Laso Water Pumps and other good ones
 

About the Laso Water pumps And Other Water Pumps :
do all laso water pumps have the plastic Impeller that well not damage the Block if they let go ? ( I seem to have read somewhere that the early Laso Pumps had a metal Impeller )
I am seeing some laso Pumps for less then others .
when calling some sellers order desk they don't seem to know . Most are drop shipped so makes it hard to find out .
__________________________________________________ __
What " OTHER " if any New or rebuilt 928 ( for a 1986 Model ) have a plastic impeller if anyone knows .
any Links appreciated.
I Understand that the best pumps have some sort of retaining collar that in case of a " Impeller letting go the collar stops the Impeller from hitting the block .
Any Info on this ? is this info correct or do I have it all wrong perhaps .

probably nobody knows more about these pumps and the questions you are rasing than Roger at 928R Us. Give Roger a call.

My new Laso pump had a metal impeller when I purchased and installed it 3 or 4 years ago.

Laso stopped making pumps for newer 928, still do the older models I think. Pretty much nobody wants to touch a Chinese pump or a rebuilt.

Two big issues; metal impeller moves and machines the block, bearing fails and gets really hot, next stop belt fuses to pulley and breaks on start up.

Talk to one of the known smart 928 vendor, Roger might be the most on top of this, all sell what they have.

Thanks for reply :)
So LASO makes Both metal and ABS or some sort of Most likely high End sort of Plastic .
No Longer for the late models ? so you mean 87 and up correct .
So Lucky Me mine is a 86 Yr Model .
Is not torn down yet I just started and well order after I view how much Damage I Have , Water is leaking out a Bad sign .

Question ? Does LASO Make a Metal Impeller that has a Collar to stop the Impeller should it Brake free .
Ya I well try to find how to Contact Roger to nail down Info
ANY OTHER GOOD PUMPS OUT THEIR ? BEYOND PORSCHE AND LASO ?
Surely Their must be some other Brands that well work with a Plastic Impeller

Merry Xmas All

www.928rus.com is roger. One of the owners makes a modified pump called the Guardian.

Porsche could be really old stock, for sure its very costly.
Laso I think only has the plastic implellers and no clip etc to hold it.

Other pumps are considered by many as junk, at best unknown.

The Guardian water pump.
EGDS (Engine Guardian Design System).
Brilliantly designed double bearing/gear system - if it were to fail it will disengage the pulley so you your belt won't melt and consequently ruin your interference engine. Can also inspect the system without removing the pump - just the center cover. Fair price too.
No affiliation.

Laso changed to the plastic impellor some time ago in line with Porsche. They stopped making the 87 to 95 pump due to low sales volume. They still make the early 77 to 86 pumps with plastic impeller. If it is a Laso with a metal impeller it will be old stock.
Always buy a new pump with a plastic impeller. Only choices are Laso and Porsche on the early style 77 to 86. On the later style there is only one $1000 choice Porsche.
About 18 months ago a new WP came on to the market but unfortunately it has a metal impeller. It is the GEBA pump however in its favor is that it is new. Jury is still out as it is early days but so far so good.
The Guardian pump is also another good choice because it is new and has a pinned metal impeller.
NEVER buy a rebuilt pump.
If the price of a new pump is to good to be true - circa $100 - then run away.

The current consensus is NOT to change the WP every time you change the belt. Providing it is from a know good source and manufacturer, remove it check it and if all good reinstall.

Lot's Of Great Information here Thanks :) not sure what a " Fair Price " is RE : The The Guardian water pump but well contact them and ask ?
SO Water Pump Update : Busy working on My House in Vegas But today I pulled the Pulley , Dampener, The Cam Covers ( Aluminum or pot Metal ) and the Plastic Center Cover .
AS Suspected after Pouring in some water say a Gallon or so Water began running out right under the Water Pump center Pulley . Not in the Clear Yet .
Bought the Car ( 1986 928S ) with this water leak and a Noise coming from the area of the water Pump , A Rhythmical Knock / slapping sound coming from the Center Front of the Water Pump area .
Yes I know the Motor could be Trashed / Damaged Etc :
So the Good news so far is the water seems to be coming from the Pump area Out of area of the front Bearing exactly centered below the Pump Belt drive Pulley . Not the Block IE : a Hole in the Block.
So after I pull the Pump I well see how much Damage the Impeller has done Behind the Pump. I am Holding my Breath on that one humm .
I see this Great write Up for a damaged Block :
928 Block Damaged by Water Pump Repair - Rennlist Discussion Forums
I am seeing the recommended Laso Pump online free shipping for $ 236 is this the best price for this pump if anyone know's and Tips appreciated. Link : http://www.*********.com/nsq2twx-porsche-928-water-pump.html
I also note the Front crankshaft Seal seems to be leaking Oil Like crazy so time to fix that Now also . Hope they just Pop Out without to much strain .

