Cylinder head assembly

General information

The cylinder head is a single-piece cast iron component. The camshaft is mounted in the cylinder head and

runs in shell bearings. The bearings are pressed into each journal and are lubricated under pressure. Bridge

piece guides have been eliminated as floating valve bridges have been utilised.

Special thermal sleeves manufactured from stainless steel are fitted to the exhaust ports. These reduce the

amount of heat transferred to the cooling system and direct the thermal energy to the turbocharger.

The electronic unit injectors are mounted in stainless steel sleeves which have been pressed into the injector

bores of the cylinder head.

The operations to remove and to fit valve seat inserts and to remove and to fit camshaft bearings are not

included as specialist equipment is required. It is recommended that operators take advantage of the Perkins

service exchange scheme if these procedures become necessary.
