Timing Chain: Testing and Inspection
Cam Chain Inspection1. Remove the front wheels.
2. Remove the splash shield.
3. Remove the drive belt.
4. Remove the cylinder head cover.
5. Set the No. 1 piston at top dead center (TDC). The punch mark on the variable valve timing control (VTC) actuator and the punch mark on the exhaust camshaft sprocket should be at the top. Align the TDC marks on the VTC actuator and exhaust camshaft sprocket.
6. Disconnect the crankshaft position (CKP) sensor connector and VTC oil control solenoid valve connector.
7. Remove the VTC oil control solenoid valve.
8. Remove the crankshaft pulley.
9. Support the engine with a jack and a wood block under the oil pan.
10. Remove the upper torque rod.
11. Remove the ground cable, then remove the side engine mount bracket.
12. Remove the side engine mount bracket mounting bolts.
13. Remove the cam chain case and side engine mount bracket.
14. Measure the tensioner rod length between the tensioner body and bottom of the flat surface section on the tensioner rod. If the length is more than the service limit, replace the cam chain and the oil pump chain.
15. Check the chain case oil seal for damage. If the oil seal is damaged, replace the chain case oil seal.
16. Remove all of the old liquid gasket from the chain case mating surfaces, bolts, and bolt holes.
17. Clean and dry the chain case mating surfaces.
18. Apply liquid gasket, P/N 08717-0004, 08718,0001, 08718-0003, or 08718-0009, evenly to the engine block mating surface of the chain case. Install the component within 5 minutes of applying the liquid gasket.
NOTE:
^ If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
^ If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
19. Apply liquid gasket to the engine block upper surface contact areas on the chain case and lower block upper surface contact areas on the chain case.
20. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the oil pan mating surface of the chain case. Install the component within 5 minutes of applying the liquid gasket.
NOTE:
^ If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
^ If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
21. Install the new O-ring, side engine mount bracket, and mounting bolts on the chain case. Set the edge of the chain case to the edge of the oil pan, then install the chain case on the engine block. Wipe off the excess liquid gasket on the oil pan and chain case mating area.
NOTE:
^ When installing the chain case, do not slide the bottom surface onto the oil pan mounting surface.
^ Wait at least 30 minutes before filling the engine with oil.
^ Do not run the engine for at least 3 hours after installing the chain case.
22. Tighten the side engine mount bracket mounting bolts.
23. Install the side engine mount bracket, then loosely tighten the new bolt and nut, and loosely tighten the bolt. Install the ground cable.
24. Remove the air cleaner housing assembly.
25. Loosen the transmission mounting bolt and nuts.
26. Raise the lift to full height.
27. Loosen the lower torque rod mounting bolt.
28. Lower the vehicle on the lift.
29. Tighten the side engine mount mounting bolts and nut.
30. Tighten the transmission mounting bolt and nuts.
31. Raise the lift to full height.
32. Tighten the lower torque rod mounting bolt.
33. Lower the vehicle on the lift.
34. Install the air cleaner housing assembly.
35. Install the upper torque rod, then tighten the new upper torque rod mounting bolts in the numbered sequence shown.
36. Install the VTC oil control solenoid valve.
37. Connect the CKP sensor connector and VTC oil control solenoid valve connector.
38. Install the crankshaft pulley.
39. Install the cylinder head cover.
40. Install the drive belt.
41. Do the CKP pattern clear/CKP learn procedure.
