Oil Jet: Inspection
- Ensure a 1/32" (1.1 mm) drill bit will go through 0.05" (1.2 mm) hole in oil jet nozzle. Clean as necessary. If oil nozzle is damaged or bent, replace oil jet assembly.
- Insert smooth end of 1/32" (1.1 mm) drill bit into 0.05" (1.2 mm) hole in oil jet intake. Ensure check ball at bottom of hole moves smoothly and has a stroke of about 0.16" (4.1 mm).
- Using an air nozzle with regulated air supply, check oil jet operation. Apply low air pressure to oil jet intake and slowly increase until check ball is unseated. Check ball should not unseat until air pressure is at least 28 psi (2.0 kg/cm2 ). Replace oil jet assembly if operation is not as specified.
