2. Attach pressure gauge (B) from JT05470 Universal
24
Pressure Test Kit to oil gallery.
IMPORTANT: To achieve an accurate oil pressure
reading, warm up engine crankcase oil
to 105C (220F) or high oil pressure
readings will occur.
3. Start engine and run at speeds given below.
4. Measure oil pressure and compare readings.
Minimum Oil Pressure-No Load at Slow Idle and 93C (200F) Oil
Temperature--Specification
B--Pressure Gauge
Minimum Pressure............................................ 100 kPa (1.0 bar) (14 psi)
Minimum Oil Pressure-Full Load at Rated Speed and 105C (220F)
Oil Temperature--Specification
Minimum Pressure.......................................... 275 kPa (2.75 bar) (40 psi)
NOTE: Tolerance extremes and gauge fluctuations can
result in the gauge reading up to 586 kPa (5.86
bar) 85 psi. This is not detrimental to the engine.
The oil pressure regulating valve is designed so
that adjustment of oil pressure should not be
required.
5. Replace oil pressure regulating valve if oil pressure is
not within specified range.
