Default The 991GT3 Center Lock Procedure & "Auxiliary Tool"

Pages from the manual:

https://drive.google.com/file/d/0B95...it?usp=sharing

(sorry about the poor scan quality, best I could do with the phone as a PDF maker)

The polygon tool is quite a bit lighter than in the 997.2, and has a new auxiliary tool to remove the wheel-hub caps and make sure the locking pin is fully engaged after tightening wheels. I used to use a plastic trim tool on the caps, and a half inch socket driver to release the locking pin on the .2 car. Progress I guess we now have a tool for both.

Torque is 443 ftlb / 600 nm.

Procedure the same as on the 997 except seems we need to grease and aluminium paste different components every time.

Jacking the car up is a little trickier, the plastic skirts on the side stick out a bit and so youve got to be careful when moving the jack into position.

Loved the line in the manual "Get an authorized Porsche dealer to change the wheel" on page 192. Great if one could come to the track or house each time I want to swap wheels around, tighten them up etc. Those crazy Germans....

Will post a few pics next.

Is the polygon tool 3/4" drive?

So I guess the 997 centerlock socket won't fit the 991 hubs?

As I read it those bolts don't need to be disassembled for greasing??? Heaps less messy than our procedure which is a bonus. Wonder how the internals would remain greased.... hmmmm....

After living with center locks now for 2 years I am not that enthusiastic to try and find a way to upgrade to the new GT3. Maybe one day I will get over it but the center lock procedure really kills it for me when I need to bleed brakes and swap wheels to get ready for a track event.

Amen.

Still need a truck brake pedal depressor tool to do a solo wheel swap which is crazy in a 2014 model year car. Porsche need to wake up.

That battery looks quite large and heavy. I bet you would save some pounds using a smaller one

It looks like they also left themselves an 'out' if you chose to try this yourself. In one place it says "passengers must not be in the vehicle when it is jacked up". But later it says someone must be in the car to depress the brakes. Although I didn't see where it specifically said to tighten with the wheel off the ground - did this change?

They claim the big battery is necessary for the rear wheel steering. RS should have no RWS and small battery.

So as you need a platform due to the high torque forces, then is it impossible to change a flat tire on the side of the road using a regular jack?

Are you SOL if you get a flat tire in this car? Can you use some kind of tire filler gel to get to destination safely if not slowly?

Excellent.

I must have the GT3 fever pretty bad as I just received my Proto 6212 6x torque multiplier.
