2AZ-FE ENGINE MECHANICAL: CAMSHAFT: REMOVAL

REMOVAL

1. REMOVE FRONT WHEEL RH
2. REMOVE ENGINE UNDER COVER LH
3. REMOVE ENGINE UNDER COVER RH
4. REMOVE FRONT FENDER APRON SEAL RH
5. REMOVE NO. 1 ENGINE COVER SUB-ASSEMBLY Removal
6. REMOVE IGNITION COIL ASSEMBLY Removal
7. REMOVE CYLINDER HEAD COVER SUB-ASSEMBLY Removal
8. SET NO. 1 CYLINDER TO TDC/COMPRESSION





(a) Turn the crankshaft pulley until the groove and the timing mark "0" on the timing chain cover are aligned.
(b) Check that each timing mark on the camshaft timing gear and sprocket is aligned with each timing mark located on the No. 1 and No. 2 bearing caps as shown in the illustration.
If not, turn the crankshaft pulley 1 revolution (360°) to align the timing marks as illustrated.
(c) Place paint marks on the chain in alignment with the timing marks on the camshaft timing gear and camshaft timing sprocket.
9. REMOVE NO. 1 CHAIN TENSIONER ASSEMBLY Removal
10. REMOVE NO. 2 CAMSHAFT





(a) While holding the camshaft with a wrench, loosen the camshaft timing set bolt.





(b) Using several steps, uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration.
(c) Remove the 5 bearing caps.





(d) While holding the No. 2 camshaft by hand, remove the camshaft timing sprocket set bolt.
(e) Remove the camshaft timing sprocket from the No. 2 camshaft with the timing chain wrapped on the sprocket.
(f) Remove the camshaft timing sprocket from the timing chain.
11. REMOVE CAMSHAFT





(a) Using several steps, uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration.
(b) Remove the 5 bearing caps.
(c) Remove the camshaft and camshaft timing gear while holding the timing chain by hand.





(d) Support the timing chain with a string to prevent it from slipping off the crankshaft sprocket as shown in the illustration.
NOTICE: Be careful not to drop anything inside the timing chain cover.

12. REMOVE CAMSHAFT TIMING GEAR ASSEMBLY





(a) Clamp the camshaft in a vise, and make sure that the camshaft timing gear does not rotate.
(b) Cover all the oil ports except the advance side port shown in the illustration with vinyl tape.





(c) Apply air pressure of 100 kPa (1.0 kgf/cm2, 14 psi) to the opened oil path, then turn the camshaft timing gear in the advance direction (counterclockwise) by hand.
CAUTION: Cover the paths with a piece of cloth to avoid oil splashes.
HINT: Depending on the air pressure, the camshaft timing gear will turn to the advance side without applying force by hand. Also, if enough air pressure cannot be applied because of air leakage from the path, releasing the lock pin may be difficult.





(d) Remove the flange bolt of the camshaft timing gear.
NOTICE:
- Be sure not to remove the other 4 bolts.
- If planning to reuse the gear, be sure to release the straight pin lock before installing the gear.
