1. Tighten exhaust manifold nuts to specification in two stages in
the numerical order shown.
2. Use Tool (A) to install the air fuel ratio sensor 1. CAUTION:
• Handle it carefully and avoid impacts.
• Before installing a new air fu el ratio sensor 1, clean the
exhaust tube threads using suitable tool and approved
anti-seize lubricant.
• Do not over-tighten the air fu el ratio sensor 1. Doing so
may damage the air fuel rati o sensor 1, resulting in the
MIL coming on. : Engine front ALBIA0625ZZ

a. Loosen bolts in the reverse of the order shown.
b. Cut liquid gasket by prying the position ( ) shown, and then remove the front cover.
10. Remove camshaft position sensor (PHASE) from rear end of cylinder head. CAUTION:
Handle it carefully and avoid impacts.
11. Remove camshaft sprocket (EXH) (1). CAUTION:
• Hold the camshaft hexagonal part (A), and then secure the
camshaft.
• Never rotate crankshaft and camshaft separately, so as not to contact valve with pist on in the following steps.
12. Turn the camshaft sprocket (INT) to the most advanced position. CAUTION:
Installation and removal of the camshaft sprocket (INT) must be done in the most advanced posi-
tion for the following reasons. KBIA3429J

c. Tighten bolts in the numerical order shown.
d. After all bolts are tightened, retighten them to specified torque in numerical order as shown.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking to
surface.
22. Insert crankshaft pulley by aligning with crankshaft key. • When inserting crankshaft pulley with a plastic hamme r, tap on its center portion (not circumference).
CAUTION:
Never damage front oil seal lip section.
23. Tighten crankshaft pulley bolt with the following procedure: • Secure crankshaft pulley with a suitable tool, and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark (B) on crankshaft pulley, mating with any one of six easy to recognize angle marks (A) on crankshaft bolt flange
(1).
d. Turn another 60 degrees clockwise (angle tightening). • Check the tightening angle with movement of one angle mark.
24. Make sure that crankshaft turns smoothly by rotating by hand clockwise.
25. Install the camshaft position sensor (PHASE) to the rear end of cylinder head.
