Safety while working
Handling of sealant
• Wear protective gloves to protect your skin,
when using the sealants.
• See the material safety data sheet issued
by the manufacturer. Some of the sealants
may be harmful to human health.
Special service tool
Use the recommended special service tools
to work safely, and to protect parts from dam-
age.
Tightening torque
When tightening nuts, bolts, and screws, fol-
low the tightening instructions provided
throughout the manual. If the tightening order
is not specified, tighten the large sizes first,
and then tighten the small sizes, starting from
the center and moving outward.
Non-reusable part
Always use new gaskets, seals, O-rings, cot-
ter pins, and so on, when installing or assem-
bling parts.
Disassembly and assembly
• Use compressed air to remove dust and dirt
during disassembly.
• Apply engine oil to the contact surfaces of
moving parts before assembly.
• Install bearings so that the bearing identifi-
cation mark is facing in the direction indi-
cated in the installation procedure. In
addition, make sure to lubricate the bear-
ings liberally.
• Apply a thin coat of water resistant grease
to the lip and periphery of an oil seal before
installation.
• Check that moving parts operate normally
after assembly.
