02.4 THE MANIFOLDS
Manifold Loading
A small, light exhaust silencer may be mounted
direct on the manifold, or on a light extension which
must be no more than 152mm (6ins) long.
Heavy exhaust silencers and air cleaners must be
remotely mounted, or mounted on the engine using a
special bracket, and connected by means of flexible
pipe or hose, with no solid extensions between the
manifold and the flexible element.
All joints must be gas tight.
WARNING
EXHAUST GASSES CONTAIN CARBON MONOXIDE
WHICH IS A COLOURLESS, ODOURLESS AND
POISONOUS GAS THAT CAN CAUSE
UNCONSCIOUSNESS AND DEATH.
CAUTION
Detrimental damage to the engine, or loss of performance,
may be caused if exhaust gasses are sucked in by the air
cleaner or the fan.
The exhaust manifold is made of cast iron and the
inlet manifold of light alloy, both are secured to the
cylinder head on studs and nuts which are torque
loaded.
Bolted to the side of the exhaust manifold is the
standard exhaust silencer which has provision for fitting
a tail pipe or a lightweight extension; the outlet of the
silencer tail pipe must face away from the engine.
