The name Precision Bilt is well known in the field of cylinder block and casting repair. The methods used have their roots in almost 50 continuous years of cast iron repair experience within the same family. This expertise, combined with pride in workmanship, forms the basis of the excellent reputation Precision Bilt has earned in the field of casting repair. Throughout the history of cast iron repair, attempts have been made to introduce a variety of new techniques into the marketplace. Efforts to popularize such techniques have led to claims that they are technologically advanced, inexpensive and require very little expertise. Each of these techniques has usually enjoyed a limited amount of success for a specific type of repair. Such success is usually followed by attempts to use the methods in areas of casting repair that are beyond their limited capability. This, in turn, has led to unsatisfactory repairs that have ranged from a mere nuisance to costly equipment failures. Only one method of repair has withstood the test of time and proven itself consistently effective in all areas of cylinder block repair. This method requires the slow preheating of the entire cylinder block to a temperature of about 1000° F. Prior to the preheating, the area to be welded is ground out and specially prepared. Once the casting has reached the desired temperature, it is maintained at that temperature during the welding process. Using a gas fusion process, a specially trained welder begins melting and flowing cast iron or brazing rod into the area to be repaired. At the same time, the welder is melting the parent metal so that the two metals flow together and integrally bond to each other. Such welding requires a great deal of expertise in recognizing color changes, and the welder must know how to control the heat emitted from various areas of the torch flame. Such expertise comes only after years of training and practice under the supervision of a master welder. The cylinder block is then cooled at a very slow and controlled rate until it is cool enough to be machined. The heating and cooling processes remove the built-in stresses that occurred when the block was originally cast at the foundry. This relaxation of stresses causes distortion on the cylinder block. For this reason, every block we weld we also completely remachine. All deck surfaces are milled and the counterbores are recut to factory specifications. Cylinders are all bored to the next oversize and liners are hone fitted. The main journal caps are checked for tightness and replaced if loose. New style stabilizers are installed and the block is realign bored. Balance shaft and camshaft journals are checked for correct sizes and alignment. These cylinder blocks are thoroughly tested, cleaned, and inspected before leaving our shop. They come back to you looking new and, in our consideration, they perform better than new blocks. The methods we use allow us to salvage about 90% of damaged cylinder blocks. The number of companies having a good reputation for cylinder block repair is very small. All of these companies utilize the gas fusion process as their basic repair. They also use a variety of different repairs, depending on the nature and location of the repair needed. We have an excellent reputation for our cylinder block repair and we are looking forward to doing business with you.
