Abstract

PURPOSE: To operate the work of processing a plunger barrel under the condition with the same stress applied as in a state of normal use, with a dummy delivery valve guard screwed into the injection pump.
CONSTITUTION: Prior to the work of processing a hole 16 of plunger barrel, a dummy delivery valve guard 15, which provides the same external shape as a condition with delivery valve guard and delivery valve guide installed further provides a penetration hole in the center portion of inside diameter D1 slightly larger than inside diameter D2 of the plunger barrel hole 16, is installed by method of screw-in of a screw installed to its periphery. Though a main unit 1 generates a deformation by this tightening force, under this condition the work of drilling and grinding the plunger barrel hole is operated through the penetration hole 17. Therefore, the plunger barrel hole becomes correctly round when in use.
