Porsche 928 Flex Plate Check

- Stan (a.k.a. Mrmerlin) explains how to properly check the flex plate to ensure that the thrust bearing is not being forced forward (causing block damage). The tips in this video apply to all years of the 928 and to both manual and automatic transmissions. Stan also explains how to properly set the clutch stub shaft depth on manual transmission cars. This tech session was held at the 27th Annual 928 Frenzy in September 2023.

We need more tutorials like this from Stan on TH-cam. He's a natural! Thanks Greg
Great tutorial from Stan
I have to say this video helped me immensely, Iv done a lot of reading about this but Im more of a visual person so seeing this with the explanation was so helpful.
Im not familiar with Stan but Id like to see more from him. Does he have a TH-cam channel or website?
200k miles on a 1986 Porsche 928S 32v manual transmission and flex plate has never been checked also my EPDM timing belt is over 20 years old last replaced in 2003 including water pump and rollers however has less than 30k on the belt driven on Sundays and California car always garaged in San Diego. 20w50 non synthetic oil replaced every year.
Major thanks for posting this. I'm at 78k miles on a 89S4 and don't know if this procedure has ever been done. I know my engine mounts need replacing. Should I check my flex plate or do my engine mounts first?
If you have to choose, then checking the flex plate is more important. But if it was my car I would just do them both at the same time. As long as you've got the car up on jackstands, might as well knock out both tasks.
@@greg_nichols Solid advice. Thank you sir.
What does it mean if you can't get the fly wheel to move either direction?
That sounds like a very bad thing. Seized motor due to thrust bearing being pushed into the block would be the worst case scenario.

Hmmm.. not the case.. motor s fine, no metal in the oil, even rear pinch bolt was aligned properly and no damage to it.. just no movement on the fly wheel🤔
It must be something simple, then. For a manual transmission, you'd need to ensure that it was in neutral. Are you using a proper flywheel turning tool like the one shown in the video? It takes quite a bit of force to turn the flywheel because of the engine compression.
@@greg_nichols Hey man, I appreciate you taking the time to respond to my question...You mentioned the car being in Neutral for a manual...which made me think that it may not be any different for an automatic...as soon as I put it in Neutral...I was able to get it to move freely!
Pretty sure it is all good as well...about 6-8 thousandths of an inch ( 0.15-0.20mm ) of movement...just uploaded a video of it here:
