Cylinder block assembly

General description
The cylinder block is made of cast iron and provides
a full length support for the dry liners which are also
made of cast iron. Production liners are a press fit in
the block. In service two liners are available:
! A finished liner, which has a transition fit in the
parent bore.
! A partially finished liner, which is an interference fit
in the parent bore and must be machine finished
after it has been installed.
All liners are honed with silicon carbide tools to a
controlled finish to ensure long life and low oil
consumption. The cylinder liners have a flame ring
above the flange. A bush is fitted in the cylinder block
for the front camshaft journal and the other camshaft
journals run directly in the block.
Engine types AR and AS do not have cylinder liners
fitted and the cylinder bores must be machined
oversize to correct a worn cylinder bore, refer to the
data and dimensions at the end of this section for
further details.
Note: Short engines are also available.
Your Perkins distributor has specialist equipment and
personnel with the correct training to repair worn
cylinder bores.
