Installation
Timing Drive ComponentsInstallation
1. Install the crankshaft sprockets with the timing marks out.
2. NOTE: LH shown, RH similar.
Position the chain tensioner in a soft-jawed vise.
3. NOTE: LH shown, RH similar.
Hold the chain tensioner ratchet lock mechanism away from the ratchet stem with a small pick.
4. CAUTION: During tensioner compression, do not release the ratchet stem until the tensioner piston is fully bottomed in its bore or damage to the ratchet stem will result.
Slowly compress the timing chain tensioner.
5. Retain the tensioner piston with a 1.5 mm (0.05 inch) wire or paper clip.
6. If timing marks in the timing chains are not evident, use a permanent-type marker to mark the crankshaft and camshaft timing marks on the LH and RH timing chains.
1 Mark any link to use as the crankshaft timing mark.
2 Starting with the crankshaft timing mark, count counterclockwise 29 links and mark the link.
3 Continue counting counterclockwise to link 42 and mark the link.
7. Verify that the LH camshafts are correctly positioned.
8. Install the VCT assembly and the 4 bolts.
^ Tighten to 25 Nm (18 lb-ft).
9. Install the LH timing chain.
^ Align the marks on the timing chain with the marks on the camshaft and crankshaft sprockets.
10. Install the LH timing chain tensioner arm and the LH timing chain tensioner.
1 Install the tensioner arm.
2 Position the tensioner.
3 Install the 2 bolts.
^ Tighten to 25 Nm (18 lb-ft).
11. Install the crankshaft pulley bolt and washer and rotate the crankshaft clockwise 120 degrees until the crankshaft keyway is in the 3 o'clock position.
12. Verify that the RH camshafts are correctly positioned.
13. Install the RH VCT assembly and the 3 bolts.
^ Tighten to 25 Nm (18 lb-ft).
14. Install the RH timing chain.
^ Align the marks on the timing chain with the marks on the camshaft and crankshaft sprockets.
15. Install the RH timing chain tensioner and tensioner arm.
1 Install the tensioner arm.
2 Position the tensioner.
3 Install the 2 bolts.
^ Tighten to 25 Nm (18 lb-ft).
16. Remove the LH and RH timing chain tensioner piston retaining wires.
17. Rotate the crankshaft counterclockwise 120 degrees to TDC.
18. CAUTION: Failure to verify correct timing drive component alignment will result in severe engine damage.
Verify the timing with the following steps.
1 There should be 12 chain links between the camshaft timing marks.
2 There should be 27 chain links between the camshaft and the crankshaft timing marks.
3 There should be 30 chain links between the camshaft and the crankshaft timing marks.
19. Remove the crankshaft pulley bolt and washer.
20. NOTE: This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped 30RFF (orange in color).
Install the ignition pulse wheel.
21. CAUTION: Only use hand tools when removing or installing the spark plugs or damage can occur to the cylinder head or spark plug.
Install the 6 spark plugs (1 shown).
^ Tighten to 15 Nm (11 lb-ft).
22. Install the engine front cover.
