Installation Procedure
Install the key into the crankshaft keyway (1).
- Tap the key (1) into the keyway until both ends of the key bottom onto the crankshaft.
Install the crankshaft sprocket (1). Align the crankshaft key with the crankshaft sprocket keyway.
- Remove the EN-42386-A Flywheel Holding Tool
- Rotate the crankshaft until the sprocket alignment mark (2) is in the 12 o'clock position.
- Install the EN-42386-A Flywheel Holding Tool
Compress the timing chain tensioner guide and install the EN-46330 tension pin (1).
Install the timing chain tensioner (1) and left side bolt (2) hand tight. Do not install the right side bolt at this time. The right side bolt will be installed after the camshaft position (CMP) actuator and chain have been installed onto the engine.
- WARNING:
Refer to Camshaft Position Actuator Removal and Installation Warning .
Remove the tie strap (1) from the actuator.
- NOTE:
- Properly locate the CMP actuator onto the locating pin of the camshaft.
- The sprocket teeth and timing chain must mesh
- The camshaft and the sprocket alignment marks MUST be aligned properly.
- Do not use the CMP solenoid valve again. Install a NEW valve during assembly.
Identify the alignment hole (1) in the rear face of the CMP actuator and the locating pin (2) on the front face of the camshaft.
- NOTE:
Use care to install the actuator completely onto the front of the camshaft. Never push on the reluctor wheel when attempting to install the actuator.
Install the CMP actuator and timing chain (1).
Inspect the sprockets for proper alignment. The mark on the CMP actuator sprocket (1) should be in the 6 o'clock position and the mark on the crankshaft sprocket (2) should be located in the 12 o'clock position.
- NOTE:
It is possible to push the camshaft rearward when installing the CMP actuator. Verify that the camshaft lobes are centered in the valve lifter bores after the CMP actuator is installed.
Locate a straight edge (1) across the front face of the engine block and inspect for proper installation of the CMP actuator and timing chain. With the CMP actuator properly and completely installed onto the front of the camshaft, the timing chain (2) will not protrude beyond the front face of the engine block.
- CAUTION:
Refer to Component Fastener tighten ing Caution .
Install a NEW CMP actuator solenoid valve (1). With the CMP actuator properly positioned onto the camshaft, the CMP actuator solenoid valve can be threaded completely into the camshaft using light hand pressure. tighten by hand until snug.
tighten
- First pass 65 N.m (48 lb ft)
- Final pass 90 degrees
- CAUTION:
Refer to Fastener Caution .
Install the right side bolt (1) onto the timing chain tensioner. tighten both bolts to 22 N.m (16 lb ft).
- Remove the EN-46330 tension pin (2).
- NOTE:
Ensure the balancer shaft (2) is installed with the flat spot facing the 3 o'clock position.
Install the balancer chain (3) by wrapping it around the camshaft actuator and the balancer shaft idler sprocket.
- Install the balance shaft driven sprocket (2), and balance shaft driven gear bolt (1) hand tight.
Ensure the lower blue link plate (3) of the balancer chain must align with the camshaft actuator triangle mark (4).
- Ensure the upper blue link plate (2) of the balancer chain must alight with the dot (1) on balance shaft driven sprocket. The 20 tooth driven sprocket will also have a molded in vertical line (1) pointing at 12 o'clock.
- NOTE:
If plastic shim is not available, a 1.1 mm (0.04 in) size shim will need to be placed between the balancer chain and guide during installation.
Install the balancer chain guide with shim (2) and bolts (1).
- Balance Shaft Retainer Bolt - Install and tighten [2x] 10 N.m (89 lb in)
Remove the EN-46330 tension pin (1).
- tighten the balance shaft driven gear bolt (3) to 58 N.m (43 lb ft).
- tighten the idler sprocket bolt (2) to 58 N.m (43 lb ft).
- The chain should now be tight. Remove the shim (4) from between the balancer guide and the chain. The chain should now be slightly loose.
