Timing Component Alignment Marks: Locations

NOTE:
- Align the matching marks on timing chain (secondary) (orange link) with the ones on intake and exhaust camshaft sprockets (punched), and install them.

NOTE:
- Matching marks for camshaft sprockets (INT) are on the back side of camshaft sprockets (secondary).
- There are two types of matching marks, the circle and oval types. They should be used for the bank 1 and bank 2, respectively.

Bank 1 : Use circle type
Bank 2 : Use oval type




- Check that the matching marks on crankshaft sprocket face the front of the engine.
b. Install timing chain (primary).
Install timing chain (primary) so that the matching mark (punched) (B) on camshaft sprocket (INT) (1) is aligned with the yellow link (A) on timing chain, while the matching mark (notched) (C) on crankshaft sprocket (2) is aligned with the orange link (D) one on timing chain, as shown in the figure.
