- Make sure that a 1.1 mm (0.04 in.) diameter drill will go through the oil intake (1.2 mm (0.05 in.) diameter). Make sure the check ball (A) moves smoothly and has a stroke of about 4.0 mm (0.16 in.).
- Check the oil jet operation with an air nozzle. It should take at least 310 kPa (3.2 kgf/cm2, 46 psi) to unseat the check ball.
