Oil Pressure - Suzuki DF 60 Service Manual

OIL PRESSURE

Oil pressure (at normal operating temp.):
420 – 490 kPa (4.2 – 4.9 kg/cm
at 3000 r/min.
NOTE:
The figure shown above is guideline only, not absolute service
limit.
If the oil pressure is lower or higher than the specification, the
following causes may be considered:
Low oil pressure
• Clogged oil filter
• Leakage from oil passages
• Defective oil pump
• Defective oil pressure
regulator
• Damage O-ring
• Combination of above items
TEST PROCEDURE
1. Check the engine oil level.
2. Remove the starboard side cover.
3. Remove the plug for oil pressure service port A.
4. Install the pressure gauge and the adapter into the port A.

6. Warm up the engine as follows:
Summer : 5 min. at 2000 r/min
Winter : 10 min. at 2000 r/min
7. After warming up, shift into the forward gear and increase
the engine speed to 3000 r/min, then compare the pressure
indicated on the gauge to the specifications.
8. Reinstall parts removed earlier.
