through chain guide.
JEM135G
8. Use the positioning stopper pin (SST) to hold the fuel injection
pump sprocket and install the bolt.
Using a TORX wrench (SST), turn the pump shaft little by little
to adjust the position of the pump flange. Insert positioning
stopper pin (SST) into the hole 6 mm (0.24 in) in diameter on
the fuel injection pump sprocket so that the stopper pin goes
through the pump flange to the pump body. While the stopper
pin is in place, install the bolt.
