FUJICA - Fuji GS645 GS645WIDE GS645S Service Manual

Complete service manual for the FUJICA GS645, GS645-WIDE, and GS645-S medium-format cameras. This workshop reference covers full disassembly and reassembly procedures alongside detailed adjustment instructions for every critical mechanism—an essential technical resource for repair specialists and service technicians working on these folding rangefinder models.

The manual divides into four functional sections. The first addresses disassembly and reassembly of major subassemblies: top cover, rangefinder block, film advance mechanism, body housing, and front cover linkage. The second section walks through specialized reassembly sequences and calibration work—film take-up shaft friction tuning, bellows discharge groove clearance, front cover mechanism parallelism, shutter timing, infinity focus correction, viewfinder coincidence alignment, film advance and shutter charge synchronization, shutter release lock behavior, front cover linkage binding, and electrical circuit calibration.

Every procedure is illustrated with technical diagrams and precise part reference numbers throughout. The third section specifies specialized service tools needed for the work. The fourth section provides a complete parts catalog with corresponding reference designations for every component. With exploded assembly views and sequential step-by-step photography, this manual equips technicians with the depth needed to execute accurate repairs and full mechanical restoration on these precision medium-format instruments.
