After fighting with the pin on the grease gun, I discovered my flexible hose threaded right up so I was able to pump grease in that way and then use the grease fittings to cap everything off. I *will* be changing these to standard Zerk fittings at a later date. I used high pressure Moly grease for all the lubrication points on the lift. A single 3oz cartridge will do all the sheaves.
