SPT - Leica CL Guide

Comprehensive service manual for the Leica CL rangefinder camera, covering maintenance, adjustments, and systematic troubleshooting for this classic model. The guide walks through detailed disassembly procedures with step-by-step photographic illustrations, making internal component access straightforward and verifiable at each stage.

Adjustment locations are thoroughly documented—shutter-speed alignment, rangefinder calibration (both horizontal and vertical shifts), secondary-image focus compensation, meter housing movement, and fast-speed control—with each adjustment cross-referenced to specific component identifiers. Technical specifications include the flange-focal distance of 27.95 mm, battery test values at ASA 100 with 1/60 reference, and precise curtain-travel timing parameters essential for accurate shutter performance.

The disassembly sequence section establishes the correct removal order for major assemblies: back shell, bottom cover, top cover, pressure-plate assembly, front plate, speed-knob assembly, rangefinder control arm, and photocell unit. Critical handling notes alert technicians to fragile elements—particularly the meter needle—where careless handling causes permanent damage.

Electrical troubleshooting data includes CdS cell resistance specifications (280 ohms) and galvanometer coil resistance (3.8K ohms), allowing rapid diagnosis of metering circuit faults. Complete wiring diagrams and annotated positional schematics enable quick location and identification of every internal component, making this repair manual an essential reference for service technicians and experienced camera restorers working on this precision instrument.
