Water pump trouble

[Joe Flanagan]

Today I stripped out two of the threaded holes on the hub of my water pump. I was attaching the fan when it happened. The hub was sketchy to begin with and I hesitated to use it but I chose to in the end. The four holes in the hub are close to the edge and there is a piece of the hub missing at the edge of one hole and a section ready to come out around another. These are the two holes that stripped. I had a surplus pump on hand and I figured I'd remove the hub off of it and switch it with the bad one. I drilled out the little pin that goes through the hub shaft and then tried to remove the hub with a puller. I actually snapped the hub--broke a big piece right off it. According to the exploded diagram in the manual it looks like the hub should come right off the shaft. I guess this particular hub was really frozen on there. So I'm on the hunt for a pump I can cannibalize. My pump is completely rebuilt. It's just got these two stripped holes now. Hopefully I can find a replacement hub.

That's the fear of working on these cars. I'm always fearing I'm gonna break something 'cause it's so old. Good luck with the pump.

Spend sixty bucks and buy a new water pump.

Joe I've got a few laying around since I follow Don Cs method. I'll look tomorrow

[Rodney Bullock]

Hey Joe, I was thinking of you today. I was taking the fuel pump off the 41 Stude and I thought about cracking it open and trying to repair the diaphram. I looked inside and there was a 1 inch tear in the rubber. I though the thing in a box and monday I will be sending it to antique cellar. They have a rubber diaphram that is resistant to todays fuel. I know Joe would have fixed it but I am not as skilled as he is:rolleyes: I bet by tomorrow Joe will have invented a water pump that works with out that stupid fan;) I gotta take the wife to the market however after I finish I will check on you(If it don't rain)

[Joe Flanagan]

Rodney, I think I have a couple of spare diaphragms in my garage. I took them out of my fuel pump and I was surprised that they looked practically new. Mine is the dual action pump, though, and I think yours might be different but you can check it out.

[Jim Yergin]

Dang it Joe, if we had known you were going to do that you could have taken one of my extra old water pumps when you were out here yesterday. You are welcome to it whenever you want it.

Jim Yergin

[Joe Flanagan]

Jim, I feel bad about taking all your stuff but if you want to part with a water pump, I will be glad to oblige you. All I need is the hub. Also, do you want the generator back after I yank the pulley off it? I could put the narrow pulley on it and at least you'd have a whole generator. I forgot to give you back your hydraulic jack oil, by the way.

[Jim Yergin]

Joe,

If you don't need it, you can return the generator without the pulley.

[Don Coatney]

Joe;

When I get home next week I will see if I can remove a water pump pulley hub from one of my spares and send it to you if you need it.

[Joe Flanagan]

Thanks, Don. I'm going to see if I can remove the hub from Jim's. I'll let you know how it goes.

[Joe Flanagan]

Today I took a trip out to Jim's and got one of his spare water pumps. I removed the hub with little trouble and switched it with mine. Problem fixed. I liked the looks of the impeller and shaft on Jim's pump, so I switched those with mine, too. The shaft on mine was badly scored, which I don't recall when I rebuilt the thing. My impeller had a chunk missing out of it, too. Now I just have to replace the gaskets that go between the pump and the block and the pump body and the back cover of the pump. Has anyone ever just used straight permatex for this?

[Plymouthy Adams]

this gasket I think is available at Advance Auto..plus it could be so easy to cut one from gasket stock and install..keep the goop and gunk out of your engine and from taking away the appearance of a refreshed engine..

[Joe Flanagan]

I've got gasket stock. I've just never been very good at cutting the curves. I'm surprised Advance Auto would have it. There's one not far from me.

[Young Ed]

Ask Rawge you need the wifes good scissors.

[Joe Flanagan]

Thanks for the idea, Ed. I'll just blame it on you when she finds out.

Just grease the gaskets. No need for permatex. This is a low pressure area of your engine. Grease will soak into the gaskets and expand them along with the engine coolant. No leaks, easy removal and replacement without gasket relacement.

Don, does grease work OK with the valve cover gaskets. I am going to take a look inside to check for sludge as my manifold will soon be off. I know you recommend it on pan gaskets. Grease both sides or just the one?

[Joe Flanagan]

Thanks for the tip, Don. I followed your advice on the oil pan. What I like most about it is you don't destroy the gasket if you have to take things apart.

I have seen two types of valve cover gaskets. Cork and rubber. Grease the cork gaskets on both sides, the rubber gaskets should work dry as is with no sealent required. My personal preference is the cork gaskets.
