PRACTICES
Left and Right Sides of the Engine
Throughout this section, the left or right side of the
engine is as viewed from the flywheel end.
Cleanliness
Cleanliness is very important during engine repair. Con-
tamination of the engine during repair will reduce the life
of an engine. Thoroughly clean the engine and engine
compartment area before attempting to service or repair
the engine.
DO NOT steam clean the following parts:
• Electrical Components
• Wiring
• Injectors
• Fuel Pump
• Belts and Hoses
• Bearings
During reassembly and inspection, thoroughly clean all
parts, and, where present, remove burrs and scales.
Gaskets and O-rings
NEVER re-use a gasket or O-ring. Use new gaskets and
O-rings. Thoroughly clean sealing surfaces before install-
ing a new gasket or O-ring. Always install new flat-faced
O-rings when servicing hydraulic fittings. Cover any open
ports of high-precision components (such as fuel system
equipment) exposed by removal or disassembly to help
prevent the entry of foreign material.
Capscrews and Metric Parts
When replacing capscrews, always use a capscrew of
the same size and strength as the capscrew being
replaced. Incorrect capscrews cause engine damage.
Return capscrews removed from the engine to their origi-
nal locations.
The Perkins 1004 series engine uses parts that are of
metric dimensions. Metric capscrews are described, in
millimeters, in terms of major thread diameter, distance
between threads, and overall length.
Metric capscrew dimensions:
Verify that the correct type of part is used at all times.
8A.5 PERKINS ENGINE COOLING SYSTEM
The Perkins engine cooling system is a closed, pressur-
ized system that consists of coolant passages in the
engine, plus the oil cooler, thermostat, water pump,
hoses, radiator and radiator overflow bottle. The engine
is cooled by the circulation of coolant through passages
in the cylinder block and head. Circulation is by thermo-
siphon action, assisted by an impeller-type water pump,
driven by a fan belt from the crankshaft pulley. The water
pump bearings are prepacked with a special grease and
do not require service. Replace a faulty water pump.
General engine cooling specifications and maintenance
procedures are listed in
Section 2 General Information,
Specifications, and Maintenance Instructions
