The 1967 Ford Mustang was equipped with either a 200-cubic inch, six-cylinder engine or with a 260-, 289- or 390-cubic inch eight-cylinder engine. Each engine features a single pulley at the bottom of the front of the engine. The purpose of the pulley is to provide a means by which the engine's belt-driven components can operate. A rubber belt is used to connect the component to the pulley. If the pulley becomes damaged, it could break under the stress of the power produced by the engine. Fortunately, replacing a damaged pulley is a fairly straightforward job.
Tools Used: Wrench, Deep-set socket wrench, Socket extension, Torque wrench
Replace Pulley
Slacken the pulley's belt by loosening either the alternator or, if equipped, the power-steering pump. The alternator and power-steering pump are both secured with two bolts. Loosen either component's bolts with a wrench and rotate the component toward the engine block to slacken its belt. If equipped with both components, loosen each component's retaining bolts to slacken both belts.
Pull the belt(s) off of the bottom of the pulley.
Remove the three securing bolts from the center of the pulley with a deep-set socket wrench and a socket extension.
Pull the pulley off of the vibration dampener.
Position the replacement pulley against the front of the vibration dampener, ensuring that the pulley's three bolt holes align with the bolt holes on the vibration dampener.
Install and tighten each of the pulley's three securing bolts to between 70 and 90 foot-pounds of torque with a torque wrench.
Position the pulley's belt(s) into the grove(s) of the pulley.
Pull the alternator and, if so equipped, the power-steering pump away from the engine to tighten the belt(s).
Tighten the alternator and the power-steering pump's retaining bolts with a wrench.
