I bought and installed a new style water pump on my 1930 Model A. It has a grease fitting on the housing by the fan. It has a strange looking knurled, brass turned " thing" at the other end of the housing. It came with zero instructions. Do i ned to grease that pump and what is the thing at the other end some kind of grease fitting?
Thanks!
 
Sounds like a normal pump to me. Check to see if it's a zerk fitting at the front, or the original style. The fitting in the rear is the original style, just unscrew the brass cap and you'll see the fitting. You can get an adapter for your modern grease gun, or use the original grease gun that came with your tool kit.
 
James Rupert made a greaseless and leakless waterpump that would last a decade. Too bad he retired!!!!

All 4 of my Model As have a water pump like those, only I made them years ago.
To the OP, the fitting you describe at the back is a screw on cover that exposes a grease nipple that you can use an appropriate grease gun on BUT ONLY A LITTLE GREASE. When I assemble a water pump, I fill the passages to the rear bearing with the grease gun but only use the cap from then on. I put a little grease in the cap and screw it on. That forces a small amount of grease through to the bearing. I use water pump grease for that (which is not a grease at all - it is a wax that melts when the motor is warm and won't clog up the system.)

Thank you Synchro, I have been trying to tell members of our club to do it that way for a long time and now you have confirmed it for me.

Synchro, I got the leakless from Snyders. I have yet to put it on as I wanted nothing to happen before the Old Car Festival this year. do I need to do anything fancy to get the new aluminum 2-blade fan on the shaft and what about greasing that pump.

Can you grease that pump from Snyders? I think those you cannot.
 
Ill check the rear brass cover. There is a grease fitting in the front of the pump that I read was just a phantom fitting to make it appear that the pump was original. The new pump has been on the car since the beginning of the year.
A strange thing happened today. I want for a short cruise in the Model A, just a couple of miles. Just before I got home the A overheated. Steam was coming out from the hood and spewing antifreeze all over. I opened the hood and all the antifreeze seemed to be coming from the water pump and then, of course, the fan was blowing antifreeze all over.
Time to investigste!

Don't trust what you've read, unless you've verified your pump bearings. Most pumps require grease in this location, even the "leakless" pumps. The sealed bearings require machining on the housing to fit the sealed bearings, and very few do this today, if anyone.

The roller bearings were never a failure point, only the rear bushing with the old lead seal. They would leak. The leakless pumps usually have o ring seals and a modern seal on the shaft to make it leakless.

The front very likely requires greasing. The rear bushing probably only requires a half pump or squirt of grease at the same time.
 
I did some investigating and found that that rear brass thing is just a cover for an old style grease fitting, as is the front grease fitting. I removed them both, replaced them with modern Zerk fittings and pumped a little grease in both.
As far as the overheating, I refilled the radiator, started it up and let it run for a few minutes. it started leaking profusely from the lower drivers side water pump stud and nut.
Im hoping its just the gasket but I'll know more when i pull off the pump.
Thanks for all your help. At least the grease fitting problem has been addressed!
These cars are easy to work on, but that's good because you're always doing something to them. Always something breaking!
Thanks again!

I find this interesting,I made my last water pump out of parts removed to make a leakless pump, so far it has lasted 40 years and the guy with the leakless pump is on his third replacement leakless pump.
Is it really an upgrade over the stock pump?
 
It seems that no one has mentioned that special grease should be used, at least on the rear fitting. Original pumps had a small cover on the rear fitting to keep the dirt out, the large brass nut was adjustable to keep the packing snug on the shaft, to prevent leaks. Water pump grease is still available at most auto parts stores. A special wrench was used on the big brass nut, most guys used a tool called a screw driver.

I am using the A-8502 water pump from Snyders. It is a Leakless pump that requires some grease. The front grease fitting on this pump is for appearance only. It does not require grease. There is a packing nut on my pump on the rear and it comes loose from Snyder’s and the packing nut is left loose on these pumps on purpose. Do not tighten this pack nut, it is for emergency use only. in the event that the seals in the rear of the bushing would happen to fail, you can tighten up the packing nut and be on your way without being stranded somewhere. If you tighten the pack nut up, it will seal the grease grooves in the rear bushing and will prevent grease from lubricating the rear bushing. Lack of grease will cause the shaft to seize in the bushing. The rear grease fitting should be lubricated every 500 hundred miles. Because the rear bushing of this pump is sealed, it is necessary to back off the pack nut when greasing. This will allow the air to escape and avoid damaging the seals. Pump grease into the rear fitting until you see it coming out between the shaft and the bushing.
I like the “belt and suspenders” approach with this pump and I have about 800 miles on it so far and it is working great.
 
If it is the"greaseless water pump" from Snyders it is completely "greaseless". Both of the two fittings (look-alike front grease nipple, and the brass colored screw cap) are only ornamental. They are both blind. I have found it to be louder than the old fashioned grease requiring pumps...but it eliminates the grease spattering all over the inside of the hood. A mixed blessing.

Snyder's sells a water pump cover. https://www.snydersantiqueauto.com/product.htm?pid=979236&cat=0 Works great containing water/grease splatter.
