6. CHECK CAMSHAFT TIMING PULLEY MARKS

(a) Turn the crankshaft clockwise and set the No. 1 cylinder to TDC/compression.

<b) Check that the matchmarks of the camshaft timing pulleys are aligned with those of the No. 2 timing belt cover.

• If there is more than timing pulley one tooth between the matchmarks, realign the matchmarks in accordance with step 7.

• If the matchmarks are aligned or the difference is less than one timing pulley,tooth proceed to step 8.

7. ADJUSTMENT OF CAMSHAFT TIMING PULLEY MARKS

(a) Loosen the idler pulley set bolt a little and shift the idler pulley to the alternator side with a screwdriver and wrench.

(b) Finger tighten the idler pulley set bolt.

(c) Remove the timing belt from the camshaft timing pulleys.

(d) Using SST, rotate the camshaft timing pulley with the camshaft and align the matchmarks.

(f) Loosen the idler pulley set bolt stretch the timing belt.

(g) Tighten the idler pulley set bolt.

NOTE: Make sure that the timing belt tension at A is equal to that at B. If not. retighten the idler pulley set bolt.

(h) Turn the crankshaft clockwise two times and set the No. 1 cylinder to TDC/compression.

NOTE: Recheck the timing belt tension.

(i) Recheck the camshaft timing pulley marks.

CHECK MATCH HOLE OF CAMSHAFT

(a) Clean the camshaft match holes with compressed air.

(b) Align the match hole of the camshaft with that of the camshaft housing by turning the crankshaft pulley.

(c) After alignment, make a note of the crankshaft pulley angle on the No. 1 timing belt cover.

NOTE: Match hole alignment should be done separately for the IN and EX sides.

If the crankshaft pulley angle is within TDC ± 5°, it is correct.

ADJUSTMENT OF CAMSHAFT MATCH HOLES

(a) Using SST to hold the camshaft timing pulley, remove the pulley set bolt.

(b) Make sure that the match hole of camshaft housing is aligned with that of the camshaft.

(c) Using a magnet, remove the match pin from the pin hole of the camshaft timing pulley.

(d) Set the No. 1 cylinder to TDC/compression.

(e) There are three pin holes on the camshaft and timing pulley.

Select one overlapped hole and insert the match 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 then insert the pin.

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

(f) Using SST to hold the camshaft timing pulley, install the pulley set bolt.

SST 09278-54012

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

(g) Turn the crankshaft clockwise two times and set the No. 1 cylinder to TDC/compression,

(h) Recheck the crankshaft pulley angle on the No. 1 timing belt cover after alignment of the camshaft match hole.

10. CHECK TIMING BELT TENSION

(a) Turn both the intake and exhaust camshaft pulleys inward at the same time to slacken the timing belt at position A.

(b) Measure the timing belt tension as shown. Belt deflection at 2 - 3 kg (4.4 - 6.6 lb, 20 - 29 N):

Cold Used belt New belt

Hot (Reference)

5 - 7 mm (0.20 - 0.28 In.) 4 - 6 mm (0.16 - 0.24 In.)

(c) If the measurement is not within specification, adjust with the idler pulley.
