Oil Pressure Check; Oil Pressure Test Procedure - Suzuki TU250X Service Manual

OIL PRESSURE CHECK

Check the oil pressure periodically. This will give a good indication of the condition of the moving parts.
 Oil pressure:
Above 30 kPa (0.3 kgf/cm², 4.3 psi)
Below 70 kPa (0.7 kgf/cm², 10.0 psi)
Low or high oil pressure can indicate any of the following conditions:
LOW OIL PRESSURE
* Clogged oil filter
* Oil leakage from the oil passage
* Damaged O-ring
* Defective oil pump
* Combination of the above items
HIGH OIL PRESSURE
* Engine oil viscosity is too high
* Clogged oil passage
* Combination of the above items

OIL PRESSURE TEST PROCEDURE

• Connect the multi circuit tester or engine tachometer to the
high-tension cord. (2-8)
• Remove the oil gallery plug 1.
• Install the oil pressure gauge and adaptor into the main oil
gallery.
• Warm up the engine as follows:
Summer: 10 minutes at 2 000 r/min
Winter: 20 minutes at 2 000 r/min
• After warming up the engine, increase the engine speed to
3 000 r/min (observe the tachometer), and read the oil pres-
sure gauge.
 Oil gallery plug: 23 N·m (2.3 kgf-m, 16.5 lbf-ft)
