sprocket to prevent falling.
lAs for the sprocket holder, install fuel supply pump mounting
bolt through hole of KV11106060 as shown in figure.
lWhen the sprocket holder is installed, if the positioning stop-
per pin interferes, pull out the stopper pin approximately 10
mm (0.39 in), then install it.
lAfter the sprocket holder is installed temporarily, insert the
extension bar (SST) and TORX socket in the three holes A.
After positioning the holes, tighten the holder mounting bolts.
lThe length of the sprocket holder mounting bolts should be
approximately 15 mm (0.59 in) (M6 thread length).
lMake sure that the a- and b-faces of the sprocket holder con-
tact the bottom side of the sprocket (small diameter side).
CAUTION:
