Another pair of guys go around with some sort of air driven contraption that makes lots of noise. What are they doing with it?
They are shooting a stick grease into the bearings on the drive rods. Because of the forces exerted on these bearings, regular greases would not provide adequate lubrication. A stick grease is used instead. It comes in a large block and we use a press to extrude this grease into a hot dog shaped stick which is then rolled in graphite. Because of its consistency, an air driven gun must be used to shoot the grease into the bearings. The crewmen connect the gun to the 1522’s air reservoir and use this pressure to shoot the grease.
