Timing Drive Components: Installation
- Compress the tensioner plunger, using a vise.
- Install a retaining clip on the tensioner to hold the plunger in place during installation.
- If the copper links are not visible, mark one link on one end and one link on the other end, and use as timing marks.
- Rotate the RH camshaft sprocket until the timing mark is approximately at the 11 o'clock position. Rotate the LH camshaft sprocket until the timing mark is approximately at the 12 o'clock position.
- Install special tools from the camshaft.
- Install the crankshaft sprocket, making sure the flange faces forward.
- Install the timing chain guide.
- Position the LH timing chain guide.
- Install and tighten the LH bolts.
- Position the RH timing chain guide.
- Install and tighten the RH bolts.
- Using the special tool, position the crankshaft so the number one cylinder is at TDC.
- Remove the special tool.
- Position the LH (inner) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.
- Install the LH timing chain on the camshaft sprocket, aligning the copper (marked) link with the timing marks on the sprocket.
- Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner.
- Remove the retaining clip from the LH timing chain tensioner.
- Position the RH (outer) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.
- Install the RH timing chain on the camshaft sprocket, aligning the copper (marked) link with the timing marks on the sprocket.
- Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner.
- Remove the retaining clip from the RH timing chain tensioner.
- Make sure that the copper (marked) chain links are lined up with the dots on the crankshaft sprockets and the camshaft sprocket.
- Remove special tools from the camshaft.
- Install the crankshaft sensor ring on the crankshaft.
- Install the roller followers. For additional information, see CAMSHAFT ROLLER FOLLOWER .
- Install the engine front cover. For additional information, see ENGINE FRONT COVER .
CAUTION:
Timing chain procedures must be followed exactly or damage to valves and pistons will result.
CAUTION:
Unless otherwise instructed, do not rotate either the crankshaft or the camshafts, when the timing chains are removed and the cylinder heads are installed. Severe piston and valve damage will occur.
CAUTION:
When instructed to do so, rotate the crankshaft counterclockwise only. Do not rotate past the position shown or severe piston and valve damage can occur.
NOTE:
The number one cylinder is at top dead center (TDC) when the stud on the engine block fits into the slot in the handle of the special tool.
NOTE:
The LH timing chain tensioner arm has a bump near the dowel hole for identification.
