When the retraction tank is made locally, finish it so
that the welding bead does not protrude on the inner
surface of the tank. The tank guide will hit the bead,
causing motor born-out. The gap between the tank
and tank guide is 1 mm. Also when installing the
tank, orient the welding bead so it faces the port or
starboard direction.
