TIMING CHAIN

NOTE Refer to "Liquid Gasket Application Procedure"
Service and Repair
Before installation, wipe off the protruding sealant.

CAUTION: After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike piston heads.
When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting surfaces with new engine oil.
Apply new engine oil to bolt threads and seat surfaces when installing camshaft sprockets and crankshaft pulley
Before disconnecting fuel hose, release fuel pressure.
GBe careful not to damage sensor edges.
Do not spill engine coolant on drive belts.

REMOVAL

Removal
1. Release fuel pressure.
2. Remove battery.
3. Remove radiator.
4. Drain engine oil.
5. Remove drive belts and idler pulley with brackets.
6. Remove cooling fan with bracket.
7. Remove engine cover.
8. Remove air duct with air cleaner case, collector, blow-by hose, vacuum hoses, fuel hoses, water hoses, wires, harnesses, connectors and so on.
9. Remove the air compressor, and tie it down using rope or the like to keep it from interfering.
10. Remove the power steering oil pump and reservoir tank. Tie them down using rope or the like to keep them from interfering.
11. Remove alternator.
12. Remove the following.
- Vacuum gallery
- Water bypass pipe
- Brackets









13. Remove camshaft position sensor (PHASE), intake valve timing control position sensors and crankshaft position sensor (REF).
- Avoid impact such as dropping.
- Do not disassemble the components.
- Do not place them on areas where iron powder may adhere.
- Keep away from the objects susceptible to magnetism.






14. Remove upper intake manifold collector in reverse order of installation.






15. Remove intake manifold collector support bolts.






16. Remove lower intake manifold collector in reverse order of installation.






17. Disconnect injector harness connectors.
18. Remove fuel tube assembly in reverse order of installation.
19. Remove ignition coils.






20. Remove RH and LH rocker covers from cylinder head.
21. Set No. 1 piston at TDC on the compression stroke by rotating crankshaft.






Align pointer with TDC mark on crankshaft pulley.





Check that intake and exhaust cam nose on No. 1 cylinder are installed as shown. If not, turn the crankshaft one revolution (360°) and align as above.






22. Remove starter motor, and set ring gear stopper using the mounting bolt hole.
Be careful not to damage the signal plate teeth.






23. Loosen the crankshaft pulley bolt.






24. Remove crankshaft pulley with a suitable puller.
25. Remove aluminum oil pan.
26. Temporarily install the suspension member bolts and engine mounting nuts.
27. Remove intake valve timing control valve covers.






Loosen bolts in numerical order as shown in the figure.
In the cover, the shaft is engaged with the center hole of the intake cam sprocket. Remove it straight out until the engagement comes off.

28. Remove front timing chain case bolts.






Loosen bolts in numerical order as shown in the figure.





29. Remove front timing chain case.
Do not scratch sealing surfaces.






30. Remove internal chain guide.
31. Remove upper tension guide.
32. Remove timing chain tensioner and slack guide.






Remove timing chain tensioner. (Push piston and insert a suitable pin into pinhole.)






33. Attach a suitable stopper pin to RH and LH camshaft chain tensioners.






34. Remove intake and exhaust camshaft sprocket bolts.
- Apply paint to timing chain and camshaft sprockets for alignment during installation.
- Secure the hexagonal head of the camshaft using a spanner to loosen mounting bolts.






35. Remove primary and secondary timing chains along with the camshaft sprockets.
- Do not disassemble the intake camshaft sprocket.
- Avoid damaging the signal mark protrusion area at the front of the left bank intake camshaft sprocket. Keep it away from magnetized objects.






36. Remove lower chain guide.
37. Remove crankshaft sprocket.






38. Use a scraper to remove all traces of liquid gasket from front timing chain case.






Remove old liquid gasket from the bolt hole and thread.






39. Use a scraper to remove all traces of liquid gasket from intake valve timing control valve cover.







Inspection
Check for cracks and excessive wear at roller links. Replace chain if necessary.
