Greasing water pump

[TMarsh]

I have been working on a 30 coupe for several years, finally finished it and it is just what I wanted. Kewanne green and elk point. My question is, I have a leakless water pump, I am sure of, but I am not sure about greasing it. It was purchased from Snyders , I think, but I know it was a reputable vendor. The pump has modern zerk fittings and looks greaseable. I know you do not want to put to much grease in, but I need some advice about lubing. I also have a new radiator and do not want to stop it up. When I pull out the fittings there is grease on them.

For me, once the pump is assembled I never add grease to the rear bearing. I do grease the fan bearing at least 1 x per season.

A proper waterpump grease is one with a low enough melt point that it won't clog the tubes. The rear bushing will need grease now and then. The front bearing may or may not be a sealed bearing. Sealed ones can get by for a number of years without service. The old roller type will need service now and then.

I have an old grease cup on my rear bearing that I pack with K-Y jelly, I'll give it a 1/2 turn every now and then, the front bearing I grease as normal.

The original type of water pump grease fitting works much the same way. Fill the cap with your favorite flavor water pump grease and screw the cap back on. The grease is pushed thru the fitting into the water pump. The small amount of grease pushed in prevents you from over lubing the rear bushing.

Yours obviously is more convenient as you don't have to fill the cap each time
