0115219 EVINRUDE TUBING, Water tube

start by: a) remove fuel injection nozzles Do not disassemble any nozzle until testing has shown that disassembly is needed. Check each nozzle with tool (A) for leakage, opening pressure and the shape and amount of fuel (spray pattern) coming out of zhe nozzle. Do not clean or make an adjustment to any nozzle that has a large (excessive) amount of return leakage. Excessive return leakage can be an indication of nozzle failure that can not be corrected with an adjustment or cleaning and can cause engine damage. See TESTING 9L9263 FUEL INJECTION NOZZLES in TESTING AND ADJUSTING.
Keep the work area and all tools extra clean. Be careful not to cause damage to the parts during disassembly and assembly of the nozzles.
TYPICAL EXAMPLE1. Put the nozzle in position in tool (B). Put tool (B) and the nozzle in a vise. Do not put any part of the nozzle directly in a vise. Loosen locknut (1).
TYPICAL EXAMPLE2. While holding the nozzle in one hand, tilt the nozzle and remove the pressure adjusting screw, locknut and lift adjusting screw, washer, seat, spring, seat, and valve from nozzle body. 3. If the valve does not slide out of the nozzle, install tool (C) and remove the valve as follows: a) Push valve into nozzle with tool (C) until valve is against bottom of nozzle.b) Push down on body of tool (C) to engage collet on valve with tool (C).c) Turn nut counterclockwise and remove valve from nozzle body.4. Put the parts in solvent to loosen carbon and deposits of foreign material. The body is assembled with an epoxy material and must not be in contact with the solvent for more than one to two hours. See SPECIAL INSTRUCTION FORM NO. FM055225 for the correct method of cleaning the nozzle.Assemble Fuel Injection Nozzles (9L9263 Nozzles)
Make sure all of the parts have been thoroughly cleaned before assembling the nozzles. Flush the body to remove any debris or lapping compound.1. Put clean fuel on all of the parts.
TYPICAL EXAMPLE2. Install the lift adjusting screw in pressure adjusting screw (6). Turn the lift adjusting screw into the pressure adjusting screw approximately three turns. Install the locknut on the pressure adjusting screw.
Do not turn the lift adjusting screw into the pressure adjusting screw too far. The valve can be bent during assembly if the lift adjusting screw is turned too far into the pressure adjusting screw.
3. Put washer (5), seat (4), spring (3), and seat (2) in position on the lift adjusting screw.4. Put valve (1) in the nozzle body. Put seat (2) in contact with the valve and push the valve into position in the valve body. Tighten the pressure adjusting screw by hand until the spring will hold all of the parts in place.5. Check the opening pressure of the nozzle as controlled by pressure adjusting screw (6) with tool (B). See TESTING 9L9263 FUEL INJECTION NOZZLES, OPENING PRESSURE TEST in TESTING AND ADJUSTING. 6. Check the valve lift adjustment as controlled by lift adjusting screw (8) with tool (B). See TESTING 9L9263 FUEL INJECTION NOZZLES, VALVE LIFT ADJUSTMENT in TESTING AND ADJUSTING.
TYPICAL EXAMPLE7. Put the nozzle in position in tool (A). Put the nozzle and tool (A) in a vise. Hold the pressure adjusting screw with a wrench and tighten locknut (7) to a torque of 70 to 75 lb.in. (80.7 to 86.5 cm.kg) with tool (C) and a torque wrench.end by: a) install fuel injection nozzles
