Inspection and repair on LOHMANN+STOLTERFOHT GAA560WN 1500W gearbox

Conclusion of the overhaul from this gearbox are that the bearings were on his running hours, minor corrosion and little spots on the gears from running hours. The spots and marks that you see on the gears are from still standing, because of the vibration from the ship comes in the still standing gears on each other.

probably would input shaft bearings not make his running hours, that is because of the wrong storage of the spiroflex elements, with a wrong storage the Spiroflex isn’t balanced any more so you get vibration on your coupling, shaft and bearings.

Recommendations
For the right storage of the spiroflex elements, GBS recommends to hor
