7) Cautions in Disassembling and
Assembling Components
(1)
Secure outboard motor to dedicated stand firmly.
(2)
Take special care not to scratch painted surface or mating
surfaces of cylinder and crankcase.
(3)
Replace unreusable parts such as packings, gaskets, O
rings, oil seals, spring pins or split pins with new ones after
they were 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 tools that are specified, 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. Refer to
applicable parts list.
(7)
Clean individual parts that have been removed, and check
their condition.
(8)
When reassembling parts, take sufficient care also for details
such as fit, repair limits, air tightness, cleanliness of oil holes
for lubrication and greasing, packings, wirings and piping.
For components using many bolts and nuts for assembling,
such as cylinder head and crankcase, tighten all the
fasteners evenly to their specified torque clockwise in two or
three stages, inner ones first and then outer ones. (Reverse
the order when disassembling.)
(9)
When installing bearings, bring the flat (numbered) side of
the component to the special assembling 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 orientation. Apply recommended grease to the lip
before installation.
(11) When applying liquid packing, take sufficient care of the
thickness and quantity. Excessive application may ooze out,
adversely affecting interior of the crankcase. Use adhesive
after thoroughly reading the instructions.
(12) When servicing power unit, use of wooden work board
makes the work easier.
