TRIM/TILT
Make sure that there is no washer, etc. on the magnet
in the yoke [1].
Wrap the armature shaft [2] with a shop towel [3] or
equivalent material, and hold the shaft with pliers [4].
Pulling the two motor wires [5] of the yoke side slowly,
install the armature/front bracket [6] on the yoke.
If it is hard to install the armature/front bracket in the
yoke, check whether the metal of the yoke (i.e. where
the armature shaft is installed) is out of position and
repeat.
After installation, check that the armature turns
smoothly and tighten the two screws (4 x 16 mm) [7].
After tightening the two screws, connect the battery to
the power tilt motor 2P connector and check whether
the motor turns (page 19-41). If the motor does not turn,
disassemble the power tilt motor again, and check
whether the motor wire (Blue wire) terminal is
disconnected.
Install the two grommets [1] and wire holder [2] on the
yoke [3].
Tighten the screw (stainless steel screw: 4 x 16 mm) [4]
to the specified torque. Do not overtighten it.
TORQUE: 1.4 N·m (0.14 kgf·m, 1.0 lbf·ft)
Tape the corrugated teflon tube [1] with heat resisting
tape [2] so that the distance from the wire holder end to
the tube end is 30 mm (1.2 in) or less [3] as shown.
Bleed air from the power trim/tilt without mounting on
the outboard motor (page 19-31).
