REPAIR INSTRUCTIONS, PART 3

Engine Lubrication System
An oil film coats rotating parts and bearings of an
overhauled engine, but this may not provide
sufficient lubrication when the engine is started
for the first time. Following is the recommended
procedure for providing adequate lubrication.
Do not mix brands or types of lubricants.
Chemical additives may be incompatible and may
contribute to the formation of sludge, acid and
hardening. Failure to heed this caution may result
in severe engine damage.
Usually there are various points on the engine
where a pressure line may be opened, but if no
other is apparent, the oil gauge line may be
disconnected and a pressure tank applied at that
point.
PRIMING THE LUBRICATION SYSTEM
1. Fill the engine crankcase with the specified
quantity of the specified engine oil.
2. Using a pressure prelubricator filled with the
specified oil, prime the engine lubrication
system for a minimum of five minutes.
3. Check the crankcase oil level.
4. If necessary, add oil to reach the FULL mark
on the dipstick.
Do NOT overfill.
Oil Pressure
Fuel System
Before working on or inspecting a vehicle, set
the parking brake, place the transmission in
neutral and block the wheels. Failure to heed
this danger can result in unexpected vehicle
movement and cause severe personal injury
or death.
To avoid potential fire hazard, do not service
any part of the fuel system while smoking or
in the presence of flames, sparks or hot
surfaces, or when working on an operating
engine. Failure to heed this danger can result
in fire which can produce severe personal
injury or death.
Wear adequate protective clothing (face
shield, heavy gloves, apron, etc.) when
working on a hot engine to guard against
burns from direct contact with hot fuel.
Failure to heed this danger can result in
severe personal injury or death.
