7. Install both secondary chains onto the idler sprocket (2). Align two plated links on the secondary chains to be visible through the two lower
openings on the idler sprocket (4 o'clock and 8 o'clock). Once the secondary timing chains are installed, position special tool 8429 (1) to hold
chains in place for installation.
8. Align primary chain double plated links with the timing mark at 12 o'clock on the idler sprocket. Align the primary chain single plated link with
the timing mark at 6 o'clock on the crankshaft sprocket.
9. Lubricate idler shaft and bushings with clean engine oil.
NOTE: The idler sprocket must be timed to the counterbalance shaft drive gear before the idler sprocket is fully seated.
10. Install all chains, crankshaft sprocket, and idler sprocket as an assembly. After guiding both secondary chains through the block and cylinder head
openings, affix chains with a elastic strap or equivalent. This will maintain tension on chains to aid in installation. Align the timing mark (2) on the
idler sprocket gear (3) to the timing mark on the counterbalance shaft drive gear (1), then seat idler sprocket fully. Before installing idler sprocket
bolt, lubricate washer with oil, and tighten idler sprocket assembly retaining bolt to 34 Nm (25 ft. lbs.).
NOTE: It will be necessary to slightly rotate camshafts for sprocket installation.
11. Align left camshaft sprocket L dot to plated link on chain.
12. Align right camshaft sprocket R dot to plated link on chain.
CAUTION: Remove excess oil from the camshaft sprocket bolt. Failure to do so can result in over-torque of bolt resulting in bolt failure.
13. Remove Special Tool 8429, then attach both sprockets to camshafts. Remove excess oil from bolts, then Install sprocket bolts, but do not tighten at
this time.
14. Verify that all plated links are aligned with the marks on all sprockets and the V6 marks on camshaft sprockets are at the 12 o'clock position.
CAUTION: Ensure the plate between the left secondary chain tensioner and block is correctly installed.
