Removal and Installation

INFOID:0000000009886431

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.

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.
