Check each nozzle with tool (A) for leakage, the pressureat which the nozzle opens, and the shape and amount of fuel (spraypattern) that comes out of the nozzle. Do not clean or make anadjustment to any nozzle that has a large (excessive) amount ofreturn leakage. Excessive return leakage can be an indication ofnozzle failures that can not be corrected with an adjustment orcleaning and can cause engine damage. See TESTING FUELINJECTION NOZZLES in TESTING AND ADJUSTING.CAUTION: Keep the work area and all tools extraclean. Be careful not to cause damage to the parts whilethe nozzles are disassembled and assembled.1.Remove cap (1) from the fuel injection nozzle.2.Put the nozzle in tool (B).
