Installing the clutch onto the crankshaft required attention to few details that, if overlooked, would ruin "start-up" day. The first consideration was the choice of bolt length. The bolt holes in the crankshaft flange run straight through to the interior of the engine block. There's very little clearance between the backside of the crank flange and the bearing web on the inside of the engine, so precise measurements were needed to ensure the bolts did not bottom out on the bearing web. The second consideration was that sealant was needed on the bolt threads to keep oil from wicking up the bolt holes and spoiling the clutch:
The bolts were then tightened using an angle measuring gauge according to the shop manual:
Next up was wiping down the flywheel with lacquer thinner to remove greasy fingerprint residue, and installing the clutch disk. A centering tool is used to hold the disk in place while the pressure plate is slipped on:
Here the pressure plate is being torqued to specs:
As the pressure plate is tightened, the spring fingers gradually retract and flatten out. Here's a close-up:
And here are a couple wide angle photos showing the completed clutch assembly on the engine:
