Injection Nozzles
- Remove nozzles and connect injection nozzle tester. Pump tester lever about 30 times a minute to observe spray pattern. See Fig 1. If spray is faulty, replace injector.
- Pump pressure up slowly to note opening pressure. If not within 1705-1850 psi (120-130 kg/cm2
) for I-Mark models or 1495-1635 psi (105-115 kg/cm2
) on LUV and P'UP models, injector must be replaced.NOTE: When replacing injection nozzles, install parts in this order: ridged washer (with Blue side toward nozzle), gasket, then nozzle holder.
