Removing injection nozzleRefitting Accessories
General Points
Refit accessories by following the removal procedures in reverse. After refitting accessories, perform the following:(1) Pour the specified amount of engine oil into the engine.(2) Pour coolant into the coolant system.(3) To facilitate starting, pour engine oil into the governor's hydraulic oil filter via the hole of the air bleeding plug.(4) Make sure no oil or coolant is leaking from joints and connections.(5) Air-bleed the fuel system.(6) After refitting the injection pump (see the instructions below), be sure to inspect and adjust the injection timing.Installing Injection Pump
Installation should be performed basically by following the removal procedure in reverse. The following operations must also be performed.(1) Bleeding Air from Fuel System
Bleeding air from fuel system(a) Feed fuel to the engine by turning the key to the ON position. Then, loosen the air vent screw (1), allow air in the filter to be expelled, and retighten the screw.(b) Loosen air vent screws (2) and (3) on the injection pump in that sequence to bleed air from the
