(2) Install drive coupling temporary attached to the fuel
injection pump to the accessory driving shaft with the

pump. The shaft tightening bolt should be loosened at
this time.
(3) Align the "0" line mark on the fuel injection pump fly-
wheel with the pointer. (Injection start timing of cylin-
der No. 1)
