Ford Super Duty 7.3L Clutch Pedal Assembly YC3Z-7B633-BA

This is a complete clutch pedal assembly for the 1999-2003 Ford Super Duty with the 7.3L Power Stroke and the manual transmission, which on these trucks is the ZF S6-650 6-speed. It replaces OE YC3Z-7B633-BA and YC3Z7B633BA. Listed fitment is the F-250, F-350, F-450 and F-550 Super Duty 7.3L from 1999 through 2003. It comes as the pedal arm, cast mounting bracket, over-center assist spring and rubber pedal pad, plus 2 screws and 2 washers.

On high-mileage diesel trucks the pivot bushings in the pedal bracket wear out and the heavy clutch spring loads the bracket every time the pedal goes down. The usual signs are a pedal that wobbles side to side, clunks or squeaks, does not return fully, or has the clutch engaging at a different point than it used to. Replacing the full assembly takes care of the worn pivot, the spring and the bracket at once instead of trying to press new bushings into a worn bore.

To swap it, disconnect the battery, unhook the clutch master cylinder pushrod from the pedal arm, unplug the clutch pedal switches, then remove the bracket fasteners under the dash and pull the old assembly out. Install the new one, reconnect the pushrod and switches, and check that the truck will only crank with the pedal down and that the clutch fully releases before driving it.
