Rolland; My 62 300 convert - setting for some 25+ years- the pump and motor were full of dried up break fluid. The lift cylinders were frozen - could not get them to move when I had them out and clamped in a large vise. I ended up adapting my 5 ton porta power hose end with fittings that I could tread into the cylinder ends where the hoses connect. Pumping the porta power broke the pistons free. I then alternately filled the cylinders inlet and outlet with alcohol and worked the pistons in and out many times - thus flushing out the old dried up crud. I had purchased new hoses and got a pump out of a wrecked 89 Chrysler K car convert. The pump's rubber foot print perfectly matched the original mounting holes and hoses connected. My top works up/down beautiful, fast and is immediately responsive. I had the cylinders, hoses and pump (with the filler hole up) connected and, using battery/jumper cables ran the pump fwd and reverse, adding trans fluid as I bleed the air out of the cylinders and hose. I then reinstalled the the whole works (still hooked together) into the 62.
