CHECKING COMPRESSION PRESSURE
1. Clean the engine thoroughly, preferably
by steam cleaning.
2. Before cranking the engine, make sure all
operating controls are in neutral, brakes
are set and the wheels are securely
blocked.
3. There are two methods of checking com-
pression pressure - the cranking method
and the engine running method.
NOTE
The
engine must be at operating temperature
for either method used.
A. CRANKING METHOD - Close the needle
valve at the fuel tank. Disconnect all high
pressure fuel lines and leak-offlines bet-
ween injectors. Remove all of the injec-
tors. Refer to the chart on Page 3.
