IMPORTANT: These instructions cover only the
routine maintenance of the engine. Refer to your
Cummins Engine Distributor for engine diagnosis,
repair and component replacement.
A gradual running in of a new engine is not
necessary. Full load can be applied to a new
engine as soon as the engine is put into service
and the coolant temperature is at least 140 °F
(60 °C). Extended light load operation during the
early life of the engine is not recommended. Do
not run engine at high no load speeds. Do not
apply an overload to the engine.
8B.1 DISCLAIMER AND SCOPE
OF THESE INSTRUCTIONS
These instructions are written for world wide use.
In territories where legal requirements govern
engine smoke emission, noise, safety factors, etc.,
then all instructions, data and dimensions given
must be applied in such a way that, after servicing
(preventive maintenance) or repairing the engine,
it does not contravene the local regulations when
in use.
8B.3 ENGINE MAINTENANCE
8B.3.1 Left and Right Sides of Engine
Throughout this section, the left or right side of the
engine is the side of the engine when viewed from
the flywheel end.
8B.3.2 Maintenance Intervals
Your engine will require maintenance:
• daily before operation
• every 250 hours or three months
• every 500 hours or six months
• every 1000 hours or annually
Use shorter intervals if ambient temperature is
consistently below 0 °F (–18 °C), above 100 °F
(38 °C), if frequent stops are made or if you are
operating in a dusty environment. Consult your
engine distributor for recommended intervals.
8B.2 STANDARD PRACTICES
Cleanliness is very important during the repair of a
diesel engine. Contamination of the engine during
repair will reduce the life of an engine.
Gaskets will be replaced and gasket faces will be
cleaned, where applicable.
In reassembly and inspection, all parts are to be
thoroughly cleaned, and where present, burrs and
scales are to be removed.
Any open ports of high precision components such
as fuel system equipment, exposed by removal or
disassembly, will be covered until reassembled to
prevent the entry of foreign material.
The B Series engine uses parts that are of metric
dimensions.
Always use caution to be sure that capscrews from
the engine are put back in their original locations.
When replacing capscrews, always use a capscrew
of the same size and strength as the capscrew
being replaced. Incorrect capscrews can result in
engine damage.
Metric capscrew nomenclature:
M8 X 1.25 - 25
Distance between threads in millimeters
Major thread diameter in millimeters
Length in millimeters
