Cylinder head attachment bolts
Cylinder bolts must only be used once. So the 
cylinder 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.
