FUEL SYSTEM – STRUCTURE AND FUNCTION
The block assembly in place can be angularly repositioned, relative to the pump housing, by turning the flange sleeve. Turning the block affects the injection timing. Thus, the relationship between the plunger and the inlet port is determined by the angular and vertical positions of the block assembly in the housing.
The pressure-feed lubrication mentioned previously refers to the tappets. Pressurized lubricating oil is led into the pump housing from the engine lubricating system. An oil orifice opens out into the bore in which the tappet reciprocates in sliding contact. The oil is forced through the orifice into this sliding clearance around the tappet. The camshaft and the moving parts in the governor are lubricated with this oil. A return line is provided to return the oil back to the engine lubricating system.

10 Structure, function and maintenance standard SEN00309-04
(*) The CRI system controls the fuel injection rate and fuel injection timing more properly than the mechanical governor or timer of the conventional fuel injection pump.
(*) For the control of the system, calculations necessary to the ECU are performed from the signals sent from the sensors installed to the engine and machine.
(*) The energizing timing and energizing period of the injector are so controlled that the optimum quantity of fuel will be injected in the optimum timing.
1. Fuel injection rate control function
(*) The fuel injection rate control function is employed instead of the function of the conventional governor. It controls the fuel injection according to the signals of engine speed and accelerator angle so that the fuel injection rate will be most proper.
2. Fuel injection timing control function
(*) The fuel injection timing control function is employed instead of the function of the conventional timer. It controls the fuel injection timing most properly from the engine speed and fuel injection rate.
3. Fuel injection pressure control function (Common rail fuel pressure control function)
(*) The fuel injection control function (common rail fuel pressure control function) controls the fuel discharge rate of the fuel supply pump by measuring the fuel pressure by the common rail fuel pressure sensor and feeding it back to ECU.
(*) This function performs pressure feedback control so that the fuel injection pressure will be the same as the optimum value (command value) set according to the engine speed and fuel injection rate…

REPAIR AND REPLACEMENT OF PARTS CYLINDER BLOCK
GRINDING CRANKSHAFT
★ When grinding the crankshaft to correct wear, light seizure or damage, grind to an undersize.
★ If there is curvature of the crankshaft, it is preferable to replace the crankshaft and not to grind it to an undersize. (There are problems with balancing.)
★ Do not try to correct a bent crankshaft with a press. When the engine is run, the crankshaft will gradually return to its bent shape.
★ The journal portion has been given induction hardening, so do not try to repair it by bead welding or plating.
★ Unevenly worn crankshafts will bend or be unbalanced even if repaired, so always replace unevenly worn crankshafts.
★ Measure the part for grinding to decide the undersize dimension.
★ Judge from the measured dimension, and if the undersize dimension will exceed the repair limit, replace the crankshaft.
★ When repairing the plating of the damaged surface, repair only the following places.
1) Rear seal journal portion
2) Crankshaft gear mount
★ When correcting damage to the crankshaft, pay particular attention when finishing the R portion of the fillet and shoulder r (see the diagram on the right) and the R at the inlet port of the oil hole.
