mizzen furler failure
What would be the preventive maintenance procedure for this gearbox?
From what I understood of this chain:
1) remove the black ring
2) unscrew the outer casing of the horizontal shaft from the vertical gearbox
3) remove the horizontal shaft from the outer casing by pulling forward
4) clean both , removing surface rust and polish
5) lubricate and reinstall
Is it that simple if it is functioning normally?
