2. Remove the timing belt cover bolt as shown.
3. Remove the cylinder head cover. (See B2–15
CYLINDER HEAD GASKET REPLACEMENT.)
4. Turn the crankshaft clockwise and set the No.1
cylinder to compression TDC.
5. Remove the fuel injector. (See F2–55 FUEL
INJECTOR REMOVAL/INSTALLATION.)
6. Adjust the valve clearance A with the No.1
cylinder at TDC of compression, and those of B
with the No.4 cylinder at TDC of compression.
(1) Hold the rocker bridge using the SST (49
G012 006).
(2) Loosen the locknut (d) using the SST (49
G012 004), and then turn the adjusting screw
(c) using the SST (49 G012 005) until it is
separated from the valve stem completely.

Caution
•To prevent the bolts (M8 x 1.25) from damaging the fuel injection pump and pulley, do not fully
tighten the fixing bolts. If it contacts the pulley surface, it will damage the pulley.
4. Verify that all timing marks are correctly aligned.
•If not, align all timing marks according to the
procedure below.
5. Fix the camshaft pulley to the cylinder head using
bolt (M8 x1.25).
6. Fix the injection pump pulley to the bracket using
two bolts (M8 x1.25).
Caution
•Turn the crankshaft in the direction
which will prevent the TDC and BDC from
being passed. Otherwise it can cause the
valve and piston to come into contact.
(1) Turn the crankshaft and set it at an angle of 45° or more away from the TDC and BDC.
(2) Align the timing marks of the camshaft pulley.
(3) Align the timing marks of the injection pump pulley.
(4) Turn the crankshaft and align the timing marks of the timing belt pulley.
7. Install the timing belt on the pulleys in the order
shown below.
(1) Timing belt pulley
(2) Idler
(3) Supply pump pulley
(4) Camshaft pulley
(5) Water pump pulley
(6) Tensioner
8. Remove the supply pump pulley fixing bolts and
camshaft pulley fixing bolt (M8 x 1.25).
9. Hand tighten the timing belt auto tensioner bolts
in the order A to B as indicated in the figure.
10. Tighten the timing belt auto tensioner bolts in the
order A to B as indicated in the figure.
Tightening torque
19—25 N·m {1.9—2.6 kgf·m, 14—18 ft·lbf}
11. Remove the pin from the timing belt auto
tensioner to apply tension to the belt.
12. Turn the crankshaft clockwise twice, and align the
timing marks.
13. Verify that all timing marks are correctly aligned.
•If not as specified, repeat from Timing Belt,
