Cylinder Block

Illustration 12

g02323355

Typical example

The cast iron cylinder block for the 1106A-70T,
1106A-70TA, 1106C-70TA and 1106D-70TA engines
have six cylinders which are arranged in-line. The
cylinder block is made of cast iron. The cylinder block
provides support for the full length of the cylinder
bores. The cylinder bores are machined into the
block.

The cylinders are honed to a specially controlled
finish in order to ensure long life and low oil
consumption.

The cylinder block has seven main bearings which
support the crankshaft. Thrust washers are installed
on both sides of number 6 main bearing in order to
control the end play of the crankshaft. The thrust
washers can only be installed one way.

Passages supply the lubrication for the crankshaft
bearings. These passages are machined into the
cylinder block.

Cooling passages are cast into the cylinder block in
order to allow the circulation of coolant.

The cylinder block has a bush that is installed for the
front camshaft journal. The other camshaft journals
run directly in the cylinder block.

The engine has a cooling jet that is installed in the
cylinder block for each cylinder. The piston cooling jet
sprays lubricating oil onto the inner surface of the
piston in order to cool the piston.

A Multi-Layered Steel (MLS) cylinder head gasket is
used between the engine block and the cylinder head
in order to seal combustion gases, water, and oil.

Typical example

(1) Valve keepers
(2) Valve spring retainer
(3) Valve spring

The engine has a cast iron cylinder head (4). The
lower part of the inlet manifold is integral within the
cylinder head. There is one inlet valve and one
exhaust valve (5) for each cylinder.

The ports for the inlet valves are on the left side of the
cylinder head. The ports for the exhaust valves are on
the right side of the cylinder head. The valve stems
move in valve guides that are pressed into the
cylinder head. There is a renewable oil seal that fits
over the top of the valve guide.
