Suzuki GSX-R. Engine lubrication symptom diagnosis


Oil pressure check

Check the engine oil pressure periodically. This will give a good indication of the condition of the moving parts.

Note

before checking the oil pressure, check the following.

  •  Oil level (refer to engine oil and filter replacement in section 0b .)
  •  Oil leaks (if leak is found, repair it.)
  •  Oil quality (if oil is discolored or deteriorated, replace it.)
  1. Start the engine and check if the oil pressure indicator light is turned on. If the light stays on, check the oil pressure indicator light circuit. If the circuit is ok, check the oil pressure in the following manner.
  2.  Remove the left side cowling. Refer to exterior parts removal and installation in section 9d .
  3.  Remove the oil pressure switch lead wire (1) and oil pressure switch (2).

  1. Install the special tools to the mounting hole of the oil pressure switch.

Special tool (a): 0991574521 (adapter hose) (b): 0991517410 (oil pressure gauge adapter) (c): 0991577331 (oil pressure gauge (1000 kpa))

  1. Install the oil pressure switch (2) to the adapter.

  1. Warm up the engine as follows: summer: 10 min. At 2 000 r/min winter: 20 min. At 2 000 r/min
  2.  after warming up, increase the engine speed to 3 000 r/min (observe the tachometer), and read the oil pressure gauge.

    If the oil pressure is lower or higher than the specification, the following causes may be considered.

Oil pressure specification 100 400 kpa (1.0 4.0 Kgf/cm2, 14 57 psi) at 3 000 r/min, oil temp. 60 C (140 f)

High oil pressure

Low oil pressure

  • Engine oil viscosity is too high
  • clogged oil passage
  • combination of the above items
  • Clogged oil filter
  •  oil leakage from the oil passage
  •  damaged o-ring
  •  defective oil pump
  •  combination of the above items
  1. Stop the engine and remove the oil pressure gauge and attachment.
  2.  Reinstall the oil pressure switch. Refer to oil pressure switch removal and installation .
  3. Check the engine oil level. Refer to engine oil and filter replacement in section 0b .
  4.  Install the left side cowling. Refer to exterior parts removal and installation in section 9d (page 9d- 6).
