Yes the Laso Pump is Brand New at $236 No core
at Parts geek

However I am leaning toward the Porsche Rebuilt Pump with plastic Impeller
right from the Porsche Dealer for $189 with 2 year Warranty

Quote from the Dealer to me to my email
Our dealership is called Sunset Porsche, 4030 sw 139th way, Beaverton, OR 97005. Factory warranty is 2 years from Porsche.
Almost all of the water pumps Porsche sells have plastic impellers. Since we are a Porsche dealership all the parts are genuine factory parts. Our dealership is called Sunset Porsche, 4030 sw 139th way, Beaverton, OR 97005. Factory warranty is 2 years from Porsche
The current part number for the reman water pump is 928-106-915-AX and we sell it for $189.89

Now Personally I find this to be the best Deal
A PORSCHE Factory Rebuilt " PORSCHE " Pump from Germany with a 2 year Warranty for only $189.89

If you were to take the time and research what you are buying instead of concentrating on the price you would see that they are selling a very old Laso pump with a metal impeller. Nobody uses a metal impeller for obvious reasons but you are now the Worlds expert on 928 WP's. What made you ask for advice in the first place because like my teenage daughters you know everything.
Nobody buys a rebuilt WP - even a Porsche rebuilt pump because all the major failures were with rebuilt pumps - Porsche NA used the same re-builder as all the failed pumps we have seen in the last few years.
Please go ahead and buy that rebuilt piece of **** pump - everyone else use common sense and buy a pump that will protect your 928. This owner is all about cheap and not the good of the 928.
Buyer beware!!!!!

BTW I would not depend on the image to mean anything, its whatever the supplier has tied to the sku.

[ROG100]

Likewise Mike but did you look at the picture? Old pump with metal impeller. And they only have one in stock.

[ROG100]

OK granted on the picture but if a deal is too good to be true it normally is. Strange nobody has bought it.
Parts Geek buy from the same wholesalers we all do and nobody is selling the Laso pump at anywhere near that price wholesale.

As for a rebuilt pump!!!!!!!!!!!!!!!!!1

[tmpusfugit]

Before I learned of Roger and started buying my parts from him I order 4 928 parts from Parts Geek. Of the 4 parts the only one I finally received, after about 10 days, was an el cheapo oil filter. All the rest was "out of stock." Makes one wonder if they have many of the parts they claim to have. Oh, and the parts I originally ordered were a water pump, the oil filter already mentioned, a pan gasket, and a starter. And then there are the 3 928 alternators I got from O'Reilly's. The first lasted less than 2 weeks, the second was maybe 2 months, and the 3rd one they gave me under warranty I gave away....buy from people who know our cars, know what constitutes a good product, and listen to them when they say "don't do that."

[Danglerb]

Many online sellers stock no or few parts. If they are located near one of the big wholesalers they get parts delivered within a couple hours for same day shipping.

I'll throw out a wild guess, no more than 25% of parts sold go to DIY, and when you get into deeper parts that number may drop to more like 10%.

The issue with rebuilt pumps is recent, the iirc USA rebuilder screwed the pooch and started using either cores that were rebuilt too many times or lower quality parts. Maybe its better now, who would like to be the test subject?

I don't know about Porsche, but Motorcraft made a huge media announcement a few years ago with comprehensive warranty terms on parts. The electronic shocks for my Lincoln have failed several times, most recently within a couple months of install when a seal failed and wrecked all the rubber parts under the car. I tried for about a month and found no way to get Motorcraft or Ford to honor the warranty.

