Considering sending out an original 1969 383 mopar water pump for rebuild.
I'm aware an over the counter is probably cheaper.

I see that RockAuto offers this service. Has anyone used them for this service? Would like to hear any other suggestions for rebuild service used by members.

Thanks

If you are looking to keep your original pump Make sure they are returning your pump and not doing an exchange


In theory, there is no difference between theory and practice. In practice, there is.

You can do it yourself if you have a press. The bearings and mechanical seal are available along with a new impeller. I have rebuilt about 4. Company in CA sells the parts at wholesale prices to public. Older service manuals have the procedure.

ASE in Los Angles CA. Google will find it, but there are other ASEs so add Water pump or city to locate it. They have a website.

Flat rate for a WP rebuild was .2 hours, 12 minutes.

I would not trust RockAuto to rebuild anything on one of my cars. They are a low price warehouse sales organization, not a parts rebuilder. If they are offering the service, they are surely sending to a third party or just doing an exchange.

Yep, as I suggested earlier I am about 99% sure that theirs is an exchange through a third party rebuilder. That rebuilder is probably paying an illegal less than minimum wage to do the "rebuild" in less than flatrate time. Not what you are looking for.

You don't even need a press. A table top vice is more than adequate. Don't pay someone to do this, if you can change out a spark plug, you can rebuild a big block mopar water pump.

Maybe an aluminum housing, but you are not going to do this with a 50yo cast pump and a vice. Trust me. I have separate many more then I have rebuilt. The casting can break if not properly supported. While it is easy to pull the hub off, your not going to save the stamped impeller unless you support it correctly and press the bearing out through the front. That requires a long, and properly sized fitting to sit the snout of the pump on. Pushing out the through the rear requires proper support of the casting as close to the impeller as possible to avoid stress on the casting.

I am no machinist, but I did have access to a press and the various fittings and plates to do this right.

Kellogg Automotive is another site with documents on the installation procedure, and the shaft seal info and set height. You need to do some homework first, but it isn't hard if you have access to the press and some basic material to work with.

The bearing will have stamped part number, the key is if it is already over sized OS. Many are. You want an oversized bearing shaft to ensure good grip on your hub and impeller. Or go with new. The hub is something that may not be seen once pulley is on, but an original is an original, and the aftermarket stuff is not. So if your going for total OEM look you have to save the hub.

I find it hard to believe that a dealership mechanic could do this in 12 minutes. A rebuilder siting at a bench doing this all day maybe. Hard to believe you could make a living doing this in the 60s.

I have, and i will, which is why I posted. If the pressure of a rig you made in a vice doesn't cut it, heat and a candle will make it cooperate.

Map gas from wal mart is what, 16$ a container? A press is the proper way, but some folks will never outgrow their roots and do the cheapest way possible.

That is the place. New website. The impeller was the 3.5" 2-53. If you search they list it. I would call. They were very helpful. From my notes was back in Dec17 I ordered my parts and did this on several pumps.
