Timing Drive Components: Installation
WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Timing chain procedures must be followed exactly or damage to valves and pistons will result.
- Compress the tensioner plunger, using a vise.
- Install a retaining clip on the tensioner to hold the plunger in during installation.
- If copper links are not visible, mark two links on one end and one link on the other end, and use as timing marks.
- On engines equipped with bolt-on sprockets, install the camshaft sprocket (2).
- Install the bolt (1).
- Tighten the bolt.
- M10 bolt: Tighten in two stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten an additional 90 degrees.
- M12 bolt: Tighten to 120 Nm (90 lb-ft).
- M10 bolt: Tighten in two stages.
- Install the timing chain guides.
- Preposition the camshafts.
- Rotate the LH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 12 o'clock.
- Rotate the RH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 11 o'clock.
- Tighten the Camshaft Holding Tool to maintain camshaft prepositioning.
- Position the crankshaft with the special tool, then remove the tool.
- Install the crankshaft sprocket, making sure the flange faces forward.
- Install the lower end of the LH timing chain, aligning the timing marks.
- Install the LH timing chain on the camshaft sprocket with the two chain (marked) links and the timing marks aligned.
- Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner.
- Install the RH (outer) timing chain on the crankshaft sprocket.
- Position the timing chain on the camshaft sprocket. Make sure the two copper-colored (marked) links align with the camshaft sprocket timing mark.
- Position the LH and RH timing chain tensioner arms on the dowel pins. Position the timing chain tensioners and install the bolts.
- Remove the retaining clips from the RH and LH timing chain tensioners.
- Check for correct alignment of all timing marks.
- Remove the special tools from the camshafts.
- Install the crankshaft sensor ring on the crankshaft.
- Lubricate the balance shaft journals with clean engine oil.
- Using the index mark on the balance shaft, mark the corresponding gear tooth with chalk.
- Position the balance shaft on the journals.
- Align the chalk mark on the balance shaft with the camshaft timing mark as shown.
- Install the bearing caps in their original locations. Install the bolts and tighten the bolts in the sequence shown.
- Install engine front cover. For additional information, refer to ENGINE FRONT COVER .
CAUTION:
Timing chain procedures must be followed exactly or damage to valves and pistons will result.
NOTE:
There are 61 links in each timing chain.
NOTE:
Slightly loosen the Camshaft Holding Tool to allow slight camshaft movement.
CAUTION:
Rotate the crankshaft counterclockwise only. Do not rotate past the position shown 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. If necessary, use the Camshaft Positioning Tool to adjust.

NOTE:
The LH timing chain tensioner arm has a bump near the dowel hole for identification.
CAUTION:
The camshaft sprocket can jump time if the Camshaft Holding Tool is not secured.
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:
The LH timing chain tensioner arm has a bump near the dowel hole, for identification.
NOTE:
It may be necessary to use an inspection mirror to see the marks.
