  • Leakless water pump

    Is the rear brass bushing with the seal supposed to be lubed?
    Not sure what pump prior owner installed.It looks stock from exterior and shaft doesn't move laterally. Any way to tell without removing pump to see if it has modern components?

    Mine leakless (from A&L) has a fitting at the rear, I pulled it and there was grease there. You might do the same and see.

      When or if you do grease the rear bushing, I like to loosen the packing nut so the grease goes forward rather than pushing through the seal.

      Well, I'm not sure everyone is on the same page. The leakless kit that I used to rebuild my pump came with a single unit that was pressed into the rear of the housing with 2 seals and a roller bearing and NO packing nut to loosen. I did add a bit of my favorite grease on the roller but it didn't have a hole in the brass housing to enable you to use the rear fitting to lube the roller. I did however lube the front as it had the same style roller bearing inside the race with holes to get grease.
      You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

        Thanks for the tips. We studied the vendors today and wasn't aware there are so many "improvements" now supplied within the stock looking housing. The Rupert pump looks promising but can't seem to rebuild our own, lube or add packing if necessary with theirs. Not sure a tiny amount of water pump grease is a bad thing and some now provide double sealed roller bearings in both ends.
        Edit: 2 styles of Rupert pumps; only difference apparent is that the rear has sealed ball bearing and 5 year warranty vs. the cheaper one's conventional bearing and 3 year warranty. Is there any preference ?

          My "5-year" Rupert pump has been running now for 7 years and still going strong.

            Remember the R/S upper mounting bolt stud goes into the water jacket. (the hole is not blind) Use sealer on that particular one

            What Mitch said i run one.

          Finally figured out what we have after reviewing the Rupert cutaways: the sealed rear bearing type requiring no grease and no packing nut movement. There are no exposed threads at the bushing -to- packing nut on ours.One can't beat Rupert's warranties..

            There are SO many CONFIGURATIONS of "Leakless" pumps, it's sometimes hard to figure out which one you have. If it has BLANK fittings, it requires NO GREASE.
            I've heard GREAT things about the Rupert Pumps. He's a member of the Model A Club, in Bakersfield, Ca, 107 Miles South of me. I'm quite sure he has a website.

          I have a James Rupert Extreme Duty pump on my 1930 2 Door. A great product built by a gentleman. He does recommend using an anti corrosive with pump lube if you are using straight water. Of course antifreeze will cover all the bases. Just left the 25 below zero cold in Vermont and am settled in the Florida house. Model A resting comfortably in the heated cellar in Vermont.

            I have a "leakless" pump on my roadster that I assembled about 25 years ago. I have a pump to rebuild for my barn find town sedan. I ordered a leakless kit with the stainless shaft for the TS and had to get a new core from Berts, as the original had a bad crack. The question is whether the pressed in brass bushing at the rear of the pump is any different than an original bushing? I used...

            Trying to fix a leaking water pump and I am puzzled. I made the mistake of taking apart the current pump and then putting all the parts I have accumulated together. Wouldn't be so bad except that the newest leakless pack nut has the seal taken out of the pack nut (me bad) and now I dont know which way it goes.

            I hope I have loaded the pictures properly. I need to know which side of...

            I installed a leakless water pump from a local shop in Grand Rapids Mi. I was told to not grease front fitting. Rear needs grease he says. So, was told ...not to much grease. As I removed brass cover found brass fitting. I did not have a grease gun fitting to use on his fitting. So I removed brass fitting some anti freeze ( very little) dribled out. I check with light and there looked like some grease...

            by JtownJoe
            I've had a "leakless water pump" on my 30' Tudor for a few years and despite trying to put grease in the rear fitting during period maint. no amount of pressure will allow grease into the fitting. After removing the rear fitting for inspection, and probing around in the hole in the casting, I have come to the conclusion that the casting must not have been drilled all the way through to allow...

            by Tom Wesenberg
            When I rebuilt my water pump in the 90's I rebuilt it completely original, and it never leaked a drop in over 10 years. When I did the block and radiator flush with vinegar I had a real mess after the vinegar removed the grease from the packing rings. I then installed the new rear bushing from Snyder's with the double lip seal. The seal will help ensure the coolant and grease stay separated. I loosen...

            I am looking at replacing the water pump on my 28 Tudor.
            Ive been told that my engine is a Jan 31
            the replacements offer one for the 28-29 and one for 30-31
            Im guessing I need one for a 30-31?

            Also I have seen that Leaklessapumps make a pump with sealed bearings on either end.
            the Model A venders offer pumps with sealed bearings only on the front side....

            A while back, I noticed a growl in Evira's engine upon initial startup. I assumed that the starter rod stuck down again, and poked it with my foot. "Growl be gone", I thought, and viola, it was gone. Yesterday I needed to move her, so started her up. She always kicks off on the first rotation, and started right up, but the growl was back. This time, the growl did not stop when I kicked the...

            Frustrating Water Pump Rebuild
            by Roadster Rich
            This should be easy. I posted about two weeks ago about the bushing in the rear of the water pump. Replies were to use the dual lip seal bushing. I got info from Steve at Bert's about which bushing that was and I ordered two. I have a new shaft, impeller, front bearing race, and the cups, felts and washers for the front bearing. I also had a very good condition "leakless" pack nut....

            Water pump, original vs leakless
            by Poor Boy
            Good evening. It is still cold and miserable up here so I have been sorting, cleaning, repairing anything in sight that is A related. I am currently into a pile of water pumps. About all that I can save on most of them is the housing. Some not even that. I have several new old stock repair kits of various makes that I will be using. This gave me lots of time to think while doing mindless cleaning....
