20. Remove the timing chain guide.

Pic 19

21. Remove the LH primary timing chain and crankshaft sprocket as an assembly.

Installation

pic 20

1. Reset the timing chain tensioners.
- Insert a fine wire and dislodge the check ball.
- Using finger pressure, compress the tensioner.
- Remove the wire.

Pic 21

2. NOTE: If the timing mark on the LH timing chain crankshaft gear is facing toward the rear of the engine, install the RH timing chain crankshaft gear with the mark facing forward. If the timing mark on the LH timing chain crankshaft gear is facing toward the front of the engine, install the RH timing chain crankshaft gear with the mark facing toward the rear of the engine.

NOTE: The camshaft holding tool should still be installed on the LH cylinder head.

Position the LH timing chain and crankshaft gear.
- Position the timing chain over the LH intake camshaft sprocket.
- Position the crankshaft gear in the timing chain.
- Position the timing chain and crankshaft gear over the crankshaft as an assembly.

3. Install the LH timing chain guide.

Pic 23

4. Install the LH timing chain tensioner arm.

Pic 24

5. CAUTION: The orientation of the blanking plate must be as shown or the oil galley will not seal, resulting in low oil pressure and possible engine damage.

Install the LH timing chain tensioner.
- Position the blanking plate.
- Install the LH timing chain tensioner and blanking plate.

Pic 25

6. Install a tie strap to take up the slack in the timing chain.

Pic 26

7. Using the special tool, apply tension to the LH exhaust camshaft sprocket and tighten the camshaft sprocket bolts in two stages.
- Stage 1: Tighten to 20 Nm (15 ft. Lbs.).
- Stage 2: Tighten an additional 90 degrees.

8. Remove the special tool.
9. Remove the tie strap.

Pic 28

10. Install the special tool on the right cylinder head.

11. NOTE: If the timing mark on the LH timing chain crankshaft gear is facing toward the rear of the engine, install the RH timing chain crankshaft gear with the mark facing forward. If the timing mark on the LH timing chain crankshaft gear is facing toward the front of the engine, install the RH timing chain crankshaft gear with the mark facing toward the rear of the engine.

Position the RH timing chain and crankshaft gear.
- Position the timing chain over the RH intake camshaft sprocket.
- Position the crankshaft gear in the timing chain.
- Position the timing chain and crankshaft gear over the crankshaft as an assembly.

Pic 31

12. Install the RH timing chain guide.

Pic 32

13. Install the RH timing chain tensioner arm.

Pic 33

14. CAUTION: The orientation of the blanking plate must be as shown or the oil galley will not seal, resulting in low oil pressure and possible engine damage.

Install the RH timing chain tensioner.
- Position the blanking plate.
- Install the RH timing chain tensioner and blanking plate.

Pic 34

15. Install a tie strap to take up the slack in the timing chain.

Pic 35

16. NOTE: The exhaust camshaft sprocket bolt must be fully tightened before tightening the intake camshaft sprocket bolt.

Using the special tool, apply tension to the RH exhaust camshaft sprocket and tighten the camshaft sprocket bolts in two stages.
- Stage 1: Tighten to 20 Nm (15 ft. Lbs.).
- Stage 2: Tighten an additional 90 degrees.

Pic 36

17. Remove the special tool.
- Remove the tie strap.
