ABSTRACT:
Gears with a soft metal hub and a hexagonal coaxial hole in the hub, often need repair. Accordingly the old hub is removed and a new solid plug is pressed in place and welded. A radial face on the plug and the gear are flush. A lock plate is placed on this radial face and wleded along an arc. Then the assembly has an axial circular hole bored therethrough and then a hexagonal hole is broached therein. The lock plate has two ears opposite the weld which receive a bolt.
