Close sea cock before starting work. Drain the water from the seawater system.
Replace the anode if more than 50% of it has been used. When fitting, ensure that
there is good metallic contact between the anode and the material.
Check all connections and check for leaks. The rubber hoses should not be
cracked or damaged, and all hose clips and connections should be tightened
properly.
Check the batteries’ charge condition using a hydrometer. At an ambient
temperature of approx. +25°C the battery electrolyte density should be 1.28 g/cm
3
(1.24 g/cm
3
with tropical acid). Charge the batteries if the density has dropped by
0.04 g/cm
3
.
Check for wear. Belts which work in pairs should be replaced at the same time.
Undo screws (A) before tensioning the belt(s).
TAMD63: Tension belt to 60 ±3 Nm (6 ±0.3 kpm/44 ±2 ft.lb.).
TAMD71, 72: It should be possible to depress the belts 10 mm (0.4") between the
pulleys.
Get someone to help you connect the stop solenoid by turning the key switch to
the “S” position. Check at the same time that the stop position indicator pushes up
the rubber seal on the top of the stop solenoid.
Clean the batteries’ terminal posts and cable clips, lubricate them with Vaseline
and tighten them. Also check that all other connections are properly tightened
and have good contact. If necessary, spray these connections with a moisture-
repellent spray.
