Still working through a number of little problems necessary to get my '50 F-3 running (at least enough to get it in and out of the shop).

Next up: leaky water pump. Water leaks out of the fitting or plug on the front of the motor directly below the water pump pulley on driver's side. Doesn't appear to be leaking from the pulley bushings, just a steady stream out of what looks like a plug below the pulley. Looking at the exploded diagrams of the water pump - it looks like leaks is coming from a bolt head (part 20514-S).

I've searched the forums, but can't find much on replacing/rebuilding these pumps and I'm kind of perplexed by how the pump looks to be part of the motor mount. What's involved with removing the water pump and can it be rebuilt, or are there obvious parts to replace or does the whole pump have to go? Also, do you have to lift the motor up to get the pump out? I swear I'm going to buy a shop manual soon...

I appreciate any input you folks can offer.
