INSTALLATION CAUTION / NOTICE / HINT HINT: Perform " Inspection After Repairs" after replacing the No. 3 or No. 4 camshaft or camshaft timing gear LH or camshaft timing exhaust gear LH (See page ). PROCEDURE 1. INSTALL CAMSHAFT BEARING CAP LH HINT: Perform "Inspection After Repairs" after replacing the No. 3 or No. 4 camshaft (See page ).
(b) Install the No. 3 and No. 4 camshafts to the camshaft housing. (c) Confirm the marks and numbers on the camshaft bearing caps and place them in their proper positions and directions.
2. INSTALL CAMSHAFT HOUSING SUB-ASSEMBLY LH
3. INSTALL NO. 3 CHAIN TENSIONER ASSEMBLY (a) Install the chain tensioner with the 2 bolts. Torque: 10 N·m {102 kgf·cm, 7 ft·lbf} (b) While pushing down the No. 2 chain tensioner, insert a pin of φ1.0 mm (0.0394 in.) into the hole to fix it in place. 4. INSTALL NO. 1 CHAIN SUB-ASSEMBLY LH HINT: Perform "Inspection After Repairs" after replacing the camshaft timing gear LH or camshaft timing exhaust gear LH (See page ).
(d) Install the crankshaft timing sprocket to the crankshaft. (e) Align and attach the knock pin of the No. 3 camshaft with the pin hole of the camshaft timing gear. (f) Using the hexagonal portion of the No. 4 camshaft, align and attach the knock pin of the No. 4 camshaft with the pin hole of the camshaft timing exhaust gear. NOTICE: Because the gears' timing mark positions may shift due to looseness of the No. 1 chain, use the hexagonal portion of the camshaft to hold the No. 3 camshaft in place until the No. 1 chain tensioner is installed. (g) Remove the pin from the No. 2 chain tensioner. 5. INSTALL NO. 1 CHAIN TENSIONER SLIPPER LH HINT: If you cannot install the chain tensioner slipper due to the tension of the chain, use the hexagonal portion of the camshaft to loosen the chain and install the chain tensioner. 6. INSTALL NO. 1 CHAIN TENSIONER ASSEMBLY LH (a) Move the stopper plate upward to release the lock, and push the plunger deep into the tensioner. (b) Move the stopper plate downward to set the lock, and insert a hexagon wrench into the hole of the stopper plate.
7. INSTALL NO. 1 CHAIN VIBRATION DAMPER LH (a) Install the vibration damper with the 2 bolts. Torque: 21 N·m {214 kgf·cm, 15 ft·lbf} (b) Remove the hexagon wrench from the No. 1 chain tensioner. 8. TIGHTEN CAMSHAFT TIMING GEAR LH
9. CHECK NO. 1 CYLINDER TO TDC / COMPRESSION
10. INSTALL TIMING CHAIN COVER SUB-ASSEMBLY (a) Install the timing chain cover (See page ). 11. INSPECT IGNITION TIMING
12. INSPECT ENGINE IDLE SPEED
