KD14 water pump!
Ahh, yes! Hobart devised an ingenious water pump for those early machines. They had a centrigal pump attached to the bottom of the motor shaft which would pump the water out of the machine. The shaft on the pump was sort of U shaped and would engage a pin inserted thru the rotor shaft on the motor.
All the machines still had the solenoid actuated drain valve which would open to let the tank drain. They also had a water collection reservoir that had an air pressure switch attached to it for water level control in case of drain line blockage. any water that would go down the overflow would actually get pumped out to the drain since the pump ran as long as the motor was turning.The drain line from the pump had a siphon loop built into the machine made of copper and bolted to the back and then you would hook up your drain line to the outlet of this loop to your sink or drain connection.
Unfortunately, I never thought the old parts manuals would be worth anything so I tossed then years ago. But there isn't a doubt in my mind that someone here will post a breakdown of the washpump and drain pages from one of the manuals.
BTW, the weakness in the pump was the little pin that held the impeller to the drain pump shaft was not made of stainless steel and would rust out and the impeller would spin and not pump. in lieu of replacing a pump for expediency, I found that a standard paper clip fit in nicely so I would just put a pice of it in and twist it to stay in place.. a COPPER clip not a chromed one! Then I would order a pump and install it. I know it would by then, outlast the machine!
