Removing the valve mechanism
1.
Remove the valve covers.
2.
Remove the DEB or the lubricating-oil strip
(depending on model).

Place numbers on the rocker brackets (a)
and the bridges (2-3-4), to allow
reinstallation in the same position.

Remove the bridges (2-3-4).
Installing the valve mechanism
Note:
In engines equipped with a DEB, the
bridges (2-3-4) of the inlet and exhaust
valves are not the same.
In engines without a DEB, the bridges
(2-3-4) of the inlet and exhaust valves are
the same.
1.
Install the bridges (2-3-4) on the valves.
2.
Adjust the bridges (2-3-4), see chapter
“Checking and adjusting”.
3.
Tighten the rocker brackets (1) by hand.
Note:
Depending on the engine position, some
rocker brackets (1) will have to be
positioned against the pressure of the valve
springs.
The rocker bracket will resist this spring
pressure and can therefore not be
positioned correctly. By cranking the
crankshaft always
