3. TEMPORARILY INSTALL IDLER PULLEY AND TENSION SPRING

Push the idler pulley toward the alternator side as far as it will go and temporarily tighten it.

4. TEMPORARILY INSTALL TIMING BELT ON CRANKSHAFT TIMING PULLEY

(a) Check the rotation direction mark placed on the timing belt during disassembly.

(b) Install the timing belt on the crankshaft timing pulley.

5. INSTALL NO. 1 TIMING BELT COVER

6. INSTALL BRACKET OF COOLER COMPRESSOR

7. INSTALL CRANKSHAFT PULLEY

(a) Install the crankshaft pulley and pulley bolt.

(b) Using SST to hold the crankshaft pulley, torque the pulley bolt.

SST 09213-70010 and 09330 00021

8. REMOVE OIL FILLER CAP AND CYLINDER HEAD COVER OF EXHAUST SIDE

9. INSTALL CAMSHAFT TIMING PULLEY AND TIMING BELT

(a) Make sure that the match hole on the No. 2 journal of the camshaft housing is aligned with that of the camshaft.

If not aligned, temporarily install the camshaft timing pulley and insert the match pin into the pin hole.

Then, align the match holes by turning the camshaft timing pulley.

<f) There are three pin holes on the camshaft and timing pulleys.

Select one overlapped hole and insert the pin into it. NOTE:

• If there is no overlapping hole, find one that is nearly overlapped and rotate the crankshaft slightly to overlap it and insert the pin.

• The crankshaft pulley angle can be adjusted approximately 3° by changing the pin hole to the next one.

(g) Using SST to hold the pulley, install the bolt. SST 09278-54012

CAUTION: Do not make use of the timing belt tension when tightening the bolt.

(h) Loosen the idler pulley set bolt.

(i) Turn the crankshaft clockwise two times, (j) Retighten the idler pulley set bolt.

10. CHECK TIMING MARKS

(a) Rotate the crankshaft two times clockwise.

(b) Check the timing marks. (Refer to the section of INSPECTION AND ADJUSTMENT OF VALVE TIMING —See page EM-7)
