Cylinder head attachment bolts
Cylinder head bolts must only be used once. So 
the cylinder head bolts must always be replaced. 
The thread of the new cylinder head bolts is 
provided with a red/brown sealant.

Note:
-

Due to the sealant used on the cylinder head 
bolts, the untightening torque of the cylinder 
head bolts can be substantial!

-

All M16 and M12 threaded holes must be 
carefully cleaned using a screw tap prior to 
the mounting of the bolts.

-

After tightening of the bolts with the 
appropriate tightening torque, the angular 
displacement of the M16 bolts must 
immediately be started.

-

The sealant cannot be applied later.

Tightening cylinder head attachment bolts

Note:
Underneath the bolt head, apply a drop of oil on 
the bearing surface of the bolt heads. Sealants 
also reduce the frictional resistance, which 
means that you must not apply any oil to the 
thread.

(1) Apply a drop of oil to the bearing surface of the M16 and 

M12 bolt heads.

Timing gear

(1) Use Loctite 243 to secure
(2) Apply a drop of oil to the attachment bolts and tighten 

evenly.
