Engine Lubrication: Testing and Inspection

Lubrication system (FA20)

Function inspection

1. Engine oil level check
(1) Park the vehicle on a level surface.
(2) Remove the oil level gauge and wipe away the oil.
(3) Reinsert the oil level gauge all the way. Be sure that the oil level gauge is correctly inserted and properly orientated.
(4) Pull out the oil level gauge again, and check both sides of the oil level gauge. Use a lower side to determine the engine oil level. If the engine oil level is below the L mark, check the engine for oil leakage and refill the oil to bring the level up to the F mark.
(5) Start the engine to circulate the oil in the engine.





(6) Five minutes after stopping the engine, check that the engine oil level is between the L and F marks of oil level gauge. If the oil level is low, check for oil leakage and refill the oil up to the F mark.

NOTE:
^ To prevent overfilling of the engine oil, do not refill the oil above the F mark when the engine is cold.
^ As the oil level gauge is used for daily maintenance, the F and L marks are set assuming that the engine is cold.

2. Engine oil quality check
(1) Check the oil for degradation, mixture of moisture, discoloration and dilution. Replace the oil when its quality has deteriorated clearly.
3. Oil pressure check

CAUTION:
Wash the equipment, hoses, etc. with white gasoline before and after the measurement.

(1) Remove the engine oil pressure switch ASSY.





(2) Install the oil pressure gauge using the adapter.
(3) Install the air cleaner case SUB-ASSY.
(4) Warm up the engine.
(5) Measure the oil pressure.
Standard value:





(6) Remove the air cleaner case SUB-ASSY.
(7) Remove the oil pressure gauge.
(8) Install the engine oil pressure switch ASSY
