Section VII. GENERAL MAINTENANCE
This section includes brief descriptions for repairs which are al-
located to direct support and general support maintenance which
would otherwise be repeated several times throughout the chapters.
Before removal or disassembly of a component, inspect the overall
condition and note all symptoms of faulty operation. This helps de-
termine causes of failure of faulty operation, and facilitates repair.
Provide a clean place to work, facilities for cleaning the engine,
compressor, welder, and shop body parts and overhaul stand.
Standard engine overhaul shop tools and resurfacing equipment are
necessary. These tools save time and insure good workmanship.
Engine components and parts are overhauled in one of the following
Lubrication System, Cooling System, Fuel System, Air
Supply, Exhaust Systems, Electrical System, and Engine. Components
and parts will be removed as necessary. Note any precautions and
Check all wiring for cracks and frayed places. Pay particular at-
tention to places where wires pass through holes in the frame or
over sharp metal edges.
Solder all terminal connections to insure good electrical contact.
Test electrical leads for continuity. Disconnect each end of the wire
from the components. to which it is connected.
GENERAL METHODS USED TO ATTAIN PROPER SUPPRESSION.
Essentially, suppression is attained by providing a low resistance path
to ground for the stray currents. The methods used include shielding
the ignition and high-frequency wires, grounding the frame with
bonding straps, and using capacitors and resistors.
INTERFERENCE SUPPRESSION COMPONENTS.
Primary Suppression Components. The primary suppression compo-
nents are those whose primary function is to suppress radio interfer-
ence. These components are described and located in figure 4-12.
Secondary Suppression Components. These components have radio
interference suppression functions which are incidental or secondary
to their primary function.
