DETROIT DIESEL 53
Operating Instructions 13.1
Fuel System
Fill the fuel tank with the fuel specified under Diesel Fuel Oil Specifications in Section 13.3.
If the unit is equipped with a fuel valve, it must be opened.
To ensure prompt starting, fill the fuel system between the pump and the fuel return manifold with fuel. If the engine has
been out of service for a considerable length of time, prime the filter between the fuel pump and the injectors. The filter
may be primed by removing the plug in the top of the filter cover and slowly filling the filter with fuel.
Lubrication Fittings

other moving parts and fill the hinged cap oilers with a hand oiler.
Drive Belts
Adjust all drive belts as recommended under Lubrication and Preventive Maintenance in Section 15.1.
Storage Battery
Check the battery. The top should be clean and dry, the terminals tight and protected with a coat of petroleum jelly and
the electrolyte must be at the proper level.
NOTE: When necessary, check the battery with a hydrometer; the reading should be 1.265 or higher. However,
hydrometer readings should always be corrected for the temperature of the electrolyte.
Generator Set
Where applicable, fill the generator end bearing housing with the same lubricating oil as used in the engine.
A generator set should be connected and grounded in accordance with the applicable local electrical codes.
CAUTION: The base of a generator set must be grounded.
