Section II. SERVICE AND INSPECTION
7-2. GENERAL MAINTENANCE INSTRUCTIONS
a.
Maintenance. Follow these basic instructions when working on the transmission.
(1)
Handle transmission parts carefully to prevent nicking, scratching, or denting. Some parts rely upon a
smooth surface to create a seal. They may leak if surfaces are scratched.
(2)
Do not use metal tools when removing gaskets or packing. Use a pointed wooden dowel to remove
packing from grooves. Use wooden or plastic scrapers on gasket surfaces.
b.
Cleaning. Follow these cleaning instructions when working on the transmission.
(1)
All parts must be clean to permit proper inspection of subassemblies and parts. Ensure that no debris or
foreign material enters the transmission.
