I'm a cheapskate and can't recall ever attempting such a thing. If you do get it apart, I would wonder where you would obtain the bearings-seals etc.

4 bolts to take out/put new one in.

Are you doing a concours restoration?

Never have so I'm just thinking out loud. I think pressing the shaft out would be the easy part & more difficult would be finding/adapting a puller to pull the vanes off of the shaft (which you'd want to do first) without damaging the vanes

You have to be both a cheapskate AND a glutton for punishment to try this one - particularly since the net savings would be about $5 by the time you were done !!

Thank you all for your input. Sounds like a no go. Can anyone recommend a shop that will rebuild my pump?

I don't think a water pump can be rebuilt. I tried it once and didn't have any success. The shaft busted the housing when I tried to press it out.

Contact your local auto parts store, NAPA would be your best bet probally, and ask them if they can have yours rebuilt instead of just exchanging it

I know there are, at least there use to be, commercial large volume rebuilders that would do that for a few dollars more than the standard over the counter rebuilt pumps, they where charging the extra for tracking that core internally and returning it back to that dealer

I know of a guy that comes out to Spring Fling and has original core rebuilt through a local auto parts store. I think he sells on Ebay too.

If you find a place that will rebuild your core, engrave your name or something on it and show the person receiving the part.

If you read the whole ebay listing, he indicated that his rebuilder will install the pump kit.

Sometimes one really has to wonder about folks. Never have I heard of such a "backasswards" way of doing something. Why the cost alone one could get at least 3 impellers for the price of the re-build. Just don't get it? Then again maybe I'm not supposed to...

Re: BIG block water pump disassembly? - 12/29/12 07:14 PM

Actually never rebuilt one for a BB mopar but I did have to rebuild one for a Turbo charged Perkins Diesel engine. Kit was very expensive but I put it back in and logged 2200hrs more with no problems. I am sure it could be done but not cost effective. I had to do mine cause the replacement was in Germany and was a couple hundred dollars plus shipping and it broke on a friday. It was on a Grape harvestor and I needed to finish harvesting before a hurricane and luckily found the kit about 50 miles away at a parts depot....

Re: BIG block water pump disassembly? - 12/29/12 07:25 PM

I am aware I can go down to my local auto parts store and buy a rebuilt water pump for $45.00. However my cars ( which I am the original owner for 40 plus years) still have their original water pumps. I am trying to keep the cars all original and the rebuilt pumps are not the same shape nor do they have the Chrysler casting number in them. I can have my alternator, power steering pump etc. rebuilt, why not the water pump. I just need to find someone who rebuilds water pumps preferably located in southern california. Thank you for any help.

sbcjd you certainly ain't getting much love on this request. I'm on your side & (some) people here do tend to get a bit owly especially on the weekends. Yeah if you can locate the seal assy I think you'd be well on your way or as said mark it on the inside where it dont show & find a rebuilder.

Re: BIG block water pump disassembly? - 12/29/12 07:49 PM

The rebuilt parts store water pumps do not look at all like the original cast iron water pumps and do not have the same casting and date marks.

This is really a resto topic.

I'm sorry that people are too ignorant to understand someone else's perspective or opinions that do not match thier own.

I don't think the car was mentioned and I'm not going back through all the posts to make sure BUT unless this is one of the rarest Mopars ever made, keeping that original pump is just a load of BS !! Are the tires original? Hoses? Belts? Air filter?

Thank you for your reply. I will try this question on the restoration forum.

Buddy, I don't want to sound rude, but the deal here is simply. Althought lot of ppl has been told it doesn't worth and is better and easier simply replace it, he still ( for WHATEVER REASON ) wants to restore his existant pump.

if cheaper or expensive, harder or easier, faster or slower, IF ITS POSIBLE, like it is really, then why not?

If in fact I'm able to do it overseas on local shops, why not up there where you have all the parts in stock easier ?

I didn't rebuilt mine last time ( like I did before ) because all the local shops only had the 8 blades impellers and I wanted to use the 6 blades impeller this time. Found on ebay a original Mopar piece rebuilt, not correct year and cast though, but at least pentastar casted.

There is also a guy in Phoenix AZ that does it. He is not cheap, $150.00 for a pontiac water pump. IF you want his contact info just PM me.

Rebuit the one in my welding machine last year, tractor year before. Bearings can usually be found at a bearing supply. I use to get rebuild kits at napa, but that was a long,. long time ago. I think mopar parts are high until I buy perkins, duecth, etc. Heat & cold are your friend when disasembly/assembly. We have became parts changers, myself included, due to time, cost, don't want to. It's easier to go the parts house, pick up an overseas rebuilt part & install. Wait we hate overseas junk, never mind!

Yes, you can rebuild the pump yourself, or send it out to have it done. I own a couple of NAPA parts stores and we rebuild pumps in our shop based on $$ and availability. The common pumps you can buy cheaper as a factory rebuilt unit. We started doing them our self for the farm, and industrial pumps because of how $$ they are getting.

You can have your pump rebuilt by A-1 Cardone in Philadelphia pa. They probably do about 90% of the rebuilt water pumps for the automotive and light truck market regardless of who is selling it or what it say's on the box. If you don't mind spending around $100-$125 to have yours done, send it to A-1. If you have a press and some patients, you can buy the parts for around $30-$40. You just need to know where to look for the parts.

Sometimes we do stuff just because...I don't see the downside at least trying to rebuild your original. Worst case is you can't and end up replacing it anyway. I applaud you for trying. I also see another possibility with this. In some of the posts about cooling it's been suggested that distance from vanes to inside of housing effects cooling. Looking at a pump I have here it looks like that distance could be tweaked a bit depending on how far you pressed the vanes back on the shaft. It's a little outside the box but why not?

WOAH!!!! we get shops making that job cheaper down here than the price of the new pump!!! or if not cheaper, more less the same price.

That Pontiac pump must be something special!

I don't think a Mopar BB water pump rebuild service will be close to that. I paid around $30 for the rebuilt water pump I got on ebay.

So typical here when ever anything is out of the ordinary. The "Au-contraires" always get the pats on the back for their odd questions and the realistic ones get the....

or why be so hard on the guy. Oh well...To each their own I guess. Me I like the KISS principle....

Well to be fair, the OP never said that he wanted to keep the original casting and he didn't care how much it would cost. I think most people just assumed that the OP didn't understand that a new pump is cheaper then getting an original one rebuilt.

Rebuilding a water pump isn't an easy task for the average person. You need a press and a set of press blocks which are correctly machined for the task. I have a very nice electric press in my shop and the ability to custom machine my own press blocks and I still wouldn't bother wasting my time rebuilding a water pump. (I've tried it before and failed which is why I don't bother anymore.)

I'd have to be retired with tons of time on my hand before I'd even consider rebuilding a water pump. I'd do it for a Hemi restoration project where I was keeping all of the correct casting numbers, but probably not for anything else.

Not real special, 69 Firebird, but the pump was only made a year and a half. The aftermarket ones were coming with steel impellers, instead of cast ones, which would make the car run hot. We ended up using the original for 2 years, and ended up finding one at NAPA for around 40 bucks.
