Figure 43: Slack removed by retracting
15.Refit the straight support guide to the front friction retaining plate.
16.Now slacken the middle roller until it is just touching the rod. Use the
manual inverter to THRUST the rod through the base plate hole
increasing the roller tension as the rod moves. Keep increasing the
tension until the rod stops bending to the right (looking facing the
thruster mechanism side) if it bends to the left then remove some of the
tension as the rod is being over straightened. This may take two or
three attempts. If needed the straightener position can be adjusted to
get the rod in the center of the base plate hole.
17.Refit the cone as stated in the cone removal section.
Maintenance
NOTE: Appropriate safe working practices should be followed to
ensure that all hazards are minimised.
When the system is in operation, the cone-rod should be washed down with
clean, salt-free water whenever it is returned to the deck of the ship. This will
reduce corrosion and abrasion to the cone-rod and drum, and enable thorough
inspection of the cone-rod, connectors, and connecting cables.
The electrical cable connected to the cone-rod in the back of the drum should
be visually inspected to ensure there are no chafes or cut in the insulation.
The connectors on both ends of the cable should be tightly fitted with no face
gap, and the lock-rings should be finger-tight. Any damaged cables should be
replaced immediately.
