Abstract:
An installation tool installs a camshaft to a lower supporting portion. A cylinder head of an internal combustion engine includes the lower supporting portion, a cam holder, and a half-thrust washer. The camshaft is sandwiched between the cam holder and the lower supporting portion via a bearing. The half-thrust washer is inserted into respective annular groove disposed in an outer peripheral surface of the bearing and half annular groove disposed in the cam holder. The installation tool includes a bearing holder that holds the bearing, a head abutting portion abutted against a reference surface of the lower supporting portion with the bearing held, and an opposed concave knock portion into which a knock collar disposed in the cam holder is inserted to adjust a position of the half annular groove with respect to the half-thrust washer.
