NOTE:
• To remove timing chain and associated parts, start with those on the (LH) bank. The procedure for removing
parts on the (RH) bank is omitted because it is the same as that for removal on the (LH) bank.
• To install timing chain and associated parts, start with those on the (RH) bank. The procedure for installing
parts on the (LH) bank is omitted because it is the same as that for installation on the (RH) bank.
REMOVAL
1. Remove the timing chain cover. Refer to
EM-50, "Removal and Installation"
.
2. Without removing them, loosen the camshaft sprocket bolts.
3. Remove the oil pump drive spacer.
• Hold and remove the flat space of the oil pump drive spacer by
pulling it forward.

TIMING CHAIN
a. Squeeze the return-proof clip ends using suitable tool and push
the plunger into the tensioner body.
b. Secure the plunger using stopper pin.
• Stopper pin is made from hard wire approximately 1 mm (0.04
in) in diameter.
c.
Remove the bolts and chain tensioner.
WARNING:
Plunger, spring, and spring seat pop out when (squeezing)
return-proof clip without holding plunger head. It may
cause serious injuries. Always hold plunger head when
removing.
NOTE:
• Stop the plunger in the fully extended position by using the
return-proof clip (1) if the stopper pin is removed.
• Push the plunger (2) into the tensioner body while squeezing
the return-proof clip (1). Secure it using stopper pin (3).
6. Remove the timing chain tension guide and timing chain slack guide.
7. Remove the timing chain and crankshaft sprocket.
8. Loosen the camshaft sprocket bolts using suitable tools as
shown (A) and remove the camshaft sprockets as shown.
CAUTION:
To avoid interference between valves and pistons, do not
turn crankshaft or camshaft when timing chain is discon-
nected.
9. Repeat the same procedure to remove the (RH) timing chain
and associated parts.
INSPECTION AFTER REMOVAL
Check for cracks and any excessive wear at link plates. Replace
chain if necessary.
• In the same way as for the (LH) bank, inspect the timing chain and
associated parts on the (RH) bank.

NOTE:
• The illustration above shows the relationship between the mating mark on each timing chain and that of the
corresponding sprocket, with the components installed.
• To install the timing chain and associated parts, start with those on the (RH) bank. The procedure for install-
ing parts on the (LH) bank is omitted because it is the same as that for installation on the (RH) bank.
1. Make sure the crankshaft key and (RH) bank camshaft dowel
pin and (LH) bank camshaft dowel pin are facing in the direction
shown.
