On the flywheel is engraved the reference infor-
mation UP TDC, DOWN TDC and the angle in-
dications listed in the table below. Depending on
the engine installation, this information is visible
in one of the windows, either furthest up or fur-
thest down on the flywheel. See illustration.

1. Clean the rocker covers and the area around
them.
2. Remove the rocker covers.
3. Use the turning tool appropriate to the instal-
lation of the engine. Tool 99 309 (or equiva-
lent from other suppliers) is used to rotate the
flywheel from the underside of the engine
and tool 2 402 509 (or equivalent from other
suppliers) is used from the top side.
4. Start adjusting one cylinder according to the
table. Rotate the flywheel until the correct
engraving can be read on the flywheel. It
may be necessary to rotate it more than 1 rev-
olution.
Rotate the flywheel in the rotational direc-
tion of the engine, which is clockwise
