CHAPTER 3

DISASSEMBLY Section I. CAMERA BODY

3-1. General

In so far as possible the cause of the malfunctions should be identified before disassembling the camera. Seldom must a camera be completely taken apart for repair. Disassembly should not be carried further than is necessary to correct the determined malfunction. To do so will disturb other adjustments. The identity, location and position of all parts should be noted as they are removed, and replaced in the same position when reassembling. Many parts are not directly interchangeable but must be fitted individually. All subassemblies can be taken apart, but in many cases it is advisable to replace the entire subassembly rather than to attempt to repair it. An example is the range-viewfinder assembly. This is an intricate mechanism and, if taken apart, would require the use of special collimators for realignment. Components which are riveted, sweated or press fitted should be replaced as assemblies. This is especially true of optical elements which are cemented.
