Abstract
A method of rebuilding fuel injection pumps which have become inoperative due to excessive wear or other damage. Damaged surfaces of parts of the fuel distribution assembly, e.g., head and rotor assemblies used in rotary distributor type diesel fuel injection pumps, as well as plunger and barrel assemblies of inline diesel injection distributor pumps, are restored by a method involving disassembling of the distributor assemblies, inspecting and categorizing of damaged surface areas, machining of the parts to return them to their proper degree of roundness and surface finish with selected areas of the rotor or plunger being plated with a hard material such as chrome.
