Moin, has anyone found the ultimate solution against the eternally leaky main shaft on the old 4-speed gearbox? Flow grease does not come in, so I killed the main shaft 4 years ago. Mine is an 81er dome gearbox with 1 1/2″ belt and primary sheet metal. A support for the main shaft has always been there. Because of the replica gearbox: A buddy bought a new Rev-Tech last year, what should I say, it’s pissing again. mfg Miller
