Thanks Guy for your advice
After 4 hours of driving a steel
wedge all the way around the top of the gearbox and the bottom of the hardwood packing washers under the deck
, the winch finally dropped 1mm. A bit more wedging, and it dropped a bit more. A few judicious hits with a steel
drift on the top of the shaft, and it finally came free. One of the hardest jobs I've ever done on the boat
, and in a very confined space. The studs were seized onto the allow gearbox casing - obviously Duralac wasn't used in the first place.
The winch works perfectly after a very good cleanout - especially the debris around the brushes
. Very relieved!!
By the way, there were no oval slots in the top of the gearbox, so I guess it must be a slightly earlier model. I can't find any Serial
No. on it. The gearbox sight-glass shows it is half full of oil
Once I find out how to reduce the file-size on the photos I've taken, I'll post them on the Forum for the benefit of others.
