16 The USA Federal Clean Air Act
Preventive Maintenance Program
To retain the dependability, noise level and exhaust emission
control performance originally built into your conventional non-
road engine, it is essential that the non-road engine receives
periodic service, inspections, adjustments and maintenance.
Fuel system
Fuel Recommendations:
The fuel used must be clean, completely distilled, stable and non-
corrosive. Distillation range, cetane level and sulfur content are
most important when selecting fuel for optimum combustion and
minimum wear.
Engine working conditions and ambient temperature influence the
selection of the fuel with respect to cold handling properties and
cetane levels.
If the machine is to operate in cold weather conditions, below
32 ºF (0 ºC), the use of lighter distillate or higher cetane level fuel
are recommended. (Final boiling point max. 660 ºF (349 ºC) and
cetane min. 45).
To avoid excessive deposit formation and to minimize the emissions
of sulfur dioxide into the ambient air, the sulfur content of the fuel
should be the lowest available. The diesel fuels recommended for
use in Volvo engines should meet ASTM designation: D 975 No. 1D
(C-B) or No. 2D (T-T) with a cetane level above 42 and sulfur
content not exceeding 0.05 percent by weight.
Check for fuel leaks (while the engine is running at fast idle):
Q
Visually check unions and hose connections.
Check the condition of fuel hoses for:
Q
Ageing
Q
Cracks
Q
Blisters
Q
Scuffing
Check the condition of the fuel tank:
Q
Drain water condensation.
Q
Check for cracks.
Q
Check for leaks.
Q
Check the mounting.
Check the turbocharger:
Q
Visually check for leaks in the intake hoses and exhaust pipe of
the turbocharger.
