3.2.5 Exhaust System

Excessive back pressures to the engine exhaust can
considerably reduce both engine performance and life.
It is important that exhaust systems are the proper
diameter, as short as possible, and with a minimum of
bends. Refer to Installation & Operating Data (See
www.clarkefire.com) for exhaust data. Also refer to
the table below for maximum exhaust restrictions.

The installation of the exhaust system should consist of
the following:

Personnel protection from hot surfaces.

Adequate supports to prevent strain on the
engine exhaust outlet and minimize vibration.

Protection against entry of water and other
foreign matter.
While the engine is running inspect exhaust pipe outlet
outside of the pump room itself for environmental
hazards such as excessive smoke conditions.
following could be used as a guide for general engine
operating conditions.
1) Blue Smoke
consumption.
2) White Smoke – Possibility of water in
cylinders, water in fuel or internal engine
problem.

3.3 LUBRICATION SYSTEM

3.3.1 Checking Sump Oil

Check the sump oil level using the dipstick on the
engine as shown in Figure #16.
This level must always be between the dipstick marks
Min. and Max. with the engine not running.