Called them today and they had the Shipping center pull one and inspect it for me :
The Parts Geek Ad turns out to be a Old Stock ( I expect ) Pump with Metal Impeller
so worthless for my Needs .
However REBUILT : the Porsche Factory MAKE"S THIS Pump with Factory Warranty ( 2 Years ) has a Plastic Impeller however is best to request Plastic as they still have a few metal one's come through sometimes. Price $189.89 part number 928-106-915-AX ask for Sean in parts 1 888 502 5927 if interested . BTW : No Affiliate here . That's a Porsche Dealer and the Part comes right from the Porsche Factory .
Also Has the " New Porsche Pumps" Brand New $648 ( same as rebuilt as far as all the Parts inside ) However the casting of the Pump is brand New . All else is the same inside
Same bearing / Impeller / seal and such as I understand it . Now perhaps I am wrong but that's why the Numbers are here so you can ask for yourself if interested
Link to new water pump or look it up
Note the Reman units for $189.89 are not listed you must ask for them
WATER PUMP ASSY for 1986 Porsche 928|928-106-015-22
Just trying to get my Car running with good parts at a fair Price
What I don't know and would like to know is if
(1) the Factory Pumps now have the Roller Bearings or the " double ball bearings '
(2) What to heck is the " Part Number " of of the 78 to 86 Water Pump Bearing/ bearing's , If anyone knows how to find that number
Happy New Year

[ROG100]

Never EVER EVER use a rebuilt pump - even a Porsche rebuild as Porsche NA has them rebuilt by the same company that produced all the failures. Rebuilds are handled through Porsche NA in Atlanta and certainly do not come from the factory in Germany. Most parts are built by the parts suppliers as Porsche only assemble cars and do not make parts.

This warning is for other conscientious 928 owners who are interested in heeding good advice from the 928 community.

Buy a good quality NEW pump and it will probably be the last one you have to buy. At each TB change remove the WP and check it for bearing wear - if good re-install it with a new gasket.

[aluminum]

So Anybody have the Part number for a 1986 Porsche 928 Bearing for the Water Pump ?
Seems to be very hard to find this Number or Numbers of the Bearings.
This 1986 Porsche 928S has a Rebuilt Pump installed Vis the Porsche Audi Dealer in year 2000
and just failed . The Plastic Impeller made a polished spot on the block of no Consequence , Perhaps 1 Thousands of wear .
My 1980 Porsche 928 has a Rebuilt pump I Installed about 6 years ago still running just Fine .
If I bought a NEW PORSCHE 928 Water Pump as soon as I drove it its used lol
Perhaps someone could enplane what the difference is between a Rebuilt Pump and a New Pump other then " the price "
Same casting
Same Bearing ( excluding the China Crap )
Same Seal
Same Impeller
I Suppose that some hidden stress crack may not appear of the like but rarely I expect .
If I can Find one I well just change the Bearing as that's what Fails all the Time in the 928 Porsche Water Pumps I am hearing . The Bearing go's then the Pump Leaks past the seal
Naturally if the Bearing going out and brake's the Casting you need another .
Now I know of a lot of Purists who would have nothing but the Very Best . And a Lot of salesmen who recommend this and that
Heck if your really Rich and and want the best then by all means get the best . A 14 K Gold Steering wheel Might be considered also
UPDATE : Have Ordered the Part right from the Dealer Here in Las Vegas 928 106 915 AX Evan Less Money $188.32 + Tax Total Cost
No Core Charge with this dealer , Just bring in a Non cracked Core
Does come from Germany and takes 3 weeks so well have time to fix other stuff wrong with the car . So Porsche Factory Pump Composite Impeller with all factory Parts and Warranty .
Called Atlanta Porsche N.A and they do not sell or supply Parts.
They just direct you to a dealer . All Parts come from Germany.
Was hoping they Had the Part in stock But No .

How can you check the WP and be confident that it is in good shape?

[ROG100]

Providing you know the originality of the pump - new pump with plastic impeller - remove the pump - spin the pulley and impeller and look/feel for bearing wear. Bearing will not feel smooth if it is going bad. Move the pulley and impeller to feel for any "play".
If all feels good and there is no sign of water coming from the weep hole add a new gasket and bolt her up again.

As you seem very incapable of understanding some of the basic facts I will try again to enlighten you.
New pump from GPM in Germany has a German made seal cartridge. GPM does not rebuild pumps so rebuilt pumps are rebuilt by a totally different company and they use a different seal cartridge - cheaper and low quality - We sent a number of pumps to GB and he dissected them all - reported on Rennlist - search is your friend.
Every time a WP is rebuilt the fits are compromised. Hence the seal cartridge moving in the casting. Hence the metal impeller's coming off the shaft.
I know of at least 6 different casting used for 928 water pumps - some are good quality and some are not - its a crap shoot what you will get.
Every time someone sends back a core - it could be a cheap Chinese knock off core -so the one you are getting could be really bad.
You asked for advice and then totally disagreed with everything you were told. Why the F**ck did you ask for advice in the first place is beyond my comprehension.

