(2)   Consult your nearest Caterpillar Dealer. NOTE: Ensure that the new fuel injection nozzles have the same   identification   code   as   the   nozzles   which were originally installed in the cylinder head.

Refer to the Testing And Adjusting, "Fuel Lift Pump Pressure Test" in order to test the operation of the fuel lift pump. NOTE:    When the fuel lift pump is installed on the engine, ensure that the camshaft is on minimum lobe lift and that the bolts are evenly tightened.  Failure to follow   this   procedure   can   cause   the   loss   of maximum engine power and damage to the fuel It pump. 5-11
