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 “SPECIAL TOOLS” on page 1-17.
3. When disassembling, always keep mated
parts together. This includes gears, cylinders,
pistons and other parts that have been “mat-
ed” through normal wear. Mated parts must
always be reused or replaced as an assem-
bly.
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.
