Removal - Right Camshaft
- Remove the cylinder head cover(s) (1). Refer to COVER(S), CYLINDER HEAD, REMOVAL, 4.7L .CAUTION:
When the timing chain is removed and the cylinder heads are still installed, Do not forcefully rotate the camshafts or crankshaft independently of each other. Severe valve and/or piston damage can occur.
- Set #1 cylinder to TDC and align the camshaft sprocket V8 mark (1) to the 12 o'clock position.
- Mark the link on the secondary timing chain that is aligned with the two dots (2) on the camshaft sprocket as shown in the illustration to aid in installation.
CAUTION:
Do not hold or pry on the camshaft target wheel for any reason, severe damage will occur to the target wheel resulting in a vehicle no start condition.
CAUTION:When removing the camshaft sprocket, timing chains or camshaft, the timing chain tensioner must be secured, failure to use Locking Wedge will result in hydraulic tensioner ratchet over extension, requiring timing chain cover removal to reset the tensioner ratchet.
CAUTION:Do not force Locking Wedge past the narrowest point between the chain strands. Damage to the tensioners may occur.
- Position Locking Wedge (special tool #9867, Wedge, Locking) (2) between the timing chain strands (1), gently tap the wedge into position and secure the timing chain against the tensioner arm and guide.
- Using Spanner Wrench (special tool #6958, Wrench, Spanner) (2) with Adapter Pins (special tool #8346, Pins, Adapter), secure the camshaft sprocket (3) and remove the camshaft sprocket bolt.
- Disconnect the electrical connector to the Camshaft Position Sensor (CMP).
- Remove the CMP sensor retaining bolt
- Using a slight rocking motion, carefully remove the CMP sensor (1).
- Check the condition of the CMP sensor O-ring, replace as necessary.
- Position Camshaft Holder (special tool #8428A, Holder, Camshaft) (1) onto the camshaft (3).
- Using Camshaft Holder (special tool #8428A, Holder, Camshaft) (1), hold the camshaft while removing the camshaft sprocket (2).
- Using Camshaft Holder (special tool #8428A, Holder, Camshaft) (1), gently allow the camshaft to rotate 45° counterclockwise until the camshaft is in the neutral position (no valve load).
