Clutch... (Français à venir)
There is 4 kind of "clutch Job",
General view (Ford Probe V-6) of a clutch system when the transmission is out, yellow shows the disc, green the Pressure Plate and red is the Flywheel... Removing the release bearing, in most car/van, a simple pull / twist is needed
View of the Pilot Bearing and clutch assembly, it's time to removed the clutch.... all 6 Pressure Plate screws and the 6 Flywheel screws, gently removed the Flywheel (most engine have the same clutch system) On that specific car, "the front release bearing retainer gasket" was leaking, and NOT the rear crankshaft seal...

 
General rear view (Clutch removed)  of the VW aircooled engine, all Westy clutch system are the same, including all Vanagon years, only the disc diameter change on the early model Here is a typical clutch kit....

 

 

 

 
Removal of the rear crankshaft seal, be careful not to scratch anything!!!! Inspect the core surface (yellow) and the crankshaft surface. Make sure the Pilot roller bearing is rolling!!! Red arrow shows the endplay shims...

 

 
Put back the new seal, just tap this one IN with any kind of soft object.... it need to be even with the engine core edge.

 

 

 
Change the flywheel inner O-ring, this one is as crucial as the rear crankshaft seal...Lately, most leak i have seen come from this one..... Grease this one.


 
Grease the flywheel (yellow arrow) where the seal sit, put back the 6 flywheel bolts (Check torque!!!!!....i don't...never did and never will!!!! with the CAREFUL use of an impact gun)
Time to put the new disc IN, you will need a "Clutch alignment tool" (Clutch alignment is critical to installation. Otherwise, expect the transmission to not line up with the pilot bushing). Clutch alignment tool comme with various adapter to fit inside the pilot bearing.... When you are sure that the clutch disc hole is align with the pilot bearing, put back the NEW pressure plate.
Now it's time to screw the 6 screws, begin with any of those but make sure you do them in a crosswise pattern, tighten those one by one, a few turn each until you make the final torque...

 

That's about it....
