Oil Change Intervals of Volvo engine diesel generator
Change interval
Engine lubricating oil protects
components from mechanical wear, deposits and chemically-related damage. In
order for an oil to perform satisfactorily it must be composed of a
high-quality base oil with a number of chemical additives. The base oil
gradually decomposes, the additives are consumed and the oil ceases to provide
the necessary protection. Operating time, or the time during which an oil
fulfils its function satisfactorily, varies depending on lubricating oil
quality and fuel sulfur content. Oil drain intervals may vary depending on fuel
sulfur content and oil grade. Follow the oil change intervals according to the
instructions for the engine concerned in Sales Support Tool, Partner Network,
Technical Data or in the Operators Manual. NOTICE! Oil drain intervals may
never exceed 12 months.
Engine oil - Volvo Drain Specification
In order for extended oil change
intervals to be approved for Volvo Penta diesel engines the lubricating oil
must fulfill the requirements specified in Volvo Drain Specification (VDS). It
is the responsibility of individual oil suppliers to state whether their oil
fulfils VDS requirements in their specifications.
NOTICE! Volvo has provided the
oil companies with the requirements oils must fulfil for extended oil change
intervals to be approved. We would like to point out that it is the
responsibility of the oil companies to ensure that their products meet the
requirements issued by Volvo. AB Volvo Penta bears no responsibility for this
or for any consequences arising from changes in product designations.
Viscosity
Select the viscosity according to
the table. The temperature values refer to stable ambient temperatures.
* SAE 5W/30 refers to synthetic
or semi-synthetic oils.
Oil Temperature and Oil Filter
Oil temperature
Lubricating oil temperatures for
Volvo Penta engines depend on operational circumstances. Check technical data
in Sales Support Tool, Partner Network for each engine.
Full flow filter
Volvo Penta engines are equipped
with full flow lubricating oil filters as standard. These filters are specially
designed for diesel engines in order to cope with flows, temperatures and
pressures in a satisfactory manner and to provide the necessary filtration
capacity. If filter types other than those originally installed are to be used,
they must first be approved by Volvo Penta.
Remote filters
If the regular filter location in
the installation is unaccessible, a remotely-located filter may be used. It can
be ordered as a pre-mounted accessory when purchasing a new engine. Ask Volvo
Penta for advice before relocating filters. This is especially applicable where
filters of a model other than the original are to be used. Take care with the
cylinder block, adapters and pipe runs so that flow directions through the
filter head are correct.
Steeply inclined engines
Refer to the Industrial Sales
Guide for more detailed information.
NOTICE! The inclines specified in
the Industrial Sales Guide are applicable on the condition that the engine is
installed vertically and that the oil volume is between the min and max values. Contact
Volvo Penta if the engine is to be installed on an incline.
Oil Analysis
General
It is important both technically
and economically to choose the right oil for each individual application. The
requirements for a lubricating oil depend not only on the part of the vehicle
in which it is to be used, but also on design and operational conditions. Rapid
developments within engine technology have resulted in a great number of engine
oil specifications. It is the responsibility of the oil producers to ensure
that their products fulfil
different engine specifications. We therefore only recommend the use of
well known brands of oil.
Analysis of lubricating oil from
diesel engines
An oil analysis program is
offered by a number of companies and they can be used to check wear in e.g.
engines and transmissions, and also to check oil condition. The analysis is
carried out at a laboratory where the content of wear metals and other
contaminants is determined. Such oil analyses may only be used as a supplement
to service and maintenance.
Some points to observe regarding
the analysis of engine oils:
The company performing the
analysis supplies information that must be checked and evaluated before any
engine repair work is begun.
Why?
- It is necessary to determine
where the particles (content) come from. Refer to "Tracing particles"
in the Sales Support Tool, Partner Network, Service Bulletin, SB 18-8.8
- Analysis values for comparison
must always come from the same engine.
- A more detailed evaluation must
be based on the internal relationship between the different partial results
(metal content).
Recommended oil sampling
technique:
1 The sample is taken from a
valve in the main oil gallery.
2 The sample is taken with the
aid of an oil sampling kit (syringe, plastic tube and bottle etc.) provided by
most oil companies. Insert the pipe into the oil dipstick tube down to around
the center of the oil volume.
NOTICE! Do not push the pipe all
the way down to the sump bottom and always use clean sampling equipment
(syringe, tube etc.).
NOTICE! Do not take samples from
a cold engine.
Power Take-off
Power output from Front End of
Crankshaft
Power may be taken from the
crankshaft front end for linear loads. The limitation for such power is the
bolted connection between the damper/belt pulley and the polygonal hub. Maximum
permissible torques for each engine range can be found in Sales Support Tools,
Partner Network. There are however several factors to be considered before
installation starts.
