MAINTENANCE SCHEDULE
Preventive maintenance performed on schedule is
the easiest, as well as the least expensive type of
maintenance. It permits the Maintenance Department to
do work on schedule, rather than at inconvenient hours.
Accessories must have a place in the maintenance
schedule the same as the basic engine, for an accessory
failure may put the engine out of operation.
Consult
accessory
manufacturer
for
maintenance
recommendations.
Actual operating environment of the engine must
govern the establishment of the maintenance schedule.
Some engines operate under rather clean conditions,
some under moderately dusty conditions and others
under severely dusty or dirty conditions; each type of
operation must be analyzed as the maintenance
schedule is established.
Hours of operation, miles [kilometers], or calendar
period as shown on Page291are convenient units of
measurement, and should be used to set up the
maintenance schedule interval basis.
These periods, as
stated, are based on average operating conditions.
The maintenance schedule check sheet is
designed as a guide until adequate experience is
obtained to establish a schedule to meet a specific
operation.
A detailed list of component checks is provided
through several check periods; also a suggested
schedule basis is given for hours of operation, calendar
of time or miles [kilometers] driven.
A maintenance schedule should be established
using the check sheet as a guide; the result will be a
maintenance program to fit a specific operation.
The check sheet shown can be reproduced by any
printer so the forms may be available for use.
The
person making each check can then indicate directly on
the sheet that the operation has been completed.
When
a complete column (under A, B, C, etc.) of checks is
indicated, the engine will be ready for additional service
until the next check is due.
Storage For Engines Out Of Service
If an engine remains out of service for three or four
weeks (maximum six months) and its use is not
immediately forthcoming, special precautions should be
taken to prevent rust.
Contact the nearest Cummins
Distributor for information concerning engine storage
procedures.
IMPORTANT
Cummins Diesel Engines are built by Cummins to
comply with the requirements of the Federal (U.S.) Clean
Air Act. Proper Maintenance of the Engine, which is the
owner operators responsibility, is essential to keep
emission levels low.
This Section sets forth the
maintenance schedule which should be followed.
To prove that you have properly maintained
the Engine you should retain records, such as work
orders and receipts, showing that scheduled
maintenance has been performed.
The maintenance record form on page 292 is for
your convenience.
"A" MAINTENANCE CHECKS
