Installation Procedure
WARNING: This page is about a different variant/trim than selected.
- Determine the configuration of the balance chain.
- Install the balance shaft drive sprocket.
- For the 1st design balance chain, install the balance shaft drive chain with the colored links lined up with the marks on the balance shaft drive sprockets and the crankshaft sprocket. There are three colored links on the chain. Two links are of matching colors, and one link is of a unique color. Use the following procedure to line up the links with the sprockets:
- Orient the chain so that the colored links are visible.
- Place the uniquely colored link (1) so that it lines up with the timing mark on the intake side balance shaft sprocket.
- Working clockwise around the chain, place the first matching colored link (2) in line with the timing mark on the crankshaft drive sprocket, approximately 6 o'clock position on the crank sprocket.
- Place the chain (3) on the water pump drive sprocket. The alignment is not critical.
- Align the last matching colored link (4) with the timing mark on the exhaust side balance shaft drive sprocket.
- For the 2nd design balance chain, install the balance shaft drive chain with the black anodized links lined up with the marks on the balance shaft drive sprockets and the crankshaft sprocket. There are three timing links with a black anodized finish on the chain. One black anodized link has uniquely colored links on either side. Use the following procedure to line up the links with the sprockets:
- Orient the chain so that the colored links are visible.
- Place the black anodized link (1), with uniquely colored links on either side, so that it lines up with the timing mark on the intake side balance shaft sprocket.
- Working clockwise around the chain, place the next black anodized link (2) in line with the timing mark on the crankshaft drive sprocket, approximately 6 o'clock position on the crank sprocket.
- Place the chain (3) on the water pump drive sprocket. The alignment is not critical.
- Align the last black anodized link (4) with the timing mark on the exhaust side balance shaft drive sprocket.
- Install the upper balance shaft drive chain guide and bolts and tighten to 12 N.m (106 lb in).
- Install the small balance shaft drive chain guide and bolts and tighten to 12 N.m (106 lb in).
- Install the adjustable balance shaft chain guide and bolt and tighten to 10 N.m (89 lb in).
- Reset the timing chain tensioner by performing the following steps:
- Rotate the tensioner plunger 90 degrees in its bore and compress the plunger.
- Rotate the tensioner back to the original 12 o'clock position and insert a paper clip through the hole in the plunger body and into the hole in the tensioner plunger.
- Install the balance shaft drive chain tensioner and bolts and tighten to 10 N.m (89 lb in).
- Remove the paper clip from the balance shaft drive chain tensioner.
- Install the camshaft timing chain, sprocket, and tensioner. Refer to Camshaft Timing Chain, Sprocket, and Tensioner Replacement .
NOTE:
There are two possible chain configurations for the engine. Both configurations use a unique chain link to line up with the intake side balance shaft sprocket timing mark. The first design uses a unique link color (1). The second design uses a black anodized link (3) with uniquely colored links on either side (2).
NOTE:
If the balance shafts are not properly timed to the engine, the engine may vibrate or make noise.
CAUTION:
Refer to Fastener Caution .
