You can fast forward to 4:50. If you have ever taken off a CL wheel, the paste is EVERYWHERE.

That video was just setting off crazy heart palpitations. From the wrenches being so close to the body, to the crest tip not aligning with the valve. Nice how he fingered the camera while looking through the tire size...

For anyone that has CL wheels, please refer to the 20+ page pdf that was attached to a thread about centerlock. This is a Porsche document and tells you what to do and what not to do. This is a MUST read for centerlock wheel owners. Do not refer tot this video.

If you don't have Optimoly, smear a little Vaseline on the hub flanges in Rich's diagram above. Does the same thing. Fingertip or Q-tip.

What is the recommended torque for the bolts on NON center lock Porsche wheels?
Is 140 Nm correct?

Speed2k

118 ft-lb or 160 Nm



Saved from another thread I read through before.

Vaseline vaporizes at about 100 F, Optimoly is the only acceptable lube.

I couldn't find any pdf on Rennlist about the exact detail of application of anti-seize on center lock hubs, but, as I understand it, you do put anti-seize on the hub threads and the conical (trapezoidal) portion of the center lock nut. You can put anti seize on the center lock threads because there is a locking pin, which prevents the nut from loosening. You do not want to use anti-seize on the standard lug nuts, as that will affect torque, and potentially allow them to loosen with use.

I ordered replacement center lock nuts for my GT3 RS (due to track mileage), and they arrived this week directly from the German factory, boxed and wrapped. I unwrapped one nut, and it arrived with the Optimoly anti-seize paste already applied. The paste was applied to the conical surface, as well as the threads (which would thread onto the hub) See photo below.

For anyone that has CL wheels, please refer to these Porsche documents. Read them and lube what they say to lube. Don’t lube what they say not too. Torque to spec with wheels off the ground.

Thanks for sharing this!

From my cursory review, the only divergence of opinion between the video above and this document is: 1. do not have wheels touching the ground during torque application, and 2. no need for anti-seize paste on the splines of the center lock nut (that comes in contact with the locking pin).

Both recommend anti-seize paste on the threads of the hub and central bolt. (The Porsche document calls these threads the trapezoidal threads, after their shape when viewing the thread at a perpendicular cross section.)
