Abstract
A method for locating an injector ball valve guide in alignment with a valve seat mounted in a common recess of an injector valve body. The valve guide is a disk that has a central opening which guides a valve ball of an associated valve member. During assembly, the guide disk is aligned with the valve seat by a locating tool having an oversized ball on a load rod. The oversized ball is fitted closely within the central opening of the guide and is seated on the ball seat to align the seat and opening. The valve seat and guide disk are then locked in the recess by crimping edges of the recess against the valve seat. The locating tool is removed and assembly of the remaining injector components is completed. The method simplifies alignment of the seat and guide components. In a variation of the method, the guide is aligned with and fixed to the valve seat with the oversized ball in place to form an aligned subassembly for subsequent installation into a fuel injector.
