It has a longitudinally slidable adaptor for pressing down the valve spring and openings for access to the collets.
Claims8
A portable hand tool for facilitating the removal or mounting of valve springs of overhead valve internal combustion engines, comprising a hand lever apertured at one end to receive an upstanding bolt or stud on the cylinder head such that the end of the lever can be held down by a screw threaded member on the bolt or stud and yet the lever can be pivoted at least over a limited arc, in a vertical plane about the connection to the bolt or stud, the lever having a rail in its intermediate section, and an adaptor loosely mounted for free longitudinal sliding movement along the rail and for limited pivotal movement with respect to the rail, the adaptor having a downwardly facing opening for receiving the upper end of a valve stem while the lower side of the adaptor is stably pressing against a retaining collar for the upper end of the valve spring, the adaptor also being arranged to give lateral access to collets or other means for holding the spring against upward movement relative to the valve stem when such means are released by compression of the spring by the lever.
A hand tool for remounting or removing valve springs of overhead valve internal combustion engines comprising:
- an elongated lever having an aperture at one end for receiving an upstanding bolt on an engine;
- a handle on the opposite end of said lever from said aperture, said handle being offset from said lever generally parallel to the longitudinal axis of said aperture;
- and, an adaptor having a downwardly facing opening for receiving the upper end of a valve stem while the lower surface of the adaptor is pressing against a retaining collar for the upper end of the valve spring, said adaptor being loosely mounted on said lever for free sliding movement therealong between said handle and aperture and for limited pivotal movement relative thereto, said adaptor extending outwardly from said lever in a direction generally opposite from the offset direction of said handle.
