OVERHAUL CRITERIA
EN0110601H300002
FACTORS TO DETERMINE THE ENGINE OVERHAUL
1.
LOW COMPRESSION PRESSURE.
(1)
Before measurement
a.
Charge the battery completely.
b.
Set the valve clearance to the correct value.
c.
Idle the engine (Coolant temperature at 80
C {176
F}).
d.
Remove the air cleaner.
e.
Remove all injectors.
(2)
Measurement
a.
Insert the gauge adaptor into the nozzles.
SST:
Compression gauge adaptor (A) (S0955-21110)
Compression gauge adaptor (B) (S0955-21030)
Compression gauge adaptor (B) (S0955-21060)
b.
Run the engine with the starter and measure the compression
pressure.
NOTICE
Do not operate the starter for more than 15 seconds.
c.
Measure the compression pressure of each cylinder.
NOTICE
Do not allow gas leakage from the seal face.
(3)
Reassemble the removed parts.
2.
ENGINE OIL PRESSURE.
(1)
Check the oil pressure warning lamp when the oil and coolant temper-
ature is hot [about 80
C {176
F}].
a.
If the warning lamp lightens, check the oil level.
b.
Check oil deterioration.
If oil quality is poor, replace with a suitable grade oil.
c.
Remove the oil pressure switch and install the oil pressure gauge.
