  • Frustrating Water Pump Rebuild

    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.

    The new bushing with the better seal is shorter than the leakless bushing. The leakless pack nut bottoms out. Now I am wondering what I need to purchase without buying a whole new leakless kit. Any advice. This really should have been pretty simple, but I sure have made it complicated.

    I'll see if I can find my picture, but I'm sure mine was the same length as the original bushing. Found the picture, but unfortunately I had the bushing standing on end.

        Give Steve at Bert's a call.

          Finally figured out the issue on the water pump. I went to Mike's AFordable on Saturday (they had their grandfathers day car show so it was a worthwhile trip). With Mike and one of his employees, we found that the leakless pack nut that they sold would not fit with the new leakless bushings they sold. The pack nut was too long and would bottom out on the casting before the leakless packing would contact the bushing and seal. Turns out there was a slight relief line on the outside barrel of the pack nut where the nut must be cut back to in order to use with the new bushing. (There new leakless bushing is the same length as the one I got from Bert's) They were very good and took two parts out to the shop and machined back to that line and it works fine. Finally got the new Snyder head on and just a few more little tasks as time to fire it up for the first time in over 30 years!

            Leakless Water Pump
            by Roadster Rich
            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...

            Leakless Pump Follow Up

            I am so sick and tired of water pumps that leak! Just about to fire up an engine that I rebuilt myself (just rings, lap in valves adjust all clearances, rebuilt dizzy, carb and water pump). I filled with 50/50 yesterday morning and saw a very slow drip at the pump. But from every thing I can tell it seems to be coming from the pressed in bushing and the pump body. The drip only was about 1/3 cup...

            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....

            A couple water pump questions
            by rheacox
            Before heading up to the New England meet the rear bushing on the water pump started screaming at me... strange since I rebuilt the pump about 1000 miles ago. More grease helped but didn't eliminate it entirely. It makes about 3/4 of a rotation and hits a tight spot. I did reuse the old bushing (it was a leakless one) and just replaced the old seals. I'm back looking at parts and see Snyders sells...

            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?

            Original and leakless water pump info
            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...

            Water Pump Opinions Needed
            by Antique_Iron
            Still a newbie here- 28 Tudor unrestored original driver (not a show car or fine point): the water pump leaks pretty good and there is plenty of end play going on. I'm capable of rebuilding the pump but I am interested in everyone's opinion on what new pump to purchase. To me it looks like the units with the modern bearing and seal is the way to go.

            New water pump packing
            by Dennis
            I was a little excited when I got my new water pump today. I decided beings I’m pressed for time and I don’t have parts to rebuild an old one I’d just get a new leakless from Bratton’s. So I took it out of the bag and looked at the the top near the packing nut and saw a hole above it in the housing. So I thought oh a weep hole. Looked down between the impellor and housing and saw the seal...
