Timing Component Alignment Marks: Locations

Timing Alignment

Timing Drive Components - Roller Primary Timing Chain With Composite RH Guide









Timing Drive Components - Roller Primary Timing Chain With Stamped Steel RH Guide









Timing Drive Components - Inverted Tooth Primary Timing Chain









NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan may cause engine failure.

NOTE: The engine comes equipped with either a roller primary timing chain or an inverted tooth primary timing chain. The roller timing chain engine comes equipped with either a composite RH timing chain guide requiring the timing chain to ride on the outer side of the guide or a stamped steel RH timing chain guide requiring the timing chain to ride on the inner side of the guide. All roller timing chain engine replacement RH timing chain guides will be the stamped steel design.

ALL ENGINES

Assemble the RH VCT assembly, the RH exhaust camshaft sprocket and the RH secondary timing chain.
- Align the colored links with the timing marks.





Position the RH secondary timing assembly onto the camshafts.





Assemble the LH VCT assembly, the LH exhaust camshaft sprocket and the LH secondary timing chain.
- Align the colored links with the timing marks.





Position the LH secondary timing assembly onto the camshafts.





ENGINE EQUIPPED WITH AN INVERTED TOOTH TIMING CHAIN

Install the crankshaft timing chain sprocket.





NOTE: The crankshaft sprocket timing mark should be between the 2 colored links.

Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.





As a post-check, verify correct alignment of all timing marks.
- There are 48 links between the RH intake VCT assembly colored link (1) and the LH intake VCT assembly colored link (2).

- There are 35 links between the LH intake VCT assembly colored link (2) and the 2 crankshaft sprockets colored links (3).





ENGINE EQUIPPED WITH A ROLLER TIMING CHAIN

Install the crankshaft timing chain sprocket.





Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.





As a post-check, verify correct alignment of all timing marks.
- There are 38 links between the RH intake VCT assembly colored link (1) and the LH intake VCT assembly colored link (2).

- There are 27 links between the LH intake VCT assembly colored link (2) and the crankshaft sprocket colored link (3).
