Oil Spray Jet: Testing and Inspection
Oil Jet Inspection1. Remove the oil jet, and inspect it as follows.
^ Make sure that a 1.2 mm (0.05 in.) diameter drill will go through the nozzle hole (A) (1.31 mm (0.052 in.) diameter).
^ Insert the other end of a 3.7 mm (0.15 in.) drill into the oil intake (3.8 mm (0.15 in.) diameter). Make sure the check ball (B) moves smoothly and has a stroke of about 2.0 mm (0.08 in.).
^ Check the oil jet operation with an air nozzle. It should take at least 380 kPa (3.9 kgf/cm2, 55 psi) to unseat the check ball.
2. Carefully install the oil jet. The mounting torque is critical.
Specified Torque: 16 N-m (1.6 kgf-m, 12 lbf-ft)
