LU-4 ENGINE OIL ENGINE OIL PFP:KLA92 Inspection EBS00OIJ OIL LEVEL AND CONTAMINATION ● Before starting the engine, put vehicle horizontally and check the oil level. If the engine is already started, stop it and allow 10 minutes before checking. ● Check that the oil level is within the range shown in the figure. ● If oil level is outside the range, adjust level. ● Check the oil for white turbidity or remarkable contamination. ● If the oil becomes turbid and white, it is highly probable that it is contaminated with coolant. Find the cause and repair. ● When oil level gauge is inserted in guide, apply engine oil to rub- ber seal of grip. OIL LEAK Check the following parts for engine oil leaks. ● Oil pan ● Oil pan drain plug ● Oil pressure switch ● Oil filter ● Front cover ● Cylinder head front cover ● Mating surfaces of cylinder block and cylinder head ● Mating surfaces of cylinder head and rocker cover OIL PRESSURE CHECK WARNING: ● Be careful not to burn yourself, as the engine oil is hot. ● Oil pressure check should be done in “Parking” or “Neutral” position. 1. Check the engine oil level. 2. Remove oil filter. Refer to LU-6, " OIL FILTER " . 3. Remove oil pressure switch and connect an oil pressure gauge. 4. Install oil filter. Refer to LU-6, " OIL FILTER " . 5. After warming up the engine, check that oil pressure corresponding to the engine speed is produced. NOTE: Low oil temperature creates high pressure.

ENGINE OIL LU-5 C D E F G H I J K L M A LU Engine oil pressure [When oil temperature is 80 °C (176 °F)] 6. After checking the oil pressure, install oil pressure switch as follows: a. Remove old sealant on the switch and engine. b. Apply thread sealant and tighten. Use Genuine Liquid Gasket or equivalent. CAUTION: Be careful not to get burned when engine or engine oil is heated. Changing Engine Oil EBS00OIK WARNING: ● Be careful not to burn yourself, as the engine oil is hot. ● Prolonged and repeated contact with used engine oil may cause skin cancer: try to avoid direct skin contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible. 1. Warm up engine, and check for oil leakage from engine components. 2. Stop engine and wait for 10 minutes. 3. Remove oil filler cap, and remove drain plug. 4. Drain engine oil. 5. Install drain plug. Refill with new engine oil. ● Install drain plug washer in the direction shown in figure. ● Oil specification and viscosity: Refer to MA-12, " RECOMMENDED FLUIDS AND LUBRI- CANTS " . Oil capacity (Approximate): Unit: (Imp qt) CAUTION: ● Be sure to clean drain plug and install with new washer. ● The refill capacity depends on the oil temperature and drain time. Use these specifications for ref- erence only. Always use the dipstick to determine when the proper amount of oil is in the engine. 6. Warm up engine and check area around drain plug and oil filter for oil leakage. 7. Stop engine and wait for 10 minutes. 8. Check oil level. Refer to LU-4, " Inspection " . Engine speed (rpm) Idle speed 2,000 6,000 Engine oil pressure kPa (bar, kg/cm 2 , psi) Approx. 44.1 (0.441, 0.45, 6.4) or more Approx. 265 (2.65, 2.7, 38) or more Approx. 373 (3.73, 3.8, 54) or more : 18.7 - 20.5 N·m (1.9 - 2.0 kg-m, 14 - 15 ft-lb) PBIC1468E Drain and refill With oil filter change 3.0 (2-5/8) Without oil filter change 2.8 (2-1/2) Dry engine (engine overhaul) 3.5 (3-1/8) Oil pan drain plug: : 29.4 - 39.2 N·m (3.0 - 3.9 kg-m, 22 - 28 ft-lb)
