7) Cautions in Disassembling and
Assembling Components
(1) Secure outboard motor to dedicated stand firmly.
(2) Take special care not to scratch painted surfaces or
mating surfaces of cylinder and crankcase.
(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 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.
(7) Clean individual parts that have been removed, and check
their condition.
(8) When assembling, be careful of the fit, repair limits, air-
tightness, clogging of oil holes for oil feeding or greasing,
packings, wirings, pipings and other detailed parts. For the
components that use many bolts and nuts such as cylinder
head or crank case, tighten the fasteners in the order
shown by the numbers to prevent uneven tightening. If the
numbers are not shown, tighten the fastners in diagonal or
clockwise order from inner ones to outer ones evenly to
specified torque. In either case, tighten the fastners to the
specified torque in two or three steps. (Reverse the order
when disassembling.)
(9) When installing bearings, face the flat (numbered) side 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 sealant, take care to use sparingly.
Excessive application may be oozed 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.
