INSPECTION OF COMPONENTS
1. Inspect timing belt
(a) Premature parting
^ Check for proper installation.
^ Check the timing belt cover gasket for damage, and check the installation.
(b) If the belt teeth are cracked or damaged, check to see if the camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face, check to see if there are nicks on one side of the idler pulley lock.
(d) If there is wear or damage on only one side of the belt, check the belt guide and the alignment of each pulley.
(e) If there is noticeable wear on the belt teeth, check the timing belt cover gasket for damage and check for correct gasket installation. Check for foreign material on the pulley teeth.
2. Inspect idler pulley and tension spring
(a) Check the turning smoothness of the timing belt idler pulley.
(b) Check the free length of the tension spring.
Free length: 69 mm (2.72 in)
(c) If not as specified, use a new one.
INSTALLATION OF TIMING BELT
1. Install oil pump drive pulley
Using SST to hold the pulley, install and torque the pulley bolt.
SST - 09278-54012
Torque: 220 kg-cm (16 ft-lb. 22 N-m)
2. Install crankshaft timing pulley
Using SST and hammer, drive in the pulley.
SST - 09214-60010
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
Torque: 2,700 kg-cm (195 ft-lb, 265 N-m)
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.
(b) Install the camshaft timing pulleys with the guides facing the directions indicated below.
EX side - With the pulley guide facing the No. timing belt cover side
IN side - With the pulley guide facing the front side
(c) Align the matchmarks of the No.2 timing belt cover with those of the camshaft timing pulleys and of the crankshaft pulley.
NOTE: Make sure that the No. 1 cylinder is set to TDC/ compression.
(d) Install the timing belt with the belt having proper tension between the crankshaft timing pulley and the camshaft timing pulley on the exhaust side.
NOTE: Install the timing belt while the engine is cold.
(e) Loosen the idler pulley set bolt and stretch the timing belt. Torque the idler pulley set bolt.
Torque: 500 kg-cm (36 ft-lb, 49 N-m)
NOTE: Make sure that the timing belt tension at A is equal to that at B.
(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 over- lap it and insert the pin.
^ The crankshaft pulley angle can be adjusted approximately 30 by changing the pin hole to the next one.
(9) Using SST to hold the pulley, install the bolt.
SST - 09278-54012
Torque: 700 kg-cm (51 ft-lb, 69 N-m)
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.
