Liberty 4WD V6-3.7L (2009)
Guide both secondary chains through the block and cylinder head openings.
Affix the chains with an elastic strap or equivalent. This will maintain tension on chains to aid in the 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.
Lubricate the idler sprocket bolt washer with oil, install the idler sprocket assembly and tighten the retaining bolt to 34 Nm (25 ft. lbs.).
NOTE: It will be necessary to slightly rotate the camshafts for sprocket installation.
Align the left camshaft sprocket "L" dot to the plated link on the chain.
Align the right camshaft sprocket "R" dot to the plated link on the 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.
Remove the secondary camshaft chain Holder 8429, then attach both sprockets to the camshafts. Remove excess oil from the bolts, then install
sprocket bolts, but do not tighten at this time.
Verify that all plated links are aligned with the marks on all the sprockets and the "V6" marks on the camshaft sprockets are at the 12 o'clock
position.
CAUTION: Ensure the plate between the left secondary chain tensioner and block is correctly installed.
Rotate the engine two full revolutions and verify the timing marks are at the follow locations:
-
Primary chain idler sprocket dot is at 12 o'clock
-
Primary chain crankshaft sprocket dot is at 6 o'clock
-
Secondary chain camshaft sprockets "V6" marks are at 12 o'clock
-
Counter-balancer shaft drive gear dot is aligned to the idler sprocket gear dot
Lubricate all three chains with engine oil.
