  • Patent number: 5013076
    Abstract: A removable, reuseable holding jig for a locking plate associated with the end cap of a railroad truck bearing in which the locking plate provides a plurality of cap screw head apertures through which the end cap holding screws project when threaded into the axle end cap of the railroad bearing. The holding jig is of the same configuration of such locking plate but of a larger size so as to overlap the edges of such plate and to be confined in the well provided by the axle roller bearings. The holding jig will position, and by a series of lugs engage the sides of the locking plate so as to prevent rotational movement thereof resulting from the rotational torque of the cap screws as they are threaded into the axle bearing.
