The following picture clarifies David’s point. The mounting holes of the hardy disk are directional and marked with an arrow that should point towards the respective mounting flange. I have marked the arrow by outlining it in blue.
The repair microfiche explicitly mentions this point, but for some reason, I missed the instruction whilst installing it in April 2008. Thanks Davidoli for pointing me to this. Furthermore; another member pointed me to the missing washer plates. Although it is a fact that washers prevent strain on the hardy disk itself, neither the parts catalogue nor the repair instructions mention that washers should be installed.
Next to this corrective measure, I finished some minor points like the pulley on the PAS-pump and the reconnection of the power steering hoses to the pump. The pulley still is the same part as before, but I had it sandblasted, galvanized and powder coated.
I have set a milestone for the end of October after which a temporary change in my private situation forces me to temporarily halt the work on #231. I have known this since last summer, but I have included this break in my planning Anyhow, the milestone is to finish all the required work that is needed to remove #231 from my four-column lift.
Still to do for reaching this milestone:
1: Install main heat-shield between the exhaust manifold and the right front chassis-beam.
2: Install the oil-filter head and replace its oil-pressure switch.
3: Reconnect the oil-cooler to the oil-filter head.
4: Fill engine with break-in oil (15W40 mineral) with new filter.
5: Find a new spanner-rail for the AC-pump (potential showstopper for the milestone).
6: Install the clutch-slave cylinder and the sensors on the gearbox.
7: Connect the reverse gear wiring-loom to the gearbox
8: Install the exhaust system.
9: Torque the sub-frame-and suspension bolts to specification.
10: Installation of the radiator.
I think this can be done in about two evenings.
