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.

21. Remove the fuel supply pump mounting bolts.
NOTE:
The seal washer of the mounting bolts cannot be reused.
CAUTION:
For removal, be careful not to drop the seal washer into the
engine.
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
rear side of the engine.

3. Using the extension bar (SST) and the TORX socket, tighten 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).

lWhen installing, match the alignment marks on sprockets with
color coded alignment marks (colored links) on the chain.
10. Install timing chain tension guide.
lThe upper bolt has a longer shank than the lower bolt.

13. Install front chain case.
a. Install tension guide on the back surface of front chain case.
lHold front chain case vertically when installing. Tension guide
may come off if front chain case is tilted.

"Precautions for Liquid Gasket".) on both ends of arched area
(locations where rear chain case is adjoined) as shown in the
figure.
c. Install front chain case.
lWhen installing, align dowel pin on oil pump case with the pin
hole.
lInstall No. 6, 10 and 11 bolts with the rubber washer to the
front chain case.
d. Tighten fixing bolts in the numerical order shown in the figure.
e. After tightening all the bolts, re-tighten in the same order.
14. Install the fuel supply pump rear bracket.
lTighten fixing bolts in the numerical order shown in the figure.
15. Install the harness connector from fuel supply pump.
16. Install fuel hoses.
17. Hereafter, install in the reverse order of removal.

CAMSHAFT
Valve Clearance
EBS00BOJ
INSPECTION
lWhen the camshaft or parts in connection with valves are
removed or replaced, and a malfunction has occurred (poor
starting, idling, or other malfunction) due to the mis adjustment
of the valve clearance, inspect as follows.
lInspect and adjust when the engine is cool (at normal tempera-
ture).
lBe careful of the intake and exhaust valve arrangement. The
valve arrangement is different from that in a normal engine.
NOTE:
The camshafts have, alternately, either an intake valve or an
exhaust valve.(Refer to illustration)
1. Drain engine coolant. Refer toCO-30, "
Changing Engine Coolant".
2. Remove charge air cooler. Refer toEM-114, "
Removal and Installation".
3. Remove air duct and air inlet pipe. Refer toEM-112, "
Removal and Installation".
4. Remove rocker cover. Refer toEM-147, "
Removal and Installation".
5. Remove vacuum pump. Refer toEM-131, "
Removal and Installation".
6. Remove injection tube and fuel injector. Refer toEM-135, "
Removal and Installation".
7. Remove secondary timing chain. Refer toEM-158, "
Removal and Installation"
Check valve clearance while engine is cold and not running.
8. Set the No. 1 piston to TDC on its compression stroke.
lTurn crankshaft pulley clockwise so that the knock pin on
camshaft LH faces straight above. (No position indicator, etc.
is provided on the crankshaft pulley.)
9. Put an alignment mark with paint, etc. on the crankshaft pulley
and on the oil pump as an angle indicator.
10. While referring to the figure, measure the valve clearance
marked in the table below.
lThe injection order is 1-3-4-2.

CAUTION:
lAfter removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.
lWhen installing camshafts, chain tensioners, oil seals or other sliding parts, lubricate contacting
surfaces with new engine oil.
lApply new engine oil to parts marked in illustration before installation.
REMOVAL
lFor preparative work for removing/installing secondary timing chain to remove/install electronic fuel supply
pump. Refer toEM-138, "
FUEL SUPPLY PUMP".
lTo prepare for removing/installing secondary timing chain to remove/install camshaft. Refer toEM-149,
"Removal and Installation".
1. Remove coolant reservior tank.
2. Remove RH engine mount insulator and bracket. Rfer toEM-184, "
Removal and Installation".
3. Pull power steering reservoir tank out of brackets to move power steering piping.

4. Remove front chain case.
lLoosen fixing bolts in the reverse order of that shown in the
figure and remove them.
lRemove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
lWhile front chain case is removed, cover openings to
prevent entry of foreign material into engine.
lDo not remove two mass dampers on the back of cover.
5. Set the No. 1 piston to TDC on its compression stroke.
lTurn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
showninthefigure.
lNo position indicator is provided on the crankshaft pul-
ley.
lWhen 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.
6. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.
b. Using a hexagon-head wrench [face to face: 5 mm, (0.20 in)
SST], remove bolts to remove chain tensioner.
