APPLICABLE MODEL(S)VINS
2006-2007 MX-5 vehicles with VINS lower than JM1 NC 136430
(produced before March 1, 2007)

DESCRIPTION

Some vehicles may experience that the free play on the clutch pedal increases and the clutch is hard to disengage.

At hot ambient temperatures or approx. 85°F (30°C), ethanol used during installation of the clutch release cylinder boot becomes vaporized and expands. As the pressure in the boots increases, the piston is pushed back into the release cylinder body. As a result, a gap appears between the piston and the push rod, resulting in excessive free play and the clutch hard to disengage.

As a mass production change, ethanol is no longer used during clutch release cylinder assembly. Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Verify customer concern.

2. Replace the clutch release cylinder. Refer to Workshop Manual section 05-10 - CLUTCH RELEASE CYLINDER REMOVAL/INSTALLATION.

3. Bleed the clutch release cylinder. Refer to Workshop Manual section 05-10 - CLUTCH FLUID REPLACEMENT.

4. Verify repair.