All Porsche parts come from three main warehouses here in the States - Atlanta, Ontario and the North East. The three warehouses are fed from the main warehouse in Stuttgart. Porsche does not make parts their suppliers do.

I only do about $1m of parts business with Porsche so what would I know about how the system works.

All Porsche parts have a warranty of 2 years/24k miles. That warranty is usually only honored providing the parts are fitted by a Porsche dealer. Even if they do honor the warranty they will only replace the part or give you your money back. So $188 will go a long way to replacing the engine in a 928 because of a seized water pump!!!!!!!!!!!!!!!!!!!!

Now that you have advised everyone to use a cheap rebuild I am sure you will cover the cost of engine rebuilding if and when their pump fails 8>(.
I have to believe that most 928 owners are little bit more savvy than you appear to be.

[harborman]

You can bring a horse to water but you can't make it drink. After all is said and done it looks like the final decision will be the cheap, rebuilt pump.

DON'T.

The force/load on the 928 water pump bearing is significant. Unlike most other cars, this bearing is subject to the force/load of the cams translated through the cam gears/sprockets to the belt, and hence the pump's bearing.

I'll answer your subsequent post here and say 'no, you'll have to remove the engine to get the cylinder heads off'.

I don't sell Parts or Push them like many on this site . My Understanding of this is clear push your sales
Warranty is a Porsche Warranty . Porsche Dealer's ( spoke to 3 ) States That the Porsche Factory is the re builder the same one that makes the new Units and the parts are the same . So if you have questions direct them to Porsche .
Porsche Atalanta NA states they do not sell Parts but rather direct you to a dealer
You want to argue then argue with them as they are the one's selling the parts and making the statements . That's why Links are posted ask away .
I doubt Porsche Parts are made in China however feel free to ask them .
Plastic / Composite Type Impellers seem to be the Normal Impeller now from Porsche .
They do not Harm the Block when the bearing fails as far as I have seen .
the 86S I am working on proves that in this instance a 15 year old rebuilt pump with another Bearing gone bad but no damage to the block with the plastic Composite Impeller on it .
I agree that a warranty does not cover other then the Pump itself I wish it did but understand why it does not .
I am not advising anybody to do anything but have a Happy New year. what I do with my own car is my only decision . I don't sell Parts .

So No one has any information on the Porsche bearing part number then
Happiness is where you find it .

aluminum, no one is trying to sell you anything. What a number of people have done is try to help you avoid the very high probability of damaging or destroying your engine. Do a search of rebuilt water pump failures here and on Rennlist. You will discover many examples of failed rebuilt pumps. You keep going back to Porsche dealers for your talking points. The average Porsche dealer knows precisely the square root of zero about 928's. Only about 30,000 928's ever came to the USA. That was from 1978 into 1995. Over those 17 years and nearly 300+/- Porsche dealerships the average Porsche dealer ship might see 10 928's a year, some none, and some more. But, there are virtually no Porsche trained 928 mechanics at any dealer ship today that has any real expertise on 928's, 21 years after the last model came off the assembly lines and 38 years after the first. Some of the folks on this forum and Rennlist are the experts on these cars today. Rog100 owns perhaps 20 928's at any time, he is an official Porsche parts seller, a Porsche aficionado par excellence, and he has spent many thousands of $$$ on rebuilt water pumps that "were professionally done and better than new" and he ended up eating a lot of them when they failed. He does know of what he speaks. He has done the research made the experiments, and paid the piper ultimately. But, as my dad used to say "none are as blind as those who refuse to see."

[MainePorsche]

Not trying to sell you, or anyone, anything. I'm not in that business.
I responded to a 928 forum post about using a cheap rebuilt pump.
For anyone who does, CAVEAT EMPTOR.

[stepson]

Al,
Think of it this way:

What amount would someone have to give you to buy your car when it is running properly?

Now think what someone will give you if the engine gets trashed by using a substandard water pump.

That will be the true cost of the waterpump you end up with.
