Section 15 (2.7L Engine (Service Information)): Camshaft(S): Installation
WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When the timing chain is removed and the cylinder heads are installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.
- Assemble camshaft chain on the cams. Verify that plated links (1) are facing toward the front. Align the plated links (1) to the dots (4) on the camshaft sprockets.
- If camshaft chain tensioner is already in the compressed and locked position, proceed to step #4.
- When the camshaft chain tensioner is removed, it is necessary to compress and lock the tensioner using the following procedures:
- Place tensioner (1) into a soft jaw vise.
- SLOWLY compress tensioner until fabricated lock pin (2) or the equivalent can be inserted into the locking holes.
- Remove compressed and locked tensioner from the vise.
- Insert the compressed and locked camshaft chain tensioner (2) in between the camshafts and chain.
- Rotate the cams so that the plated links (1) and dots (4) are facing the 12:00 o'clock position.
- Install cams to cylinder head. Verify that rocker arms are correctly seated and in proper positions.
- Install camshaft bearing caps. Verify that bearing caps are installed in same position as removed.
- Tighten cam bearing cap bolts gradually in sequence shown in Fig 4 to 12 N.m (105 in. lbs.).
- Install secondary chain tensioner (2) bolts and tighten to 12 N.m (105 in. lbs.).
- Remove locking pin (3) from secondary tensioners (2).
- Measure camshafts end play (Refer to STANDARD PROCEDURE - Cylinder Head Oil Gallery Cup Plug Service ).
- Install the primary timing chain (Refer to ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND SPROCKETS - INSTALLATION) .
