Description

ENGINE BLOCK REMANUFACTURING

TIG Welding Aluminum Heads

After welding, the head must be allowed to slowly cool. A long, slow cool down relieves stress in the metal, which if not relieved could lead to cracking.

After the head has reached room temperature, it should be pressure tested to check for leaks. Coating the inside of the water jackets with sealer, or adding sealer to the engine’s cooling system after the engine has been installed can provide additional insurance against future leaks.

ENGINE BLOCK DISASSEMBLY

All blocks are visually inspected for casting defects prior to their disassembly and the beginning of engine block remanufacturing. The parts are then removed and individually inspected for damage and cause of failure. The oil and water passage plugs are removed to insure optimum results during the thermal cleaning process.

Only premium castings are used for our marine blocks, all castings are replaced in all salt-water applications. Our high performance engines are built with premium cores. In many applications new castings are used, as we never employ repaired castings or sleeved blocks.

ENGINE BLOCK THERMAL CLEANING

The thermal cleaning system gives our customers the closest thing to a new casting, taking engine parts to a whole new level of clean. The heaters emit uniformly controlled heat, which is evenly distributed throughout the chamber. This method totally eliminates the concentration of intense heat or flame entering the chamber, which could overheat, warp or melt parts. The load is heated to 650-800 F (340-427C) in an oxygen deficient atmosphere, where the combustible hydrocarbons decompose and parts leave the oven completely dry. This baking process used on cast iron blocks only employs the Ace RKE 230 oven. Ash residue is easily removed by stainless steel shot blasting which is the next step of our engine restoration services.
