CAUTION:
- To avoid possible camshaft damage, ensure the camshaft and camshaft sprocket are properly seated before tightening the camshaft sprocket bolt.
- To avoid possible engine performance issue due to mistiming, do not tighten the camshafts at this time.
Install the camshaft timing chain tension guide [bank 2 (1)], the camshaft timing chain slack guide [bank 2 (2)], the camshaft timing tensioner [bank 2 (3)], and tighten bolts (A). Verify that the left camshaft drive chain runs across the camshaft tension guide and camshaft chain tensioner.

NOTE:
- Make sure bushings are installed in camshaft timing chain tension guide (bank 2) before installation.
- Make sure the bushing are installed in camshaft timing chain slack guide [bank 2 (1)] before installation.
Remove the Tool (A) to apply tension to the camshaft timing chain (1).

Align the fuel pump sprocket (2) with the fuel pump dowel pin (A) and install it on the fuel pump (1).
Hand tighten the fuel pump sprocket nut (C).
CAUTION: Do not reuse the washer (B).
Install the fuel pump timing chain (1) on the fuel pump sprocket (2) and the crankshaft sprocket (oil/fuel pump) (3). Place the fuel pump timing chain on the rear teeth of the crankshaft sprocket (oil/fuel pump). Match the blue links (A) with the timing marks (B) on both sprockets.

NOTE:
- Make sure bushing (3) is installed in the fuel pump chain slack guide (2) before installation.
- Verify that the fuel pump chain runs across the guide and tensioner arm.

Tighten the nut for the fuel pump sprocket (1) while holding the sprocket with a suitable tool (A).
