Quoted from terryb:It's not an insignificant project, but I always remove the two gearboxes, clean out all of the old grease and apply Super Lube Grease (won't attract dirt or gum up over time). 15 year-old grease is probably the main reason that gearboxes fail.
Thanks. The Super Lube is on order....
