Rolleiflex SL-66 Stuck Mirror Repair Manual

Comprehensive technical guide for diagnosing and repairing common malfunctions on the Rolleiflex SL66, particularly focusing on stuck mirror in raised position and jammed winding lever. This manual, authored by Philippe Raybaudi, addresses the root causes of failures stemming from lubricant deterioration and hardened grease accumulation over time. The guide presents a systematic approach to disassembly and unlocking procedures, emphasizing the importance of general overhaul (CLA: clean, lubricate, and adjust) every five years. Detailed instructions cover the removal of the camera cover, identification of the five screws on the winding button side, and access to critical mirror and curtain shutter mechanisms. Special attention is given to the second curtain spring, which frequently disengages and causes the mirror to jam against the viewfinder glass. The manual includes detailed photographs documenting component locations, mechanism conditions before and after intervention, and specific areas requiring careful re-lubrication. Practical recommendations for using varnish to secure certain screws supplement the technical procedures. The document strongly emphasizes the necessity of acquiring minimum required knowledge and avoiding inappropriate products such as WD40 that could permanently damage the camera.
