Removal and InstallationEBS01E64
CAUTION:
lBefore removing and installing fuel pump, be sure to remove sprocket. Do not loosen or remove
installation nut in the center of fuel pump. If loosened or removed, replace fuel pump.
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.

d. Tighten bolts in numerical order shown in the figure.
lInstall the following four types of bolts, referring to the figure.
lThe shank length under the bolt neck above is the length of
threaded part (pilot portion not included).
e. After tightening all the bolts, re-tighten in the same order.
3. Install vacuum pump. Refer toEM-42, "
VACUUM PUMP".
4. Install fuel pump. Refer toEM-49, "
FUEL PUMP".
lBefore installing, make sure that spacer and the hole 6 mm
(0.24 in) in diameter on coupling are aligned.
5. Install chain guide and tension guides.
6. Install crankshaft sprocket, aligning it with crankshaft key on the
far side.
7. Install primary timing chain with fuel pump sprocket.
lWhen installing, match the alignment marks on sprockets with
color coded alignment marks (colored links) on primary timing
chain.
lInstall fuel pump sprocket washer with the surface marked “F”
(front mark) facing the front of the engine.
8. Install timing chain onto power steering oil pump sprocket and
through chain guide.
9. Use the positioning stopper pin [SST] to hold the fuel pump
sprocket and install the bolt.
lUsing the TORX wrench [SST], turn the fuel pump shaft little
by little to adjust the position of the fuel pump sprocket. Insert
positioning stopper pin into the hole 6 mm (0.24 in) in diame-
ter on fuel pump sprocket so that the stopper pin goes
through the fuel pump body. While the stopper pin is in place,
install the bolt.16 mm (0.63 in) : Bolt No. 1, 2, 16, 17, 18, 19, 20, 21, 22
