IMPORTANT INFORMATION
PREPARATION FOR REMOVAL AND
DISASSEMBLY
1. Before removal and disassembly,
remove all dirt, mud, dust, and foreign
material.
2. Use only the proper tools and cleaning
equipment.
Refer to “SPECIAL TOOLS”.
3. When disassembling, always keep
mated parts together. This includes
gears, cylinders, pistons and other parts
that have been “mated” through normal
wear. Mated parts must always be
reused or replaced as an assembly.
4. During disassembly, clean all of the
parts and place them in trays in the
order of disassembly. This will speed up
assembly and allow for the correct
installation of all parts.
5. Keep all parts away from any source of
fire.

and appearance, but inferior in quality.
