Oil Spray Jet: Testing and Inspection
1. Remove the oil jet and inspect it as follows.
-
Make sure that a 1.1 mm (0.04 inch) diameter drill will go through the nozzle hole (1.2 mm (0.05 inch) diameter).
-
Insert the other end of the same 1.1 mm (0.04 inch) drill into the oil intake (1.2 mm (0.05 inch) diameter).
-
Make sure the check ball moves smoothly and has a stroke of approximately 4.0 mm (0.16 inch).
-
Check the oil jet operation with an air nozzle. It should take at least 200 kPa (28 psi) to unseat the check ball.
NOTE: Replace the oil jet assembly if the nozzle is damaged or bent.
2. Mounting torque of 16 Nm (12 ft. lbs.) is critical. Be very precise when installing.
