Installing

Note

♦

Always renew cylinder head bolts.

♦

In cases of repair carefully remove gasket remains from cyl‐

inder head and cylinder block. Ensure that no long scores or

scratches are created. When using abrasive paper do not use

a grade less than 100.

♦

Carefully remove remains of emery and abrasives.

♦

Do not remove new cylinder head gasket from packaging until

it is ready to be fitted.

♦

Handle gasket very carefully. Damage to the silicone coating

or the indented area will lead to leaks.

– Turn crankshaft to TDC marking before fitting cylinder head.
– Turn crankshaft opposite engine direction of rotation until all

pistons are approximately equally placed below TDC.

– Fit cylinder head gasket.

– Operate starter until tester shows no further pressure in‐

crease.

Compression pressures:
New: 25...31 bar, wear limit: 19 bar
Maximum permissible difference between all cylinders: 5 bar

Note

If ceramic glow plugs are fitted, always observe notes on remov‐

ing and installing ceramic glow plugs

tension and socket -3220- .

Specified torque: 15 Nm.
– Read fault memory of engine control unit.
