NOTE:
To remove timing chain and related parts, start with those on left bank. The procedure for removing parts
on right bank is omitted because it is
the same as that for left bank.
a. Press tab in the direction of arrow (or turn lever in the direction of arrow) to unlock the locking with the groove that stops ten-
sioner plunger from returning.
 Lightly press tensioner plunger to release the tension of springfor this operation.
b. Push in tensioner plunger to align the hole on lever and that on pump main body.
 Pushing in tensioner too far does not allow the holes to align.Therefore, push in plunger to the degree at which the start of
stopper groove and tab engages.
c. Insert stopper pin [hard wire with approx. 0.5 mm (0.020 in) diameter or similar tool] to fix plunger. With plunger fixed,
remove chain tensioner.
17. Remove chain tension guide and timing chain slack guide.
18. Remove timing chain and crankshaft sprocket. CAUTION:
After removing timing chain, do not turn cranksh aft and camshaft separately, or valves will strike
the piston head.
19. With hexagonal part of camshaft locked with wrench, loosen mounting bolts securing camshaft sprocket to remove camshaft
sprocket.
CAUTION:
Do not loosen mounting bolts with securing anything other
than the camshaft hexagonal porti on or with tensioning the
timing chain.
20. Perform same procedure as for left bank, remove timing chain and related parts on right side.
21. Use scraper to remove all traces of old liquid gasket from front cover and opposite mating surfaces.  Remove oil liquid gasket from bolt hole and thread.
22. Use scraper to remove all trace of liquid gasket from chain tensioner cover and intake valve timing control covers.

1. Make sure that crankshaft key and dowel pin of each camshaft
are located as shown in the figure. (No. 1 cylinder at compres-
sion TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
2. Install camshaft sprockets.  Install onto correct side by checking with identification mark onsurface.
 Install camshaft sprocket (EXH) by selectively using the
groove of dowel pin according to the bank. (Common part
used for both banks.)
 Lock the hexagonal part of camshaft in the same procedure as for removal, and tighten mounting bolts.
3. Install crankshaft sprockets for both banks.  Install each crankshaft sprocket so that its flange side (thelarger diameter side without teeth) faces in the direction shown
in the figure.
NOTE:
The same parts are used but facing directions are different. Camshaft dowel pin
: At cylinder head upper face side in each bank
Crankshaft key : At cylinder head side of left bank

3. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
CAUTION:
 Do not loosen mounting bol ts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
 After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike the piston head.
4. Remove intake and exhaust camshaft brackets.  Mark camshafts, camshaft brackets and bolts so placed in the same position and direction for installa-
tion.
 Equally loosen camshaft brackets and bolts in several steps in reverse order as shown in the figure.
 Lightly tapping with plastic hammer, remove camshaft bracket (No. 1) and camshaft bracket (No. 6).
NOTE:
The bottom surface of each bracket will be stuck to cylinder
head because of liquid gasket.
5. Remove camshaft.
6. Remove valve lifter if necessary.  Identify installation positions, and store them without mixing them up.

Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journalof camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a differe nt diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
