●No position indicator is provided on the crankshaft pul-
ley.
●When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
supply pump sprocket may not be easy to see.

19. Using a hexagon-head wrench [face to face 6 mm (0.24 in) SST]
remove bolts to fuel supply pump sprocket.
20. Using the sprocket holder (SST), hold the fuel supply pump
sprocket to prevent falling.
●As for the sprocket holder, install fuel supply pump mounting
bolt through hole of KV11106060 as shown in figure.
●When 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.
●After 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.
●The length of the sprocket holder mounting bolts should be
approximately 15 mm (0.59 in) (M6 thread length).
●Make 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.
●After the sprocket holder is installed, pull out the positioning
stopper pin (SST) from the fuel supply pump sprocket.

INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks and excessive wear at roller links. Replace
chain if necessary.
INSTALLATION
1. Install new O-rings to the fuel supply pump housing.
2. Install fuel supply pump housing to the fuel supply pump.
●Using a hexagon -head wrench [face to face 5 mm (0.20 in)
SST], tighten the fuel supply pump housing mounting bolt.
3. Install coupling to the fuel supply pump.
●Using the TORX wrench (SST), tighten the sprocket nut to fix
the coupling.
4. Install adjusting shim.
●For shim adjustment, measure dimension L (Distance
between front surface of the coupling and the fuel supply
pump flange) at 2 opposing points near the coupling bolt cen-
ter. Use the average of these two measurements to select the
shim grade that marked on adjusting shim.
●The shim adjustment is required only when the fuel supply
pump is replaced.
