SPT - Canon FTb service

Comprehensive service manual for the Canon FTb, a pre-A series SLR and the repair standard for professional technicians. This workshop documentation provides step-by-step procedures for disassembly, adjustment, and troubleshooting of all major mechanisms. Adjustment locations are identified by letter codes A through P, covering low-light meter cell alignment, metering limits indicator calibration, mirror-lifting mechanism engagement, and shutter speed governor settings. Separate sections detail shutter speed adjustments across the 1/125 to 1/1000 second range and the 1/30 to 1/8 second range, with precise curtain travel specifications and mirror-lift timing verification. The exposure meter linkage section explains gear engagement positioning and synchronization mark alignment—both critical for accurate light metering. Essential reference data includes flange-focal distance specifications, precise curtain travel measurements in millimeters, and complete disassembly and reassembly sequences with visual reference points throughout. A dedicated troubleshooting guide addresses erratic curtain movement, meter malfunction across varying light conditions, diaphragm blade sticking, release button sluggishness, and mirror-up mechanism faults. Technical specifications are supported by multiple photographic illustrations showing internal assemblies, mechanical relationships, and correct positioning of springs, cams, and shim locations necessary for proper camera function and repeatability.
