Oil Pressure Check; Oil Pressure Test Procedure - Suzuki LT-Z250 Service Manual

OIL PRESSURE CHECK

Check the engine oil pressure periodically. This will give a good indication of the condition of the moving
parts.
% Oil pressure:
Above 30 kPa (0.3 kgf/cm† , 4.3 psi)
Below 70kPa (0.7 kgf/cm† , 9.9 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 tachometer onto the spark plug high-tension
cord.
Remove the oil 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.
