Oil Jet Inspection

Remove the oil jet (see OIL JET REPLACEMENT ), 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 1 9 mm (0 07 in) drill into the oil intake (2 0 mm (0 08 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 325 kPa (3 3 kgf/cm² , 47 psi) to unseat the check ball
NOTE: Replace the oil jet assembly, if the nozzle is damaged or bent
