Pedal freeplay should be 3/4 - 1 1/8" (1966), 1 - 1 1/2" (1967), 1 1/8 - 1 3/4" (1968-72), or 3/4 - 1 5/16" (1973). To adjust, disconnect spring between cross shaft lever and clutch fork and loosen push rod lock nut approximately three turns (until free of clutch fork). Hold clutch fork rearward and adjust rod length until it touches its seat in fork. Adjust lock nut to obtain about 3/16" clearance between nut and rod sleeve end. Pedal freeplay should be as specified. On later models there is a gauge hole in lever (upper hole). Disconnect return spring at clutch fork. Install push rod or swivel in gauge hole and increase length until all lash is removed from system. Reinstall rod in lower hole, being careful not to change rod length. Pedal freeplay should be as specified.
