That's the correct procedure. After Step 7 you are supposed to check the measurement between the pulley where the bolt mates and the crankshaft snout.

The 240 ft-lb and 140 degrees tightening is a bear. I just installed mine on an engine I have in a stand. My 24" digital torque wrench was 24" too short! LoL

"Maybe" you should consider replacing the front cover seal(?) But your engine looks pretty clean. Maybe not?
Regarding the front cover - I think I'll let sleeping dogs lie. :cool:
