Preventive Maintenance - Volvo EC330B Operator's Manual

General information

Preventive maintenance

To retain the dependability, noise level and exhaust emission con-
trol performance originally built into your conventional non-road
engine, it is essential that the non-road engine receive 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 sulphur 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.
In cold weather conditions, below 32 °F (0 °C), the use of lighter
distillate or higher cetane level fuel are recommended(final boiling
point max. 660 °F (349 °C) and cetane min 45.)
To avoid excessive deposit formation and to minimize the emis-
sions of sulphur dioxide into the ambient air, the sulphur content of
the fuel should be the lowest available. The diesel fuels recom-
mended for use in Volvo engines should meet ASTM designation:
D975 No. ID (C-B) or No. 2D (T-T); with a cetane level above 42
and sulphur content not exceeding 0.5 percent by weight.
Check for fuel leaks (with the engine running at fast idle):
• Visually check unions and hose connections.
Check the condition of the fuel hoses for:
•
Aging
•
Cracks
•
Blisters
•
Scuffing
Check the condition of the fuel tank:
•
Drain water condensation
•
Check for cracks
•
Check for leaks
•
Check the mounting
Check the turbocharger:
•
Visually check for leaks in the intake hoses and exhaust pipe of
the turbocharger.
