7) Cautions in Disassembling and
Assembling Components
(1)
Secure outboard motor to a dedicated stand.
(2)
Replace parts that cannot be reused such as packings,
gaskets, O-rings, oil seals, spring pins or split pins with new
ones after disassembly. Replace deformed snap rings with
new ones.
(3)
Replace parts such as packings, gaskets, O rings, oil seals,
spring pins or split pins with new ones after they are
removed. Replace deformed snap rings with new ones.
(4)
When replacing parts, be sure to use genuine parts. For
fluids such as gear oil, use genuine product.
(5)
Be sure to use special service tools, and perform the work
properly.
(6)
When reassembling parts, use their mating marks. For parts
without mating marks, simple marking makes reassembling
easier. Use applicable parts list for reference.
(7)
Clean individual parts that have been removed, and check
their condition.
(8)
When reassembling parts, pay extra attention to details such
as the fitting of each part, repair limits, air tightness, clogging
of oil holes for lubrication and greasing, packings, wiring,
piping and so on. For components which use a lot of bolts
and nuts for assembly, such as the cylinder head and
crankcase, tighten all the fasteners uniformly to their
specified torques clockwise in two or three stages, starting
with the inner ones first followed by the outer ones.
(Reverse the order when disassembling.)
(9)
When installing bearings, the flat (numbered) side should be
the side in contact with the special assembly tool.
(10) When installing oil seals, be careful not to scratch the
surface of the lip that contacts with the shaft, and install
them in correct direction. Apply recommended grease to the
lip before installation.
(11) When applying liquid packing, be extra careful of the
thickness and quantity. Excess liquid may ooze out if too
much liquid is applied, adversely affecting the interior of the
crankcase. Use adhesives after thoroughly reading the
instructions.
(12) When servicing power unit, use of wood work board makes
the work easier.
