1934 Auburn 8 Cyl.

I seem to have to give the water pump a shot of oil more frequently than I would think necessary-- about every 100 miles. If I don't, I get a bit of bearing noise. If I put too much in, it leaks out the shaft and the fan blows it all over the engine and firewall. No water leakage and it sounds smooth when oiled.

It doesn't seem that there is any felt under the plug in the oiler... should there be?

Your water pump seals are probably failing as water is washing the lubricant away. The pump should have a grease cup with a check ball and be filled with waterproof grease.

Hmmm. What I have is a 1/4" pipe thread plug on top of the pump assembly. If there is a check valve inside, I can't see it and there certainly isn't a grease cup.

My Auburn owner's manual says to lube the water pump with "medium heavy engine oil" so that's what I have been doing, but I now that you mentioned a grease cup I find that 1934 Auburn Service Bulletin #64 says that's what I should have as well.

So apparently, I need to obtain a proper grease fitting before I burn out the bearings. Do you have one?

Auburn/Cord Parts replied the topic: Grease Cups
We have grease cups but none with check valves. With waterproof grease they should work OK. The cavity for the shaft and bearings in your water pump holds quite a bit of grease.

Price: $7.50 each Part #812B

Hi Richard :
It sounds like you need to rebuild the waterpump. I would suggest MODERN sealed bearings (there are two of them) and a new John Crane neoprene / ceramic seal.

I appreciate all of the information here. It isn't enough sometimes to just read the manual.

Curt,

As usual, your advice to rebuild the pump seems sound. I have temporarily put in a zirc fitting and filled the pump with waterproof grease. It's quiet and doen't leak, but I now have doubts about the thing.

I assume that there is going to be a bit of machining to change the pump to modern bearings and a seal. I'll be looking for a shop that can do the work in my area.

By the way, I looked all over the tub wall behind the rear seat for holes that are for mounting the footman loops for the top. There aren't any, so I assume that is the way that it came from the factory. Some one said earlier taht a number of cars were not fitted with the hardware for the top. I'll be contacting you about the footman loops and will get around to drilling holes for them one of these days. Are they supposed to be mounted with machine screws or through-bolted?
