Claim:
A tensioner that is adapted to be coupled to an engine for tensioning an endless power transmitting element, the tensioner comprising: a front plate having a bent tab that is configured to locate the tensioner relative to the engine; a base defining a bore and a pair of tool slots, the bore being formed along a first axis and having a first abutment surface, the first abutment surface being centered about the first axis and extending in a circumferential direction, the base being coupled to the front plate such that the front plate closes the bore, the tool slots being formed through the base on a side opposite the front plate and intersecting the bore; a pivot arm disposed within the bore for rotation relative to the base, the pivot arm having a second abutment surface and a first tooling feature, the second abutment surface abutting the first abutment surface and extending in a circumferential direction; a spring biasing the pivot arm about the base in a tensioning direction; and a push rod mounted to the pivot arm for pivotal movement about a second axis that is offset from the first axis, the push rod having a second tooling feature; wherein the first and second tooling features can be aligned to the tool slots through rotation of the pivot arm relative to the base to permit a tool to be inserted through the tool slots and engaged to the first and second tooling features.
