Remove the valve covers and the timing chain cover.

Align the crankshaft and camshaft timing marks.

1. Remove the timing chain cover. 2. Align the crankshaft and camshaft timing marks. 3. Mark a reference point on the top chain link and position a ruler over the top of the chain. 4. Attach a torque wrench to the camshaft sprocket bolt and apply 15 ft-lbs of torque in the counterclockwise direction without allowing the crankshaft to rotate. 5. Note the point where your mark aligns on the ruler. 6. Apply 15 ft-lbs of torque in the clockwise direction and note the amount of movement. 7. The measurement is the timing chain deflection. If deflection is more than 1/8-inch, replace the timing chain (see below). 8. Check the tensioner for wear and damage. If tensioner face wear is excessive, replace the tensioner. Before reinstalling the tensioner, it must be retracted (see Step 28). Tighten the tensioner bolts to the torque.

The tensioner is installed to the correct depth when a snap is heard. The tensioner shoe can then be installed, and the plastic clip can be removed with pliers.

Run the engine and check for oil or coolant leaks.

This is a difficult procedure, involving special tools and the removal of the engine from the vehicle. It covers the removal of the timing chain, the cassettes, and the sprockets. It is important to read through both sections and obtain the necessary tools before beginning the procedure.

Tighten the camshaft sprocket bolts to the torque while holding the camshafts in place with a wrench. Do not rely on the camshaft alignment tool to hold the camshafts while tightening the camshaft sprocket bolts to avoid tool and camshaft damage.

Install the timing chain tensioner and tighten it to the torque. Then remove the pin to engage the tensioner to the chain guide.

The left cylinder bank camshaft is driven by a chain at the front of the engine, and the right cylinder bank camshaft is driven by a chain from the rear of the jackshaft. On four-wheel drive models, the balance shaft assembly is driven by a chain from the crankshaft sprocket.

Turn the crankshaft clockwise until the number one piston is at Top Dead Center.

Apply oil to the timing chain and sprockets.

Drape the jack shaft chain over the jack shaft sprocket and engage the chain onto the crankshaft sprocket. Install the jack shaft sprocket onto the jack shaft and tighten the jack shaft sprocket bolt to the torque.

Pry the camshaft forward with a large screwdriver or pry bar between the camshaft sprocket and the block. Note the dial indicator reading and compare with the end play.

Ensure that a straight line passes through the center of the camshaft, the camshaft timing mark (in the 6 o'clock position), the crankshaft timing mark (in the 12 o'clock position), and the center of the crankshaft.
