It isn't the individual parts that cause this problem, it is the interaction of those parts. Lubrication points; Use VJ lube in the pedal end cup Use VJ lube around the guide bushing area on the pedal rod Use VJ lube at the top of the pedal rod nut. WELL lube the pitman with teflon spay. (NO grease or VJ here) If the pitman buckskin on top of the lever is indented replace it with new buckskin and cover the whole bottom of the skin with glue. If the buckskin under the damper tray is indented do the same. Check if there is a coil spring on the tray. It is better to remove this spring than the lever spring. Either could be too strong and will have to be cut, with bolt cutters, to weaken. If all this is taken care of and it is still stiff then the pitman is binding in the hole. There are two fixes for this jproblem. 1. Replace the hole lining with new cloth. 2. Remove the felt and drill a 5/8" hole 3/8" deep in the lever and the tray and glue a 5/8" punching at each end of a 3/8" dowel of a length to connect to tray to the lever. If it is done carefully you will not need to increase the diameter of the pitman hole unless the new jpitman rubs on the sides of the hole. Number 1 keeps things as they came out of the factory and number 2 changes things to the new factory arrangement. #2 has the merit of being frictionless permenently. Newton nhunt@jagat.com
