Clutch ..time for a change ?

[86GT351]

I strongly suggest resurfacing the flywheel with any new clutch replacement.

Correct. This is a must. Just like when you do brakes. Replace or resurface the rotors o there is a perfect mting surface

Ditto. How many miles? (Rear main seal, WYAIT)...

..have a new SACHS flywheel here.. so I will use the new one. Car has 70 k mls on the odometer.
Rear main seal... I have a new one, but if the current one is not leaking... why change a running system. ? Will say ..the OEM Stuff is always way better than the replacement stuff. So I am a little afraid, that I install "new piece " with minor quality.
But you are right... IF there is some oil smear / leak the rear seal must be changed.

Saw a video where they pull the bearing retainer.. to change the oil seal. Looks like a good way to go..

Just to be clear. It is important you measure the preload using the parts you intend to run. If you use the stock flywheel, have it resurfaced and then measure the preload. If you intend to run a new flywheel use it when measuring. The stack height will change with different components. This includes the clutch disc and pressure plate.

@ Midlife Crises. Yes, I understand what your are meaning. Every alternation of the set-up..Flywheel.. Clutch Kit.. a.s.o. will result in a different preload number. And this results in a different shim /spacer thickness.

My biggest concern is the "right " preload number.. i.e looks like 1 inch ( 25.4 mm ) is the number most of the guys are talking about ..

But when I think about the function of the TOB and the working area /space.. I see only 0.43 " (11 mm ) left for the space that is needed if the clutch wears out / the TOB bottoms out. Because the complete working stroke of the TOB is 1.432 " ( 36,43 mm ).

I am also in doubt if I should use the GT 500 master..or stay with a stock ( Sachs ) master...

Now I will go to a machine shop , hoping that they can make me a installation tool for the rear oil seal..

Friend of mine.. has a lathe. . Here is the result , a tool for the installation of the rear main seal.
Made from Teflon...

installed the rear main seal... used the FEL PRO BS40644 ( the PTFE seal, with the Install sleeve )

was a little tricky, because the sleeve wasn´t a real help for the installation. so at the end I finished the job without that "sleeve " HOPE that the seal is sealing...

after the rear main seal was installed, I reinstalled the oil slinger..

tomorrow I will ask the "lathe master " again, if he can reduce my 0.5200 spacer I bought from Summit. With the new flywheel , the new LUK clutch kit, I have a total preload of 0.4649 if I add the 0.5200 spacer - the preload will be 0.9849 .

0.9849” preload would work just fine.
