Camshaft geometry is the heart of how an engine runs. Regulating three major events: WHEN the valves open (valve timing), HOW MUCH the valves open (lift), and HOW LONG the valves are open for (duration). Here at Associated Fuel Systems we put each camshaft through a detailed inspection and polishing process to ensure they meet the proper O.E. standards.
Associated Fuel Systems Inc., has the ability to recondition connecting rods with the finest equipment available. From using our Sunnen Rod Hones to magnaflux and inspect each rod, to our Sunnen rod boring machine to precisely machine center to center dimensions our recognized standard procedures are graded an A+ in accurate re-sizing of your connecting rods every time.
AFS has invested itself to having one of the finest crankshaft departments around. With large Peterson grinders, we can grind any crankshaft up to 14 feet in length. Polishing is done with variable speed polishers and special abrasives that allow us to put the proper finish on the crankshafts. Our crankshafts meet the tightest reconditioning specifications that the industry brings. Getting the backbone of your engine back to it’s original geometry with our proven methods is no problem. If it’s complex finish grinding of prototype crankshafts to diesel stroke modification and counterweighting, we are equipped to handle your most difficult tasks. Associated Fuel Systems Inc., has the precise tooling and experienced technicians to perform crankshaft repair in-house.
Our Cylinder block department is efficient and accurate. With our three large automatic Berco machines we have the ability to machine blocks 12 feet in length. This equipment, along with close attention to detail makes this department one of the most compelling and effective in the industry.
Associated Fuel Systems, Inc. uses the latest tooling which enables precise surface finishes and sizing. Our head department is equipped to machine all manufacturers of diesel and natural gas cylinder heads. Our capacity is from small heads all the way up to the giant CAT 3600 series head which approaches 500 lbs. and has a seat diameter of over 4 inches. One of the added benefits of our seat and guide tooling is that we can vacuum test the finished product prior to assembly, a process that ensures quality and saves time. Being built around two key pieces of equipment: the Serdi 100 and a Peterson surfacer our head department is set up perfectly for production and accuracy. The Serdi 100 seat and guide machine can cut all three seats in one pass while maintaining concentricity of .002″. This provides an excellent seat for the valves to seal against. The Peterson uses CBN technology and produces exact roughness (Ra) consistently across the surface of the cylinder head.
AFS has a Sunnen HC1DP honing machine for finishing cylinders. Using Flex-Honing Tool procedures allows us to improve and do away with rough, torn, and folded metal caused by wear or prior machining. Coated with abrasive globules the flexible nylon strands adjust to an engines cylinder’s surface to create a flat, smooth, cross-hatch surface. Plateau hones allow this process to minimize ring fatigue at jumpstart, also limit oil consumption and provide a stable finish. We use the best to get the best results.
