- Tighten to 25 Nm (18 lb-ft).
- Install the RH (outer) timing chain on the crankshaft sprocket.
- Position the timing chain on the camshaft sprocket. Make sure the 2 copper-colored (marked) links align with the camshaft sprocket timing mark.
- Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner and the 2 bolts.
- Tighten to 25 Nm (18 lb-ft).
- Remove the Hydraulic Chain Tensioner Retaining Clips from the RH and LH timing chain tensioners.
- Check for correct alignment of all timing marks.
- Install the crankshaft sensor ring on the crankshaft.
- Tighten the RH camshaft sprocket bolt in 2 stages:
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten an additional 90 degrees.
- Tighten the LH camshaft sprocket bolt in 2 stages:
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten an additional 90 degrees.
- Rotate the crankshaft clockwise and position the crankshaft keyway at the 6 o'clock position.
- Remove the 2 bolts and the middle balance shaft bearing support and camshaft bearing cap assembly.
- Using the Valve Spring Compressor, install the roller follower.
- Lubricate the camshaft roller follower with clean engine oil prior to installation.
- Position the camshaft bearing cap and install the bolts in 2 stages:
- Stage 1: Tighten to 8 Nm (71 lb-in).
- Stage 2: Tighten an additional 45 degrees.
- Remove the 2 bolts and the rear balance shaft bearing support and camshaft bearing cap assembly.
- Using the Valve Spring Compressor, install the roller follower.
- Lubricate the camshaft roller follower with clean engine oil prior to installation.
- Position the camshaft bearing cap and install the bolts in 2 stages:
- Stage 1: Tighten to 8 Nm (71 lb-in).
- Stage 2: Tighten an additional 45 degrees.
- Using the Valve Spring Compressor, install all of the remaining camshaft roller followers.
- Lubricate the camshaft roller followers with clean engine oil prior to installation.
- Rotate the crankshaft counterclockwise and position the crankshaft keyway at the 11 o'clock position.
- Lubricate the balance shaft journals with clean engine oil.
- Position the balance shaft on the journals and align the timing mark on the balance shaft with the camshaft timing mark as shown in illustration.
- Position the 3 balance shaft bearing caps and install the 6 bolts and tighten in the sequence shown in illustration.
- Tighten to 10 Nm (89 lb-in).
- Install engine front cover. For additional information, refer to Engine Front Cover .
NOTE:
If the components are to be reinstalled, they must be installed into their original locations or engine damage may occur.
NOTE:
Camshaft shown in illustration installed to clarify camshaft roller follower position.
NOTE:
Lubricate the camshaft roller followers with clean engine oil prior to installation.
NOTE:
If the components are to be reinstalled, they must be installed into their original locations or engine damage may occur.
NOTE:
Camshaft shown in illustration installed to clarify camshaft roller follower position.
NOTE:
Lubricate the camshaft roller followers prior to installation.
NOTE:
Timing chain procedures must be followed exactly or damage to valves and pistons will result.
NOTE:
Prior to installation, inspect the tensioner-sealing bead for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner or engine damage may occur.
NOTE:
There are 61 links in each timing chain.
NOTE:
Rotate the crankshaft counterclockwise only. Do not rotate past the position shown in illustration or severe piston and/or valve damage can occur.
NOTE:
Be sure the upper half of the timing chain is below the tensioner guide dowel.
NOTE:
The LH timing chain tensioner arm has a bump near the dowel hole for identification.
NOTE:
Be sure the chain link and crankshaft sprocket timing marks are aligned.
NOTE:
The lower half of the timing chain must be positioned above the dowel.
NOTE:
Only use hand tools to tighten the camshaft sprocket bolt or damage may occur to the camshaft or camshaft sprocket.
NOTE:
Only use hand tools to tighten the camshaft sprocket bolt or damage may occur to the camshaft or camshaft sprocket.
NOTE:
If the components are to be reinstalled, they must be installed into their original locations or damage to the engine may occur.
NOTE:
Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed. For additional information, refer to Cylinder Head .
