Hello Dana 67. Thank you very much for the lead in order to find the information on the 65 Valiant Convertible motor/hydraulic pump assembly. There is a video on YouTube, as you directed, for the repair of a 1963 Falcon Convertible Hydraulic Pump (identical to the 65 Valiant). The guy does a great job by tearing down the entire reservoir, the pump mechanism, and the motor. In this video, it shows where all of the seals are (replace all), and where those steel ball bearings go (they fell out when I disassembled ). The two larger ball bearings go in the hydraulic pump itself and they act as check valves. The third, and smaller ball bearing rides in a cupped depression on the end of the 12V DC electric motor shaft. This small ball bearing is a devil to get to stay in place during reassembly, so I put just a dab of grease in that cup which holds that third ball bearing securely in place during assembly. Everyhing is now in the correct place. This motor is thermally protected by a set of points that, I assume, break open when the motor overheats. I sanded these points, slightly, to insure good contact as they were quite corroded after sitting for 20 years. Thank you, once again for where to find the information. Indeed, the falcon, mustang, valiant, and I would assume all of the early a body are the same motor/hydraulic pump assembly. I appreciate your help on this. Old Dart 66.
