<p>The valve locks (32, 34) include an inwardly extending ridge (40)that engages a circumferential groove (44) that extends around an end portion (42) of the valve stem (20). The valve lock is retained in this position by a tapered central bore (46) of the valve spring retainer (30) that produces an inward clamping force on the valve lock. The tool includes a plunger (66) having a diameter equal to the diameter of the valve stem. The user positions the valve locks on the protruding cylindrical surface (72) of the plunger, where they are held by magnetic attraction. The user pushes the end (52) of tool against the valve spring retainer, thereby compressing the valve spring so that the valve stem pushes the plunger into a close-fitting loader end cap (60) until the valve locks are transferred to the valve stem and into engagement with the circumferential groove.</p> |