aluminum, do yourself a big favor and call up Roger at 928's r us, (ROG100 above). He may not have the cheapest pump but he has the best support one can ask for. He knows the other things you need to do while the pump is out, what to look for, and what little nitty pieces you will need besides the pump. Just for the record I have purchased pumps from 3 sources, the first one (very early in my 928 days) I bought was because it was cheap. Big time mistake. It was rebuilt, even though the seller claimed it was new. When questioned he said it was "newly rebuilt, same thing." Not quite.... the last one was from Roger, he will get any future business from me on anything he stocks or can get. He is that good at assisting us sorry shade tree mechanics....and that is literally worth a small fortune to me...

[IMG]my photos[/IMG]Removed the Pump today on this 1986 928S

Bearing is shot and Drive Pulley flopping around . Pump is A Rebuilt one has Tag on it says rebuilt by Independent Rebuilder but no Name . Car has records and part number says
928 106 015 KX $139.86 Impeller is Plastic . The Block is just fine but now polished a bit by the plastic Impeller . Their is no Damage at all. Noise was quite loud from the pulley / bearing .
I Have Photos if I can remember how to load on reply ?
So I must create a New Post to load Photos I Guess ? weird Insert Image wants a URL ?
anyone know how to load Photos on reply ?

Not sure what Support from Rodger means ? . I know he uses this site to sell his parts that seem to be the same parts other's sell . His information is good Info and I like that as that's what a forum is for .
My Take on the forum is to Get and Give help . The Best Price on a quality
recommended part is considered Help by Me .
I have given parts away on this site for free . That's also a form of help

I am Glad the Pump I Pulled has a plastic Impeller or the motor would be shot I expect . Its not a laso Pump unless laso Pumps say independent Rebuilder rather then laso
Was Installed in 2001 so that a good run to Now 2015 Cost was $ 139 I have the Receipt in fact came with the car . Intersting back in 2001 they had the Plastic Composite type Impeller for Reasonable cost .
Note a Rebuilt Pump is almost the same as a New Pump in most cases :
It Has a OEM Porsche Core / Case . a new bearing / Seal Impeller / and Drive Pulley . Not much to a Water Pump.

Here's some pics of the EGDS pump.
It's impeller is pinned to the shaft.
It bearing/coupler is designed to shear so as to not lock the pulley in the event of bearing failure. Its bearing is a sturdy double row bearing. Will spare the belt should the unlikely failure occur.
As can be seen it can be inspected with pump attached.
Designed/fabricated by an engineer who is a 928 guy.

I remember a discussion awhile back about modified GEBA pumps, where one of the major suppliers (Roger?) was looking into having plastic impellers retrofitted on to them. Did that ever get done?

I talked to GEBA but they do not see any reason to change to a plastic impeller - bad choice in my book.

LASO listened to the 928 community and changed to a plastic impeller in line with Porsche.

I just purchased 100 LASO 77 to 86 Water Pumps and from January 1st will sell them for $355 each which is pretty competitive.

That's a Great looking pump well have to price check it
 

Wow I Like the look of that Pump , Costly no doubt
I see someone deleted / blocked the *********.com link for there Laso Pump for
$ 236.33 free shipping
Laso W0133-1599439

now that's " Competitive " I would say with the free shipping and all
No doubt you can find it should someone delete / Block the link
No why would a forum block a good water pump with a plastic Impeller just
what a Aluminum Block needs to save the 928 Motor should a Metal impeller
come loose . Sure saved mine that's for sure .

$236 would be the bargain of the century so grab it while you can. Direct from the factory and in a large quantity I paid way more than that.

I searched your link and found some Laso pumps at lower than $355 but they were all re-manufactured - rebuilt - not good.

You give good Information on the 928 Porsche thanks for that .
However ? the laso Pump sells for $236.33 with free shipping .
So some for $225 to $250 seems to be the Norm
Perhaps this well help you with your pricing and the development of
ongoing happy costumers .
Thanks for all the good 928 Info and Merry Xmas.

Aluminium - I guess you did not take the time to read post #17 & #18 and if you can find NEW Laso pumps with plastic impellers for less than $350 then that is a great bargain - OR after I searched found them to be refurbished/re-built/re-manufactured and not new.

If the price seems too good to be true IT PROBABLY IS.

All parts suppliers buy from the same sources and there are about four here in the States plus the factory in Germany for Laso pumps. But what would I know after all I am just a 928 specialist parts supplier 8>)
