I have a leaking '37 120 water pump. The bushings seem to be OK, and tightening the packing helped for a few hundred miles, but the packing nut is now bottomed and the leak is back. The fan seems to be very straight and balanced. Fan belt is good and not too tight.

Does anyone make a 120 water pump with "modern style" seals and bearings?

I have some (old) new packing, but I don't know what it's for. It appears to match the Packard shaft size. I don't know if it's a full set. I've got four split rings that look like little donuts.

It looks like I can take the pump and fan assembly off the car to work on it (or replace it) more easily than trying to pull the fan and pulley with the pump in the car.

Terrell Machine in TX rebuilds them. Not aware of any modern seal replacement/rebuilds.

The “modern” style pumps “exist”. IF you can find one. They are fairly rare, but they do pop up from time to time. I have one on my 37… had it recently rebuilt by the Dutchman…

But no… nobody is making a modern style actively….

Thanks for the information. That's bad news about the modern type non-availabliity, but good news about Terrel Machine. I'm about 80 miles from Terrel Machine, and will contact about getting a couple of sets of packing for my pump. The bushings are tight in mine and the shaft looks very good.

I'd much rather have a mechanical seal/ball bearing pump on the Packard. The old style pumps are prone to leak coolant out and air in, and they can also allow oil or grease to get into the cooling system.

Here's a "modern" style pump that I was lucky enough to find. Kept in having issues with the original myself.
