  1. Install the left timing chain guide (4). Torque fastener to 28 N.m ( 250 in. lbs.). See Fig 1.
  2. Install the right timing chain guide (3). Torque fastener to 28 N.m ( 250 in. lbs.). See Fig 1.
    NOTE: When installing the timing chain, ensure the plated links on the timing chain are aligned with the timing marks on the crankshaft and camshaft sprockets. If a timing chain is being re-used, and the plating is wore off the chain, the links also have machined dimples. See Fig 1.
  3. Feed the timing chain through the opening in the top of the cylinder head.
  4. Install the timing chain around the crankshaft sprocket, aligning the two plated links with the crankshaft sprocket timing marks. See Fig 1.
  5. Install the timing chain around the camshaft sprocket, aligning the single plated link with the camshaft sprocket timing mark. See Fig 1.
  6. Install the camshaft sprocket on the camshaft.
    CAUTION: DO NOT use an impact wrench (or any other air operated tool) for tightening the camshaft sprocket bolt. Damage to the camshaft timing pin can result. ONLY use a hand wrench while holding camshaft sprocket with Special Tool.
  7. Install camshaft sprocket bolt. While holding the camshaft sprocket with Special Tool 8435, torque bolt to 115 N.m (85 ft. lbs.).
