1-48. GENERAL MAINTENANCE INFORMATION.
This section contains general information and practices that maintenance personnel will become familiar
with before attempting work on the engine. Refer to Appendix G for torque values for bolts, nuts, and
connectors used on the engine.
1-49. General Maintenance Practices.
Engines removed for unscheduled repair, require only that work necessary to return the engine to service.
During disassembly, examine all parts and assemblies for serviceability. Look for indications of work
done incorrectly during previous maintenance or overhaul. Report any such indications.
Prolonged contact with lubricating oil (item 5, Appendix D) may cause a skin
rash. Those areas of skin and clothing that come in contact with lubricating
oil should be thoroughly washed immediately. Areas in which lubricating oil
is used should be adequately ventilated to keep mist and fumes to a minimum.
Never allow fuel or oil to contact electrical connectors. Do not use pliers to
tighten connectors. Use only specified solvent to clean connectors. Other
solvents might damage connectors.
NOTE
Lubricating oil may soften paint upon contact. If lubricating oil is spilled on
painted surfaces, these surfaces should be thoroughly washed.
