Abstract:
A method for seating a valve lock into a circumferential groove located adjacent an end of a cylindrical valve stem, comprising the steps of:a) providing a cylindrical plunger having the same diameter as the cylindrical valve stem; b) inserting the plunger into a bore that extends through a loader end cap, the diameter of the bore permitting the loader end cap to slide in a loose sliding fit along the plunger and along the valve stem; c) slidably adjusting the plunger within the loader end cap until an end portion of the plunger protrudes out of the loader end cap; d) placing the valve lock onto the cylindrical surface of the protruding end portion of the plunger; e) holding the end of the plunger against the end of the valve stem with the plunger aligned with the valve stem; f) while holding the plunger in end-to-end relation with the valve stem, advancing the loader end cap toward the valve stem so that the advancing loader end cap pushes the valve lock along the plunger then onto the valve stem and along the valve stem until the valve lock seats in the circumferential groove.
