Camshaft - LH: Camshafts: Installation

WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Lubricate the camshafts with clean engine oil prior to installation.

Install the LH intake and exhaust camshafts in the neutral position. Align the D-slots as shown in the illustration.
Install the 8 camshaft bearing caps and the 16 bolts. Do not tighten the bolts at this time.
Install the LH front camshaft bearing mega cap and the 4 bolts. Do not tighten the bolts at this time
Tighten the bolts in the sequence shown in illustration in 2 stages.
- Stage 1: Tighten to 6 Nm (53 lb-in).
- Stage 2: Tighten an additional 45 degrees.

NOTE: Intake camshaft shown in illustration, exhaust camshaft similar.

Install the VCT system oil filter in the intake and exhaust camshafts.
Install the secondary timing chain onto the LH VCT assemblies. Align the colored links on the secondary timing chain with the timing marks on the VCT assemblies as shown in the illustration.
1. The timing mark on the intake VCT assembly should align between the 2 consecutive colored links.
2. The timing mark on the exhaust VCT assembly should align with the single colored link.
Install the LH VCT assemblies and the secondary timing chain onto the LH camshafts to a position 2 mm (0.078 in) from fully seated. The timing mark on the exhaust VCT assembly should be in the 11 o'clock position.
NOTE: It may be necessary to rotate the exhaust camshaft slightly (using a wrench on the flats of the camshaft) to seat the VCT assemblies onto the camshafts.

Rotate the secondary timing chain tensioner 90 degrees so the ramped area is facing forward and fully seat the VCT assemblies onto the camshafts.
- If the secondary timing chain is not centered over the tensioner, reposition the VCT assemblies until they are fully seated on the camshafts.
NOTE: Use a wrench on the flats of the camshaft to hold the camshafts while tightening the VCT assembly bolts.

Install the 3 LH intake VCT assembly bolts and the 3 LH exhaust VCT assembly bolts.
- Tighten to 15 Nm (133 lb-in) plus an additional 90 degrees.
Install the LH primary timing chain.
- Align the colored link on the timing chain with the timing mark on the LH VCT assembly.
Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain guide. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain guide.

Install the LH timing chain guide and bolt.
- Tighten to 10 Nm (89 lb-in).
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain tensioner arm. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain tensioner arm.

Install the LH timing chain tensioner arm.

NOTE: Complete the following 3 steps on both the LH and RH primary timing chain tensioners.
NOTE: Do not compress the ratchet assembly or damage to the tensioner will occur.

Compress the primary timing chain tensioner plunger, using an edge of a vise.
Using a small screwdriver or pick, push back and hold the ratchet mechanism, then push the ratchet arm back into the tensioner housing.
Install a suitable pin into the hole of the tensioner housing to hold the ratchet assembly and plunger in place during installation.
Install the LH primary timing chain tensioner and 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the holding pin from the tensioner.
Using the crankshaft holding tool, rotate the crankshaft clockwise until the crankshaft keyway is at the 12 o'clock position.
Install the RH primary timing chain.
- Align the colored link on the timing chain with the timing mark on the RH VCT assembly.
Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain guide. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain guide.

Install the RH timing chain guide and bolt.
- Tighten to 10 Nm (89 lb-in).
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain tensioner arm. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain tensioner arm.

Install the RH timing chain tensioner arm.
Install the RH primary timing chain tensioner and 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the holding pin from the tensioner.
With the crankshaft keyway still at the 12 o'clock position, verify the timing mark alignment is correct.
