense heat or flame entering chamber, which could overheat, warp melt parts. Cleanliness of the aluminum engine block is essential to insure an accurate inspection. Gasket surface repairs are performed to minimize stock removal.

Prom engines are secured onto a wood en pallet where vulnerable parts protected from damage by corner covers. Ultrasonic cavitation is able to clean right down the surface of a part and beyond. This machine is set up to automatically determine Ra finish based on the type of block, be it aluminum or cast iron, and by gasket used for each specific application. Each assembly is supplied with new high quality bearings and each journal clearance checked plastique, torqued double-checked.

In many applications new castings are used, as we never employ repaired or sleeved blocks. Once reconditioning of the rods is accomplished next step engine restoration honing cylinders. Absolute cleanliness is necessary for the next step, which final assembly. The next step of engine block re manufacturing is honing.

Cylinder heads are then installed with new head bolts and Felipe or Victor gaskets. Each block is fitted with new full circle cam bearings, oil restricts, relief valves, water and plugs. The forceful nature of ultrasonic energy provides the physical push required to break mechanical and ionic bonds that hold very small particles surfaces. Ash residue is easily removed by stainless steel shot blasting which the next step of our engine restoration services.

All engines come with an installation manual. As engines continue to get more complex, oil clearances and machining tolerances become even critical. The crankshaft is fitted in the block with new high quality bearings and each journal clearance checked plastique, torqued double-checked. The entire block is wrapped in a durable plastic sheath to protect your engine from outside elements.

Each cylinder is then accurately checked for seal integrity to assure no compression or water leaks. To retain your classic cars original block casting, Prom employs the artistry of our skilled casting repair technicians. STEP 1 ENGINE BLOCK DISASSEMBLY All blocks are visually inspected for casting defects prior to their disassembly and the beginning of engine block re manufacturing. This second process insures the integrity of all castings used in Prom products.

This machine has a wireless probe that automatically identifies the block, levels measures deck height cylinder bore sizes. When milling we utilize CBN cubic boron nitrite cutters, which are second in hardness only to a diamond. Make sure your engine block is machined by the best machine available, you won't be disappointed. A new camshaft is then fitted into cam bearings bores and all timing components are installed double-checked by an assembly manager.

Each new piston is checked for proper clearance in each bore. The parts are then removed and individually inspected for damage cause of failure. To insure stress free casting, the preening process is used to impart compression strength metal parts. Bulletins about your specific engine are also enclosed in the packaging.

New rings are then fitted in each bore to assure proper end gap. The rings are installed on the piston and assembled into bores. Final assembly and completion of engine block re manufacturing is not started until all blocks go through a final wash. This procedure, as part of our engine restoration services, assures the highest quality cast iron blocks.

This baking process used on cast iron blocks only employs the Ace RKE 230 oven. The residual parts of the gasket set are sent along with engine. After the blocks receive a final wash we clean all parts ultrasonically.
