19. Using the sprocket holder (SST), hold the fuel supply pump
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:
Do not remove the sprocket holder until the fuel supply
pump is installed.
lAfter the sprocket holder is installed, pull out the positioning
stopper pin (SST) from the fuel supply pump sprocket.
20. Using the extension bar [SST: whole length 43 mm (1.69 in)] and
the TORX socket (Q6-E12: commercially available), remove the
mounting bolts, them remove the fuel supply pump toward the
rear of the engine
CAUTION:
Do not disassemble or adjust the fuel supply pump.

INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks and excessive wear at roller links. Replace
chain if necessary.
INSTALLATION
1. Before the fuel supply pump is installed, check that the notch of
its flange and the 6 mm (0.24 in) dia. hole on the body are
aligned.
2. Insert the fuel supply pump to the mounting position from the

mounting bolts of the fuel supply pump.
4. Remove the sprocket holder (SST).
5. Using the TORX wrench (SST), turn the pump shaft gradually to
adjust the position of the flange. Then, insert the positioning
stopper pin (SST) to the 6 mm (0.24 in) dia. hole of the fuel sup-
ply pump sprocket through the pump flange and the pump body.
6. Remove the TORX wrench (SST)
7. Using the hexagon wrench [face to face: 6 mm (0.24 in), long-
type}](SST), tighten the sprocket mounting bolt.
lWhen the washer of the fuel supply pump sprocket is
removed, install it with the marking “F” (front) facing the front
of the engine.
8. Pull out the positioning stopper pin (SST).

SST], install timing chain slack guide.
12. Install chain tensioner.
a. Push the plunger of the chain tensioner. While holding it with a
push pin, install the chain tensioner.
b. Using a hexagon-head wrench [face to face: 5 mm (0.20 in),
SST], tighten bolts.
c. Pull out the push pin, etc. holding the plunger.
lCheck again that the alignment marks on the sprockets
and the colored alignment marks on the timing chain are
aligned.
