Don't fool around, get a pump from Dave Kostansek in Ohio. With out the correct tools you are asking for trouble. 440-293-4079 before 8 pm Ohio time.

The Hudson waterpump shaft and double bearing assembly is a standard item used in many different automotive and non-automotive waterpump applications over the years, is available from most bearing stores and is not expensive. From memory its a 5/8" shaft x 30mm or 32mm OD bearing, the shaft will be over long and each end will need to be trimmed.

For the seal use a 5/8" pool pump seal and some ingenuity and you will have it done.

As to getting the wire clip out, it either is rusted in, the usual penetrating oils etc will help there, or the bearing has moved slightly in its housing and is pressing hard on the clip, gently tapping the shaft back and forth will fix that.

While still living, Bernie Siegfried was known to provide hands on technical seminars. For those who had the opportunity to participate in those events, you will remember, Bernie carried around a water pump, fuel pump and carburetor to show those who were willing to listen and participate how to rebuild each of these items. I remember vividly my first opportunity to disassemble a Hudson Stepdown water pump was after Bernie had rebuilt and the very same pump. His admonition was the simplicity of the accessory pieces Hudson assembled to support their motors made them ideal candidates for a mechanically inclined owner ‘s overhaul. I know from this experience, that the real finesse in pump overhaul was assuring the packing or seal was properly installed. Access to a press or possibly a wide mouth vise is the major tool required. Good Luck ... with the bearing and seal advise given... coupled with the manual you should be able to over haul your pump.

For water pump parts try these guys.
