Fantastic Flywheel Seal Istallation tool. Great stocking stuffer!
The stock flywheel tool (000 721 912 60) is a simple, yet fairly reliable tool.
'
It works very well, as long as it never "tilts" this too while installing the seal (this will, invariably drive one side of the seal too deep and result in the seal not being perfectly "square" to the crankshaft), you are mentally prepared that occasionally the "spring" inside the seal will catch on the edge of the crankshaft (resulting in the spring popping off), you are happy with the depth the tool installs the seal at (varies a bit, depending on the crankcase casting), and you don't have to use this tool in situ (difficult to figure out how to pry or hammer on this rather tall block of plastic, inside the bell housing), and you don't mind the $232 retail price, from Porsche.
If you've ever had to do this job, been one of the dozens who's new flywheel seal leaked, after installation, or are planning on doing this job, there's a new solution. Factory 928/944/911 flywheel tool.
One of my very good lifelong friends son, came up with a rather inventive way to do this job.....better and much easier, both with the engine out of the car and in situ.
They asked me to critique their tool and I made a couple of suggestions, resulting in a couple of different prototypes.
The result is the best flywheel seal installation tool I've tried:
Here's a picture of this tool working, with engine in the car and flywheel removed"
The installation instructions are attached below.
Special introductory "Black Friday" price of $129.95, plus tax (if applicable) and shipping.
You can buy it from me (I have 7 left),

Semi-retired, as of Feb 1, 2023.
The days of free technical advice are over.
Free consultations will no longer be available.
Will still be in the shop, isolated and exclusively working on project cars, developmental work and products, engines and transmissions.
Have fun with your 928's people!
Very cool Greg! I already have the factory one or I'd buy this.
Understand that.
I've struggled with the factory tool, for almost 45 years (first 911 with this size seal was 1978,)
I have no idea how many engines I've had to re-remove to repair a leaky flywheel seal.
I always blamed this on the seal, but I've learned that if the seal is off just a tiny amount (from being perfectly "square" with the crankshaft), the oil gets "ejected" at the high spot.
I had a terrible issue with the Victor Reinz seals which came in the Victor Reinz gasket set. I found another seal, to use, instead of this seal. (Elring.) (The Victor Reinz seal measures 110.35 on the OD and the Elring seal measures 110.15.)
My entire issue, with the Victor Reinz seal leaking, turned out to be the fact that the Victor Reinz seal (a little bit "oversize" on the OD of the seal), which made this seal very diffficult to install without distorting it.
(The difference in installation "difficulty" of the Victor Reinz seal resulted in one update of this tool to make the tool more rigid.)
And even with that, a super slippery fluid (like Wurth HHS, which I believe everyone who works on virtually anything should have a can of) is highly encouraged, when installing the Victor Reinz seal.
I had a giant "stack" of Victor Reinz seals (giant for me...about 25) which I was afraid to install, which I am now installing, using this tool.
Bonjour Greg,
I have the leaking Victor Reinz seal installed… could you add one of this tool to the list of items I sent you for pricing ?
have a great weekend
