4. check
valve clearance
Out of specification
Adjust. Refer to
“ADJUSTING THE VALVE CLEARANCE”
standard value
standard compression pressure data
1200Kpa (12kg/ cm
2
)-1000r/min
5. read the highest data on the compression
pressure meter
·
Above the maximum pressure:
Check the cylinder head, valve surfaces, and
piston crown for carbon deposits.
·
Below the minimum pressure:
Check the accumulation carbon in the
firebox of the cylinder head and
accumulation carbon on the piston head.
·
Refer to the table below.
Compression pressure(with oil introduced
into cylinder)
Reading Diagnosis
Higher than
without oil
Worn or damaged pistons
Same as
without oil
Defective ring(s), valves,
