PREPARATION FOR REMOVAL
PROCEDURES
1.Remove all dirt, mud, dust and foreign
material before removal and disassembly.
2.Use proper tools and cleaning equipment.
Refer to the "SPECIAL TOOLS" section.
3.When disassembling the machine, always
keep mated parts together. This includes
gears, cylinder, piston and other parts that
have been "mated" through normal wear.
Mated parts must always be reused or
replaced as an assembly.
4.During machine disassembly, clean all
parts and place them in trays in the order
of disassembly. This will speed up assem-
bly and allow for the correct installation of
all parts.
5.Keep all parts away from any source of
fire.
