*BE01.30-N-1002-02C

If the cylinder head (2) is warped or cracked, or if the cylinder head gasket (1) is not gastight,

it is advisable to replace a cylinder head without inductive hardening with a new cylinder head with inductive hardening. In the case of a cylinder head with inductive hardening, the cylinder head (2) must be replaced.


If the cylinder head (2) is replaced,
the cap and the piston for the constant throttle must be modified.
Replace the O-ring on the cap and check the sealing ring on the piston for wear or damage; replace the piston if necessary.

21

Clean and check the contact surfaces of the cylinder crankcase and of the cylinder head (2)


No dirt must find its way into the bores for engine oil, coolant, push rods (5), cylinder head bolts (8) or the cylinder liner.
Otherwise, engine damage can occur.

Only scrape off sealant and paint residue from the contact surface, do not rub it with an emery cloth.

22

Check cylinder head bolts (8)

If the permissible shank length (L) is exceeded, the cylinder head bolt (8) involved must be replaced.

23

Check dowel pins (14) for damage.

If a dowel pin (14) is damaged, both dowel pins (14) must be pulled out with a pliers and replaced with new dowel pins (14).

24

Pull stop plug carefully out of all bores of the cylinder crankcase

25

Check the seat of the roller tappets in the cylinder crankcase
