Ah, now I see that Pelican has the key I needed after all.
The FSM (05-215) lists the keys in terms of their correction at the crank, while vendors list them in terms of correction at the cam. This has been confusing me, and now I see I've ordered the wrong key for getting the needed correction (I want 4 degrees at the crank, 2 at the cam).
Now it makes sense to me:
- 0.7mm 621 991 04 67 - 4 degrees at crank, 2 degrees at cam;
- 0.9mm 621 991 02 67 - 6.5 degrees at crank, 3 degrees at cam;
- 1.1mm 621 991 01 67 - 8 degrees at crank, 4 degrees at cam; and
- 1.3mm 621 991 00 67 - 10 degrees at crank, 5 degrees at cam.
Shoulda seen that before! Thanks for the replies, Diesel911.
