FACTORY WORKSHOP SPECIFICATION:

Critical Recall Safety Countermeasure

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL COUNTERMEASURE (Recall 25V-146 / Bulletin MC25-04). Original release lever arms suffered fatigue fracture at the shaft weld joint, disabling clutch disengagement. The countermeasure shaft features reinforced metallurgy and stress-relieved weld penetration.
