Timing Drive Components: Installation

WARNING: This page is about a different car, the 2010 Mercury Milan and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Install the crankshaft sprocket with the timing mark facing out. The timing mark on the LH and RH timing chains will be aligned to this mark during assembly.
NOTE: Failure to verify correct timing drive component alignment will result in severe engine damage.

NOTE: LH shown, RH similar.
Slowly compress the timing chain tensioner.
NOTE: During tensioner compression, do not release the ratchet stem until the tensioner piston is fully bottomed in its bore or damage to the ratchet stem will result.
Retain the tensioner piston with a 1.5 mm (0.06 in) diameter wire or paper clip.

If timing marks in the timing chains are not evident, use a permanent-type marker to mark the crankshaft and camshaft timing marks on the LH and RH timing chains.
1. Mark any link to use as the crankshaft timing mark.
2. Starting with the crankshaft timing mark, count 29 links and mark the link.
3. Continue counting to link 42 and mark the link.

Remove the LH and RH timing chain tensioner piston retaining wires.
Rotate the crankshaft counterclockwise 120 degrees to TDC .
Verify the timing with the following steps.
1. There should be 12 chain links between the camshaft timing marks.
2. There should be 27 chain links between the camshaft and the crankshaft timing marks.
3. There should be 30 chain links between the camshaft and the crankshaft timing marks.
NOTE: Failure to verify correct timing drive component alignment will result in severe engine damage.
