Installation Procedure
- Assemble the crankshaft sprocket, balancer shaft driven sprocket, and balancer chain. Ensure the timing link (1) lines up with the timing mark (2) on the crankshaft sprocket. Ensure that both timing teeth (3) on the balancer shaft driven sprocket line up with the timing links (4).
- Install the sprockets and chain (1) as an assembly to the crankshaft and balancer shaft assembly.
- Ensure the timing link (1) is aligned with the crankshaft sprocket timing mark (2).
- Ensure the adjacent timing links (4) are aligned with both of the timing marks (3) on the balancer shaft driven sprocket.
- Install the NEW balancer shaft driven sprocket bolt (1).
- Tighten the balancer shaft driven sprocket bolt to 40 N.m (30 lb ft) plus 50 degrees.
- Install the balancer chain guide (2).
- Install the balancer chain guide bolts (1). Tighten the bolts to 10 N.m (89 lb in).
- Install the balancer chain tensioner (2).
- Install the balancer chain tensioner bolts (1). Tighten the bolts to 10 N.m (89 lb in).
- Remove EN-50837 retention tool to restore the tension to the balancer chain.
- Install the timing chain. Refer to Camshaft Timing Chain and Tensioner Replacement .
- Install the camshaft cover. Refer to Camshaft Cover Replacement (LTG) , Camshaft Cover Replacement (LKW) .
NOTE:
Proper setup is critical to ensure correct timing when installing the sprockets and chain simultaneously onto the shafts. The timing links are heat treated blued steel.
NOTE:
The crankshaft keyway should be in the 12 O'clock position.
CAUTION:
This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or component.
CAUTION:
Refer to Fastener Caution .
NOTE:
Ensure the guide is installed in the correct orientation. The long end must point toward the crankshaft and the flat edge must be adjacent to the balance chain.
