LUBRICATION
Symptom: LOW OR NO OIL PRESSURE/HIGH OIL CONSUMPTION
1. Check oil level and search for leakage on crankcase and/or sealing parts.
 Crankcase is leaking due to damage. Rebuild engine with new crankcase and
gasket parts. Use recommended oil (refer to technical specifications).
 Crankcase is leaking due to loose screws.
Retighten screws with recommended torque
 Sealing rings, O-rings and/or gaskets are brittle, hard or damaged.
Replace damaged parts.
 Piston rings worn out (blue colored engine exhaust emission).
Replace piston rings (refer to cylinder and head).
 Piston rings are broken (low compression).
Replace piston rings (refer to cylinder and head).
 Valve stem seal damaged and/or sealing lip is hard and/or brittle.
Replace all valve stem seals.
2. Check oil filter for contamination.
 Oil filter clogged. Replace oil and oil filter at the same time.
Use recommended oil (refer to technical specifications).
3. Check oil drain plug on engine bottom.
 Plug is loose and/or gasket ring is missing.
Retighten the plug and/or place gasket ring.
4. Check leak indicator hole if oil leaks (in crankcase MAG side-water pump housing
area).
 Oil leaking from leak indicator hole means a damaged oil seal on water pump
shaft. Replace oil seal (refer to cooling system).
5. Check oil pressure switch function.
 Oil pressure switch damaged. Replace oil pressure switch.
6. Check oil orifice(s) on the oil pump suction side.
 Oil orifice(s) is (are) clogged. Clean from contamination.
Replace oil and oil filter if necessary (refer to maintenance or lubrication system).
7. Check oil pump function.
 Oil pump rotor is out of wear limit. Replace oil pump (refer to lubrication system).
 Oil pump seized due to oil leakage and/or air inclusion.
Replace oil pump (refer to lubrication system).
 Gears driving oil pump are broken or otherwise damaged. Replace gears.
 Incorrect oil being used. Use recommended oil (refer to technical specifications).
8. Check oil pressure regulator valve (spring) function.
 Valve spring damaged (valve always open). Replace spring.
 Valve piston is worn or broken. Replace valve piston (refer to lubrication system).
 Valve piston stays open due to contamination. Clean or repair valve piston.
9. Check plain bearings in crankcase for heavy wear.
 plain bearings out of specification (increased clearance).
Replace plain bearings (refer to bottom end).
