Abstract
A kit of tooling components for facilitating removal of a gear from a shaft includes a plurality of jaw members that are adapted to fit through blanking holes defined in the gear. The jaw members are further adapted to engage the gear. The kit further includes a set of studs with each of the studs adapted to engage one of the jaw members and a plate adapted to couple to the studs. The kit further includes a jack adapted to engage and fit between the plate and the shaft. Included as a part of this disclosure is a method of removing a camshaft gear by use of the kit of tooling components.
