Patent ID: 7752727

Claim:
A gear holding device for holding a gear of an engine stationary relative to another part of the engine, said device comprising: a body having an upper end and a lower end, and a threaded passage extending between the ends; a projection extending laterally of the body and adapted to engage one or more teeth of the gear such that there is substantially no engagement of the body with the gear, wherein the projection is substantially in the shape of a half cylinder and a longitudinal axis of the cylinder extends parallel with an axis of the body; a hooked portion extending from the lower end of the body and being immovable relative to the body when engaging the gear, wherein said hooked portion is adapted to (i) extend between the gear and the other part of the engine, and (ii) hook behind the teeth of the gear; and a jacking screw extending through the passage and rotatable relative to the body such that an end of the jacking screw engages the other part of the engine, wherein rotation of the jacking screw alone moves the hooked portion into engagement with the gear to hold the gear relative to the other part of the engine, wherein the body, the hooked portion and the projection are of unitary construction.
