3.1.1 Checking before installing fuel injection pump
(1) When installing the right bank fuel injection pump,
rotate the crankshaft so that No. 1 piston is at the top
dead center of compression stroke, and when installing
the left bank fuel injection pump, rotate the crankshaft
so that No. 7 piston is at the top dead center of com-
pression stroke.
(2) Remove the tentatively installed drive coupling and
laminated plates set on the drive coupling from the fuel
injection pump. Install the coupling and the set to the
accessory drive shaft with the woodruff key. Push the
drive coupling to the accessory drive as close as possi-
ble, and leave the tightening bolts loose.
(3) Align the line mark on the fuel injection pump coupling
(or timer) with the pointer.
(the injection start timings of cylinder No. 1 and No. 7)
Pointer and Line Mark - Align
