12.3 Oil leak check
Important
•
Before proceeding with operation, read Par. 3.3.2.
Check that there are no leakages next to area
A
.
1.
Start the engine at idle speed or without a load and
check whether there are any leakages next to area A.
2.
It is anyhow necessary to also check the seals of all
main components and their surface contact, such as:
- crankcase and oil seal (side 1
a
PTO)
- oil sump and exhaust caps
- cylinder head and its assembled components
- roc
ker arm cover
- T
iming system carter and oil seal (side 2
a
PTO)
- oil dipstick housing or rod support tube.
NOTE:
Perform the checks described in
Points 1 and 2
periodically and during maintenance procedures.
It is also necessary to check for leakages on the components
that are not listed.
If necessary, disassemble the components that have a leakage
and investigate the possible cause.
The components must be replaced otherwise they do not
guarantee their sealing.

12.4 Oil pressure check
1.
Insert a thermocouple instead of the oil dipstick A.
2.
Unscrew and remove the oil pressure switch B an
d
s
crew on a 10 bar pressure gauge in its seat (Fig.
12.8).
3.
Start the engine at idle speed and without a load,
check the oil pressure value according to the oil
temperature (Fig. 12.7).
NOTE
: The graph in
Fig. 12.7
illustrates the pressure line with
speed of 1000 Rpm.
4.
If the pressure values are below the values indicated
in Fig. 12.7, check to identify the cause of th
e
pr
oblem.
