3. Oil Pressure Measurement
Service standards
Tightening torque (Unit: N·m {kgf·m})
Lubricant and/or sealant
• Remove the engine oil pressure switch.
• Using an adapter, connect an oil pressure gauge to the engine
oil pressure switch mounting hole.
• Warm up the engine until the oil temperature reaches 70 to
90°C.
• Measure the oil pressure while running the engine at a minimum
speed and then at maximum speed, both under no load.
• If the measurements are below the specified limits, overhaul the
lubrication system.
• After taking the measurements, install the engine oil pressure
switch using the following procedure:
• Cool the engine adequately so that the engine oil pressure
switch can be tightened with an accurate tightening torque.
• Apply sealant to the threaded portion of the engine oil pres-
sure switch.
• Tighten the engine oil pressure switch to the specified torque.
