Major overhaul at time of drydocking vessel
• Thoroughly flush the machine prior to disassembly necessary parts and
assure that no hazardous material remains in the machine. Be observant for
leakage and remember to fill in the service card.
• Check all seals, bearings, gears and ball bearings for wear, if necessary
replace.
• Change all grease in the gearbox by dismantling the unit, removing all
old lubrication and adding new grease. See previous pages for grease
recommendations.
• Order the service kit “KIT 40RT ODU” for the drive unit and change all parts
included in the kit.
• Order the service kit “KIT 40RT OGU-2” for the gun unit and change all parts
included in the kit.
• Order the service kit “KIT 40RT WGU” for a complete wear kit, both for drive
and gun unit, and change all parts in the kit.
• Make a complete survey of the gun unit installed below deck. Check that the
nozzle has a free flow and is properly attached.
• Inspect main pipe (pos. 126), top shaft (pos. 171), turning shaft (pos. 175)
and lower housing (pos. 179) both for wear and the welds for damages. If
needed, replace or send to workshop for refurbishment.
