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 equip-
ment.
Refer to the “SPECIAL TOOLS”.
3.When disassembling, always keep mated parts
together. This includes gears, cylinders, pis-
tons and other parts that have been “mated”
through normal wear. Mated parts must al-
ways be reused or replaced as an assembly.
4.During disassembly, clean all of the parts and
place them in trays in the order of disassem-
bly. This will speed up assembly and allow for
the correct installation of all parts.
5.Keep all parts away from any source of fire.
