65 Valiant Convertible Hydraulic Pump

[Deleted member 38666]

Would anyone have a schematic for the 1965 Plymouth Valiant Convertible Hydraulic Pump and the 12V DC motor? I took the one I have apart in order to clean it as it was sitting for over 20 years....had some sludge and dried out O-ring problems . While dismantling, 4 round steel ball bearing balls fell out, and I have no clue where they go back in the unit. If you have the schematic for the pump and DC motor, great, or if someone could direct me on where to find the information. Are the O-rings unique to the pump, or will any o-ring do? Thanks.

See if you can get the digrame of the ford mustang pump(64 and up until they went away from the fox body style umm 93 ish. those are the same pumps, externaly and might be internal.) I have an old burned out 66 convertible pump somewhere in the garage that I might be able to find and open up for you, but it'll take a couple days for me to even find it. I used a Salvage yard 90 foxbody mustang pump since it has the correct terminals on it and works well for $25.00 so I was happy.

Hello D, Thanks a bunch for the response. Yeah, it's easy to take stuff apart, but getting it back together, not so much. Actually, there are two larger ball bearing balls, and I THINK they go on that little rocker inside the actual pump, but the third, and smaller one is a big question. It would be great if you could dismantle, and maybe send a photo. Thanks, FABO, A GOOD PLACE TO BE. Old Dart 66

.. if I remember correctly that smaller one goes into a check valve somewhere,,,, now I gotta look, #$%#$%@#@.

Hey D, Not in any hurry at all. Whenever, would be great. Is there anything I can do for you? My appreciation. Thank you. Jerry

I recall seeing a video on rebuilding the pump. check Youtube or here in the how to section

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.

Really glad it worked out for you. I put my top down for the first time in over 30 years about a month ago. All I did was clean off the cylinder rods and down it went. (So Cal garaged car so that might have had something to do with it). My fluid is clear and I believe is the OE fluid from 67. (was my dads car and I don't recall him ever doing anything to the system.)

It is kind of odd that so many manufactures used the same parts for some things but it is good for us as that way there might be replacements available 50+ years later.
