CAUTION:
Never start engine with vacuum circuit being open. If
engine is started and vehicle is running while vacuum
pump is open (with vacuum hose disconnected), blow-by
flow rate will increase and engine may be damaged.
6. Install in reverse order of removal after this step.
●When vacuum hose is connected, insert it securely by at least
15 mm (0.59 in).

6. Connect injection tubes individually to each cylinder in order of
3-4-1-2.
7. Connect spill hose.
8. Install remaining parts in reverse order of removal.
INSPECTION AFTER INSTALLATION
CONSULT-ll service support has a force rail pressure increase function and can increase rail pressure to any
given pressure. Check for fuel leaks visually by increasing internal pressure using this function.

CAUTION:
●Before removing and installing fuel supply pump, be sure to remove sprocket. Do not loosen or
remove installation nut in the center of fuel supply pump. If loosened or removed, replace fuel
supply pump.
●After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.
●When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting
surfaces with new engine oil.
●Apply new engine oil to parts marked in illustration before installation.
REMOVAL
1. Remove engine coolant reservoir tank.

cover.
13. Set the No. 1 piston to TDC on its compression stroke.
●Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
●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.

sprocket to prevent falling.
●As for the sprocket holder, install fuel supply pump mounting
bolt through hole of KV11106060 as shown in figure.

●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.
