The problem was the water powered lower swing arm bearing (bushing) had worn out (had rubbed away part of it's flat surface). First I removed the large screw with the big flat finger grip flanges on the top side of the lower swing arm assembly. this assemble looks like a big hub cap. Lift the assemble up and off the attachment stem. The bearing goes on top and the seal on the bottom. Both just push in place with your fingers. Reinstall the assemble on the attaching pivot point that it was removed from and secure with the large thumb screw first removed. Spin the assembley to check for any binding. Do not over tighten the thumb screw. Water pressure is all that drives this assembly and it should always turn with no obstructions.
