Z Series E86 M coupe (S54) COUPE
Remove special tool 11 9 170 on left and right sides.
Important!
Make sure that radial piston pump is aligned to driver on
spline hub.
When the left and right screws are tightened down alternately,
the exhaust and inlet camshafts must not rotate.
If the camshafts do rotate, this means that the screws on the
VANOS gear were not previously released correctly.
Alternately tighten down bolts in 1/2 turn increments carefully and
evenly until VANOS adjustment unit rests against timing case
cover.
Insert remaining screws and tighten down.
Note:
Use special tool 11 7 200 to tighten down bolts on VANOS gear.
