ENGINE MECHANICAL — Timing Belt

(b) Install the camshaft timing pulleys with the guides facing the directions indicated below.
EX side ...... With the pulley guide facing the No. 2 timing belt cover guide 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 no 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 tensioner torque spring of 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 no pin hole is overlapped, 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.
