Any recommendations on a pilot bearing puller that you've used before? I would rather buy a tool than improvise. I can always take a chance on buying one, but if someone has experience with one that they used on the 928, that would be great.
get a longer 8mm bolt and nut,
put a lil grease on the threads,
put the nut on the bolt and screw it up about 10 threads,
then put the nut through the pilot bearing then fit a 5 or 6mm allen wrench into the pilot hole, this will hold the nut ,
Now you will turn the bolt,
as the bolt is turned the nut will begin to push the bearing out of its bore.
I stuffed bread in the pilot hole and used a hammer and a manual trans short shaft... you could do this in the car and a pry bar to push the short shaft into the bearing. look on youtube.
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!
Gentlemen, thank you for the recommendations. I ordered the puller that Sean linked to. I checked out the Snapon version, but at over $200 it crossed the single job tool threshold for me on this particular project.
The bolt method is my backup, but I like having the right tools for a job. They always end up coming in handy in the future.
Greg, I called and emailed your shop yesterday. Looking forward to the new parts!
Sterling, I've done the "fill the cavity with grease and insert a reasonably tight fitting bolt or dowel and smack it with a hammer" method before. Worked great as well. Jeannie at 928SP is the one who taught me that! LOL.

I tried that too but couldn't get it to work. Probably operator error.
I just did one on a tool (not the car) and the trick on mine was that the punch had to be very snug to the inner bore of the bearing.
One YouTube video showed using greasy paper towels, so that they wouldn't push out through the bearings, if there is no shield inside the bearing.
The hydraulic method did not work for me abd I didn't know about the bolt method so I used a thing we know as "keilbout" in the Netherlands. It expands on compression so you can pull the bearing out. https://images.app.goo.gl/djuoRPhoqkguPYPd7
I received the tool today and it worked great. Except...the main bolt is too long to be able to fully remove the pilot bearing while in the car. It hits the drive shaft. So, I cut about an inch off of the end of the bolt, which gave it enough room to fully remove the pilot bearing in the car. No flexing, it worked really well. Great recommendation.
Photo of the tool in the car is below, before cutting the main bolt shorter.
