I had a few minutes and went looking for the parts on the forum. Here's what I found:
For the Manual Mainsail Furler:
Bearings: Source , Motion Industries - Tapered bearing item # 32009xm-90kmi , Bore 45mm, OD. 75mm, Width 20mm , Manufacturer Timken
Ball Bearing , item # 9105k Bore 25mm, OD. 47mm, Width 12mm Manufacturer Fafnir
Oil Seals : Source , Metric Seals Inc. 45mmX60mmX7mm 25mmX33mm X6mm
You will need one each of bearings and seals
If you find the seals and bearings for the motorized gearbox you might post them.
