For the Spicer double plate clutch with a non-synchronized transmission, the correct pedal height where the throw-out bearing contacts the clutch brake is

• A. 2 inches
• B. 3 inches
• C. 4 inches
• D. 5 inches

Answer: (C)

The point being tested is when the throw-out bearing is positioned to contact the clutch brake in a Spicer double-plate clutch with a non-synchronized transmission. That brake action is designed to slow the flywheel/input shaft to help you mesh gears smoothly during a shift. The pedal height at which this contact occurs is fixed by the linkage geometry and the brake’s location on the flywheel. Four inches is the mid-travel position where the bearing meets the clutch brake at the correct moment: late enough that the clutch is not fully released yet, but early enough to impart the brake action as you begin to disengage. This timing helps prevent gear clash and reduces shock loads on the gears during shifts. If you only travel two or three inches, the brake contact would be premature or unlikely to occur in time for a smooth shift; if you go toward five inches, the brake would stay engaged longer, causing unnecessary engine drag and wear.
