Section I. INTRODUCTION

B-1. GENERAL

This appendix provides a summary of the maintenance operations for the Disk Unit. It authorizes categories of

maintenance for specific maintenance functions on repairable items and components and the tools and equipment

required to perform each function. This appendix may be used as an aid in planning maintenance operations.

B-2. MAINTENANCE FUNCTION

Maintenance functions will be limited to and defined as follows:

a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical

characteristics with established standards through examination.

b. Test. To verify serviceability and to detect incipient failure by measuring the mechanical or electrical characteristics

of an item and comparing those characteristics with prescribed standards.

c. Service. Operations required periodically to keep an item in proper operating condition, i.e., to clean

(decontaminate), to preserve, to drain, to paint, or to replenish fuel, lubricants, hydraulic fluids, or compressed air

supplies.

d. Adjust. To maintain, within prescribed limits, by bringing into proper or exact position, or setting the operating

characteristics to the specified parameters.

e. Align. To adjust specified variable elements of an item to bring about optimum or desired performance.

f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test measuring and

diagnostic equipments used in precision measurement. Consists of comparisons of two instruments, one of which is a

certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being

compared.

g. Install. The act of emplacing, seating, or fixing into position an item, part, module (component or assembly) for an

unserviceable counterpart.

h. Replace. The act of substituting a serviceable like type part, subassembly, or module (component or assembly) for

an unserviceable counterpart.

I. Repair. The application of maintenance services (inspect, test, service, adjust, align, calibrate, replace) or other

maintenance actions (welding, grinding, riveting, straightening, facing, remachining, or resurfacing) to restore
