Abstract
An apparatus is used to align, burnish, and secure an upper needle guide for a fuel injector valve body. The apparatus includes a lower portion having a fixture containing a spring-loaded plunger and a spring-loaded centering pin, and an upper portion having a burnishing tool, a spring-loaded stripper, and a crimping ram. The fixture aligns the needle guide and the valve body, and as the two portions are operated closed, the inside diameter of the upper needle guide is first burnished, and then the valve body is crimped onto the needle guide. The stripper holds the crimped parts against the lower portion of the apparatus while the upper and lower portions are operated open to withdraw the burnishing tool from the inside diameter of the needle guide.
