b. Lubrication System.
The lubricating oil on the upper parts of new or overhauled engines, and engines which have been in storage,
may not be enough when the engine is started. It is recommended that the upper engine parts be prelubricated by
removing the valve rocker cover and pouring approximately two quarts of the same oil used in the crankcase over the
rocker arms and push rods.
Fill the engine crankcase to the proper level with the Heavy Duty Lubricating Oil specified.
Check the oil level in the crankcase with the dipstick on the side of the engine. Remove the dipstick, wipe the
lower end with a clean cloth, insert and remove it again to check the oil level. Keep the oil at the proper level.
Refer to Lubrication Order Chart for proper lubrication.
c.
Transmission.
Fill the hydraulic marine gear to the proper level with lubricant specified.
d. Fuel System.
Attach a fuel tank. If the unit is equipped with a fuel supply valve, it must be opened.
To ensure prompt starting, the fuel system between the pump and the fuel return manifold should be filled with
fuel. If the engine has been out of service for a considerable length of time, the filter between the fuel pump and the
injectors should be primed. The filter may be primed by removing the plug in the top of the filter cover and slowly filling
the filter with fuel.
In addition to the above, on an engine equipped with a Hydrostarter, use a priming pump to make sure fuel
lines, manifolds, and injectors are full of fuel before attempting to start the engine.
