Water is highly over rated - lets just circulate amsoil and the WP bearings will last forever!

Lizard931 · 07-12-2009, 07:43 AM

I will still use the rebuilds.

I've replaced 3 pumps on 3 different cars...all Porsche new. I'm hoping someone comes up with a more secure design before my next WP job.

Where's PorKen on this issue?

I used a Snap-On torque wrench and it was installed correctly with new everything that the belt touched and many things it did not.

For your and my failures, the pumps could have been installed with an impact and the belt could have been at 12.9 belt units and none of that stuff would have a thing to do with the impeller falling off. That's just a damn poor press fit. Laso certainly "changed" their design to compensate....on the "new" version. They use the same impeller and the same bearing, but they put a bushing into the impeller to tighten up the press fit. I'd guess that they have a whole bunch of impellers already machined, discovered they are too loose, and did the logical thing to "save" a few bucks....install a bushing.

I do have the tool done to fix the block. Just waiting for Steve to finish up the inserts and the insert drilling tool. I'll start a thread about this stuff, when it is all done.

Personally I owned and used both 9201 and Kempf tools and the 9201 gave me inconsistent, non-repeatable readings evry time, so I sold it and love the Kempf tool, it works great.

Mine gives me dead on, repeatable readings, we tested my 9201 against three of the Kemph tools and all three of the Kemph tools had different readings.

I can set a belt at 5.0 turn it 720 degrees check it again and it is going to be 5.0.

Not sure what to tell you other than no Pro mechanic that works on these cars that I know uses anything but the 9201 because it is reliable and repeatable.

I have and trust my 9201 tool...but admittedly it's slower to use as compared with the Kemph tool. I've tested three Kemph tools against my 9201 and I had to mark my last Kemph wth a mark just barely aboved the notch. I kept thinkin I was getting bad ones. I use the Kemph for quick checks....but to the mark I filed on the tool..not the center of the factory notch. I think it's pretty well accepted, on S4s, that the proper setting is towards the high end of the notch. Set your belt to the center of the Kemph notch and you'll be running a bit loose. Obviously, it's not enough to make much difference but I think you have more of a safety factor by setting at 5.0 rather than lower.

Kemph and I corresponded on this a few years ago. With no complaints he didn't see the use in changing anything. BTW, the Kemph tool was developed while Kemph had a pre-85 928.

I also compared both gauges to the factory Porsche tool from which the Kemph tool was copied.

Where the 9201 really shines is tensioning the AC ribbed belt.

Glad you like the 9201 I sold you Harvey

Stromius · 07-19-2009, 01:49 AM

I am in process to converting to the Porken Tensioners so I guess I (will) have one surplus Kempf tool...and a tensioner (88) Anyone??

I'm a little slow,Heinrich. I'm just now about to install the belly pan set you sold me! Keep the castoffs coming!

Look on the bright side, you can work a 9201 correctly.
