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.
