Literature Information
This manual contains safety, operation instructions, lubrication and maintenance information. This manual should be stored in or near the engine area in a literature holder or literature storage area. Read, study and keep it with the literature and engine information.
English is the primary language for all Perkins publications. The English used facilitates translation and consistency.
Some photographs or illustrations in this manual show details or attachments that may be different from your engine. Guards and covers may have been removed for illustrative purposes. Continuing improvement and advancement of product design may have caused changes to your engine which are not included in this manual. Whenever a question arises regarding your engine, or this manual, please consult with your Perkins dealer or your Perkins distributor for the latest available information.
Safety
This safety section lists basic safety precautions. In addition, this section identifies hazardous, warning situations. Read and understand the basic precautions listed in the safety section before
operating or performing lubrication, maintenance and repair on this product.
Operation
Operating techniques outlined in this manual are basic. They assist with developing the skills and techniques required to operate the engine more efficiently and economically. Skill and techniques develop as the operator gains knowledge of the engine and its capabilities.
The operation section is a reference for operators. Photographs and illustrations guide the operator through procedures of inspecting, starting, operating and stopping the engine. This section also includes a discussion of electronic diagnostic information.
Maintenance
The maintenance section is a guide to engine care. The illustrated, step-by-step instructions are grouped by service hours and/or calendar time maintenance intervals. Items in the maintenance schedule are referenced to detailed instructions that follow.
Recommended service should be performed at the appropriate intervals as indicated in the Maintenance Interval Schedule. The actual operating environment of the engine also governs the Maintenance Interval Schedule. Therefore, under extremely severe, dusty, wet or freezing cold operating conditions, more frequent lubrication and maintenance than is specified in the Maintenance Interval Schedule may be necessary.
The maintenance schedule items are organized for a preventive maintenance management program. If the preventive maintenance program is followed, a periodic tune-up is not required. The implementation of a preventive maintenance management program should minimize operating costs through cost avoidances resulting from reductions in unscheduled downtime and failures.
Maintenance Intervals
Perform maintenance on items at multiples of the original requirement. We recommend that the
maintenance schedules be reproduced and displayed near the engine as a convenient reminder. We also recommend that a maintenance record be maintained as part of the engine's permanent record.
Your authorized Perkins dealer or your Perkins distributor can assist you in adjusting your maintenance schedule to meet the needs of your operating environment.
Overhaul
Major engine overhaul details are not covered in the Operation and Maintenance Manual except for the interval and the maintenance items in that
interval. Major repairs should only be carried out by Perkins authorized personnel. Your Perkins dealer or your Perkins distributor offers a variety of options regarding overhaul programs. If you experience
a major engine failure, there are also numerous after failure overhaul options available. Consult with your Perkins dealer or your Perkins distributor for information regarding these options.

Engine Cooling and Lubrication
The cooling system consists of the following components:
•Gear-driven water pumps
•Water temperature regulators which regulate the engine coolant temperature
•Gear-driven oil pump (gear type)
•Oil coolers
The engine lubricating oil is supplied by a gear-driven pump. The lubrication oil is cooled and filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine parts when oil viscosity is high. Bypass valves can also provide unrestricted flow
of lubrication oil to the engine parts if the oil filter element should become plugged.
Engine efficiency, efficiency of emission controls, and engine performance depend on adherence to proper operation and maintenance recommendations.
Engine performance and efficiency also depend on the use of recommended fuels, lubrication oils, and coolants. Refer to this Operation and Maintenance Manual, “Maintenance Interval Schedule” for more information on maintenance items.

Engine Lifting
NOTICE
Never bend the eyebolts and the brackets. Only load the eyebolts and the brackets under tension. Remember that the capacity of an eyebolt is less as the angle between the supporting members and the object becomes less than 90 degrees.
To remove the engine ONLY, use the lifting eyes that are on the engine. If necessary, remove engine components in order to avoid damage from the lifting device.
Lifting eyes are designed and installed for specific engine arrangements. Alterations to the lifting eyes and/or the engine make the lifting eyes and the lifting fixtures obsolete. If alterations are made, ensure that correct lifting devices are provided. Consult your Perkins dealer or your Perkins distributor for information regarding fixtures for correct engine lifting.
i03781209
Engine Storage
When it is necessary to remove a component at an angle, only use a link bracket that is properly rated for the weight.
Refer to Perkins Engine Company Limited, Stafford, ST16 3UB for information on engine storage.
There are three different levels of engine storage. Level “A, B and C”.
Level “A ”
Level “A” will give protection for 12 months for diesel engines and for gas engines. This level is used for engines that are transported in a container or by a truck.
Level “B ”
This level is additional to level “A”. Level “B ” will give protection under normal conditions of storage from −15° to +55°C (5° to 99°F) and “90%” relative humidity, for a maximum of 2 year.
Level “C ”
This level is additional to level “B”. Level “C” will give protection for five years in tropical or in arctic climates. Level “C” also meets MOD NES 724 Level “J” for Europe, when engines are stored in an unheated building or in the open under a waterproof cover.
Illustration 15 |
