3.3.23. Fuel injection pump z Turn the crank shaft so as to let the cylinder No.6 for P158LE, PU158TI, P222LE, PU222TI engines and the cylinder No.7 for P180LE, PU180TI come to the overlap TDC (Top Dead Center). z Rotate the crankshaft to reverse about 30 ° (in order to remove a backlash), and then rotate it to engine rotating direction to set the fuel injection timing angle. z Coat the O-ring with grease and insert it at the lower part of fuel injection pump. (Be careful O-ring not to be removed). z Prior to install the fuel pump drive gear, fit the rubber gasket first.
z Tighten temporarily the fuel injection pump drive gear with aligning the pointer on drive gear with injection pump pointer. z Fit the injection pump in the appropriate position using a special tool. (Special tool no. : EF120-189). EB2O3008 z After fixing the jig hole on the limit cap of the injection pump rotate the jig counterclockwise and align the jig pin to the machined corner of the cylinder block, then assemble the injection pump. z After completing the preparation for injection pump assembling, install the injection pump and tighten the bolts in EFM2071I the zigzag method.
z After assembling the injection pump, find out whether the injection pump pointer and drive gear’s pointer is aligned, and if aligned, tighten the fixing bolts that were temporarily tightened. However, if not aligned, loosen the fixing bolts and turn the fuel pump so as to align the pointers then tighten the fixing bolts. Engine Reassembly - 92 - EFM2071I
