8Fuel systemHIGH PREASSURE HOLEREFERENCE NUMBERLOCATING PEGOFFSET HOLESOLD TYPE INJECTOR PUMP INTERMEDIATE INJECTOR PUMP CURRENT PUMP INJECTOR176Lombardini injection system is being steadily implemented, seeking the best performance of its engines.For this reason the pump injector body has been modified three times in the course of its evolution.Three different pump injectors are shown in the top figure.Old type injector pump:Intermediate injector pump:Current pump injector:it is characterised by its high pressure holeis characterised by not having the high pressure hole (the hole can be there but it is only usedto control the injector and injection advance) and by the locating peg between inlet and outletholes.it is characterised by its offset inlet and outlet holes. These are also oversized, due to theabsence of the high pressure hole.REFERENCEN°CODE N°ENGINE TYPEINJECTIONADVANCE VALUESPECIAL TOOLS231-2272-0235-2272272-1272-272+235-4235-4235-3235-46590.2626590.2836590.2356590.2726590.2856590.2866590.3076590.2906590.2876590.290502 - 602 - 903 - 1204502 MINI CAR1204/T502 - 602 - 903 - 1204502 - 602 - 903 - 1204502 MINI CAR1204/T702 - 1003 - 140411° - 13°11° - 13°4° - 6°8° - 10°8° - 10° < 2999 g/min12° - 14° > 3000 g/min11° - 13°6° - 8°8° ÷ 10° < 2999 g/min12° ÷ 14° 3000÷3600 g/min13° ÷ 14° > 3600 g/minADVANCE .......................... 1460.028 + 1460.024INJECTOR SETTING ........ 1460.028T.D.C. ................................. 1460.048ADVANCE .......................... 1460.028 + 1460.024INJECTOR SETTING ........ 1460.028T.D.C. ................................. 1460.048ADVANCE .......................... 1460.028 + 1460.024INJECTOR SETTING ........ 1460.028T.D.C. ................................. 1460.048ADVANCE .......................... 1460.056INJECTOR SETTING ........ 1460.028T.D.C. ................................. 1460.048ADVANCE / INJECTOR SETTING ........ 1460.074T.D.C. ..................................................... 1460.048ADVANCE / INJECTOR SETTING ........ 1460.074T.D.C. ..................................................... 1460.048ADVANCE / INJECTOR SETTING ........ 1460.074T.D.C. ..................................................... 1460.048ADVANCE / INJECTOR SETTING ........ 1460.074T.D.C. ..................................................... 1460.048- 78 - FOCS Workshop Manual_cod. 1.5302.351_7° ed_ rev. 06
Fuel system8Injector, setting (old type)177Connect the injector to a hand pump after removing cap screw 20fig. 169.By means of the tool - se.no. 7107-1460-028 - check that thesetting pressure is 130÷145 bar.Adjust, if necessary, by changing the spacer located under thespring.There are eleven different spare part spacers from 1 to 2 mm.When you replace the spring, the setting should be made at apressure higher than 10 bar to compensate for adjustments inoperation.Check the needle seal by slowly actuating the hand pump for 10seconds, until you reach abt. 130 bar.If the nozzle drips, replace it.Setting of injector according to current pump/injector unitRemove the non-return valve leaving its metal gasket and fit a capscrew in its place, that is part of tooling 7107-1460-074.Mount then head 1 and coupling 2.Then connect a hand pump as shown in the picture.The pressure setting must be 140÷155 mm bar.178Injector, nozzle projectionTo avoid excessive compression of the spark arrester A, fig. 181,check projection B of the nozzle fig. 179.B = 6.80÷7.05 mm.If this measure is larger put spacer 2 between ring nut 1 and coppergasket 3.0.25 mm thick spacers are available.179180Injector, spark arresterEvery time you remove the pump/injector you must replace thespark arrester, the copper gasket, the oil O-ring, as well as the 2 fuelO-rings.Insert the spark arrester in the injector housing with surface Apointing upwards. Tighten simultaneously both nuts that fasten it to the head at 20Nm.For engines with the injectors fixed with self-locking nuts, tightenthe nuts at 23 Nm.181 See page 24 for periodic maintenance details.FOCS Workshop Manual_cod. 1.5302.351_7° ed_ rev. 06- 79 -
