Preparations:
– Remove the cylinder head; see M 07.30.
Dismantling the cylinder head:
– Remove the circlips (89/10) from the
rocker pedestal and pull off the rocker
(89/11) with shim washers (89/12).
– Pull out the centering sleeves (89/1) and
place the cylinder head on its sealing
surface.
Note:
Do not scratch or otherwise damage the
cylinder head sealing face; always place a
soft cloth or similar underlay beneath it.
– Press the spring plate (89/2) down with
tool - 6 - and remove the valve spring
collets (89/3).
– Take out the valve springs (89/4) with
underlay washers (89/6).
Note:
Engines with a running speed of less than
2300 rpm are equipped with adjusting
screws with longitudinal slots for the
rockers (89/13) and valve stem seals
(89/5).
You are recommended to retrofit these
screws during subsequent repair work.
Engines built up to and including 1983 (all
running speeds) have single valve springs.
During repairs you are recommended to
install double valve springs on engines
which run at more than 2300 rpm.
– Place the cylinder head on the exhaust
side and pull out valve cones (89/16
and 17).
– Take off cover (89/7) with sealing ring
(89/8) and take out thermostat (89/9).
